Today, you'll learn the basics of CSS Grid by building 3 different grid layouts from scratch.
The first example is a responsive 12 column grid.
It replaces most of the use cases that you'd find in a grid system like Twitter Bootstrap, but it does so with only 3 lines of code and removes the need for all this crazy markup HTML.
Next, we'll build a responsive photo gallery.
And 3rd, we'll build an explicit grid that has this fancy, staggered intro animation.
By by the end of this video, you should know enough about grid to start putting it to use in your own projects.
If you're new here, like and subscribe, and feel free to grab your mouse and keyboard to code along with us.
When you start, Just have a good feeling and be happy and and love with life and the world and sit down and begin playing.
I'd like to start off by sharing my own experience with Grid.
Because on Fireship IO, I was previously using a flexbox based system, like you would find in Bootstrap and many other CSS frameworks.
Now, there's nothing wrong with using a third party solution, but when you use Grid, you don't have to add any additional CSS to your bundle size.
The grid system just works natively in the browser.
But, the much more important benefit was how much it simplified the codebase.
My HTML markup had a bunch of columns, each with its own collection of classes to make that column responsive.
After moving to CSS Grid, I was able to remove all these classes and implement my own grid system with just three lines of code.
And on top of that, beautiful designs that you would normally only find in a magazine are much easier to implement with Grid, because the system itself is inspired by print based grids.
Now, I should warn you that grid is pretty weird to learn at first.
So, let's jump into some examples and understand what every line of code is doing.
You can follow along by opening your editor and creating an HTML all in CSS file, or you can clone the project from GitHub and you'll see that each grid is broken down into its own HTML and CSS files.
This first grid building is basically an infinite set of responsive columns.
And that's really useful if you have something like a feed of cards, like the lesson feed on Fireship IO.
And a grid like this, we'll also replace many of the use cases for something like Twitter Bootstrap Grid.
Go ahead and open an HTML file in Versus Code, then can start typing HTML to autocomplete the boilerplate code.
Next, I'm going to go into the head of the document, add a style tag, and then import our Base CSS as well as our basic grid for this example.
The base CSS file is just something that I'm going to share across all the examples.
If we open that file, you'll notice that it has a card class that defines a flex box that aligns its content in the center.
None of this code is actually required for your grid to work, it's just there to make things look nice, so feel free to copy it from the main repo.
Now going back to our HTML, we'll go into the body and set up a section that will serve as our main grid container.
Then, all of the immediate children inside of this container are known as grid items.
Now, for this demo, I'm adding 12 children to the grid, but I'm assuming the content inside the grid is dynamic.
Meaning, we might have 3 items in there, 50 items, or whatever.
So what we need is an implicit grid that can figure out the right number of columns and rows based on the content size and the viewport size.
The first step is to set display grid on the container and You'll notice right now, everything is just stacked up in a single column.
Let's start by giving our children a little bit of spacing.
We can do that with the gap property Instead of setting margins on the children, that will guarantee that we always have 1 REM of spacing between the items both horizontally and vertically.
Now, Now, one way to create columns is to use the grid template columns property.
Let's start by creating an explicit grid, or a grid that has all of its columns defined in advance.
Now, since we're talking about columns, think about the width of the grid.
1 f r or 1 fractional unit represents one part of the available space.
Currently, we have 1 column, so 1 f r is a 100% of the available space.
We can add another column by simply adding another f r unit.
And now 1 f r equals 50% of the available space.
And we can keep doing this for as many columns as we need, or in our case, 12 columns.
The end result is an explicit grid that always has 12 columns.
But there's a few problems here.
First of all, this grid is not responsive and this code was really ugly.
Fortunately, CSS Grid has a helper function called repeat.
Instead of writing out each column manually, we can simply call repeat 12, and then pass in the unit that we want to repeat.
This code is identical to the code above, but much more concise and readable.
Now, currently in the demo, each column is too thin.
Let's look at how we can set a minimum width of 2 40 pixels.
We'll try again by repeating 12 columns, but this time use the min max function.
This is like saying make sure my columns don't go below 200 pixels in width, but allow them to expand as big as one fractional unit will allow.
What you'll notice is that our cards are no longer too skinny, but we now have Another problem.
They're overflowing on the horizontal axis.
So the question becomes, how do we make these columns break down into additional rows when there's no longer available space?
The answer is by creating an implicit grid.
When we call repeat, instead of repeating 12 times, we'll repeat with autofit and then use the same min max value you as before.
What autofit does is tell grid to calculate the number of rows and columns on the fly.
And now you can see that we have a truly responsive grid.
It only took 3 lines of code and no additional markup or classes in our HTML.
It's worth noting that there's also an autofill option.
The difference is subtle, but important.
Notice here in the demo how the The top autofill option is going to create additional columns when there becomes additional space, but autofit on the bottom will expand its children to take up all of the available space.
Now, Now, when you're working with Grid and things aren't going the way you expect, open up Firefox Dev Tools.
It has a really good grid and Flexbox inspector.
And, you can see here how it allows me to visualize the lines and tracks on the grid.
Now, it's time to move on to example number 2.
A responsive mosaic photo gallery.
What you'll notice about this example, is that some of the photos are bigger, some are taller, and some are wider.
And, they also reposition themselves gracefully when the viewport size changes.
Let's start by going into the HTML and setting up a grid container.
Inside the container, we have 12 divs like we did in the previous example, but each div has a photo URL as its background.
And, by the way, these are free to use photos from Unsplash.
Now if we go into the CSS, we'll use the code from the previous example as our starting point, but you'll notice the rows in the grid are very short.
That's because they're being automatically sized to the text content in the children.
Now, when you have an implicit grid like this, it can be useful to set the size of the row.
If we want all of our rows to be exactly 240 pixels tall, we can set the grid auto rows property to that value.
And now each automatically created row will be fixed to that height.
Now our goal is to change the sizing of individual grid items.
Let's create a class called card tall.
Any item with this class should span across multiple rows vertically.
We can do that with the grid row property and then span2 will tell it to span across 2 rows from its starting position.
We can use a slash to also specify its ending point, which in this case can be figured out automatically by the grid algorithm.
So, the grid row property is like saying start here slash end here.
It makes more sense when you look at your grid in Firefox and display the grid line numbers.
If we look at the first photo, you can see it starts at column 1 row 1, then ends at column 2 row 2.
If we want to make this photo taller, we can do so explicitly with the grid row property.
Like saying start at horizontal line 1 and end at horizontal line 4.
And now you can see that photo spans across 3 rows and everything else was repositioned accordingly.
But, since we don't want to use the line numbers explicitly, we'll use span 2 to say start wherever, span 2 rows, and then automatically end wherever.
So that's how we can make an item taller.
If we want to make an item wider, we can use the grid column property and we can implement it with the exact same value.
And now, we can go into our HTML and start applying these classes to the items.
The end result is a responsive photo gallery, but there is one slight problem.
At smaller sizes, spanning 2 grid lines doesn't work very well.
Notice how the items on the right are way too skinny.
We can easily fix this by wrapping our classes in a media query.
This means the classes will do nothing on smaller screen sizes and will only be applied if the min width is greater than 600 pixels in the viewport.
And now things will look much better on small devices.
And that brings us to grid number 3.
It has this intro animation and notice how each A grid item comes in clockwise until it gets to the center.
You'll also notice the color changes as it's being animated in and the middle columns are responsive based on the viewport size.
Now, again, we have the same basic HTML structure, just a bunch of divs inside a grid.
We'll set the display to grid, give it a gap, but this time we're went to create an explicit grid using grid template areas.
This is a really cool property that allows you to create an explicit grid by giving names to the different areas in the grid.
Notice how we have the letter a in the top left and if we follow that clockwise it goes all the way to l and then in the middle we're actually using emojis to represent the main content.
And A shout out to Paul Newton who commented on the last video explaining how you can get even more abstract with your grid area names.
Notice how he's using shapes to define the grid areas, making it extremely clear which part of the UI each grid area is for.
Now, once you have your grid template areas defined, you can set some sizing for the rows and columns.
In this example, the grid container has a fixed height, so we'll have each individual row take up exactly 25% of the height using the repeat function.
When it comes to our columns, we'll give the 1st column a fixed width, the 2 middle columns an auto property to automatically resize based on the viewport, and then the last column a fixed width of also 240.
Then the next step is to place the children in their appropriate grid area.
Now, because I have all the children laid out in a logical order, I'm going to use nth child to select them, but you could definitely use your own custom class names here as well.
The important thing to notice is that we're applying grid area a to this element.
No matter where it sits in the container, it will take up that grid template area you defined above.
Now, we'll repeat this process for every single area in the grid.
The end result is this grid with all children in the appropriate spots.
And now, how do we impress our friends with this fancy staggered intro animation?
Well, the first thing I'm going to do is set up a variable for the staggered delay.
This will allow us to change the timing without having to manually update the delay for all 13 elements.
Next, we're going to need a keyframes animation.
If you're not familiar with keyframes, they basically allow you to move from one set of properties to another.
From is the starting point, to is the ending point.
We want to start with an opacity of 0 or invisible, a scale of 0.3, and then we'll also rotate the color by a 180 degrees.
That's how I create that rainbow like color change when the items are animated in.
When the animation's complete, the opacity should be 1, the scale should be 1, and the hue rotate should be 0.
Now, CSS will automatically interpolate between the starting and ending values based on the amount of time that we specify for the animation.
We can apply this animation to all the cards by setting it as the animation name.
Then, we'll also give it a duration of 700 milliseconds and a timing function of ease out.
Now, one last important point here is that we also need to set the animation fill mode to backwards.
This will set the elements to their first key frame value which, in our case, will be invisible.
Otherwise, the cards would be visible before the animation starts and that just wouldn't look right at all.
That takes care of the animation, but now we want to stagger it.
And We can do that by setting an animation delay on each individual element.
But, we want to do this in a smart way, so if we decide to change the delay, We don't have to update all 13 items.
To help us, I'm going to use the CSS calc function.
It can perform basic calculations on values.
For the first item, we'll say 1 times the stagger delay.
For the second item, we'll say 2 times the stagger delay and we'll keep increasing that for all 13 items.
And And, there's still obviously a lot of code duplication here, but you could make this much more efficient by using something like Sass, where you can run a programmatic for loop.
And, that's basically all there is to it.
We now have this unique animated grid without any JavaScript or external CSS framework.
I'm gonna go ahead and wrap things up there.

Fortunately, CSS Grid has a helper function called repeat. Instead of writing out each column manually, we can simply call repeat 12, and then pass in the unit that we want to repeat. This code is identical to the code above, but much more concise and readable. Now, currently in the demo, each column is too thin. Let's look at how we can set a minimum width of 2 40 pixels. We'll try again by repeating 12 columns, but this time use the min max function. This is like saying make sure my columns don't go below 200 pixels in width, but allow them to expand as big as one fractional unit will allow. What you'll notice is that our cards are no longer too skinny, but we now have Another problem. They're overflowing on the horizontal axis. So the question becomes, how do we make these columns break down into additional rows when there's no longer available space? The answer is by creating an implicit grid. When we call repeat, instead of repeating 12 times, we'll repeat with autofit and then use the same min max value you as before. What autofit does is tell grid to calculate the number of rows and columns on the fly. And now you can see that we have a truly responsive grid. It only took 3 lines of code and no additional markup or classes in our HTML. It's worth noting that there's also an autofill option. The difference is subtle, but important. Notice here in the demo how the The top autofill option is going to create additional columns when there becomes additional space, but autofit on the bottom will expand its children to take up all of the available space. Now, Now, when you're working with Grid and things aren't going the way you expect, open up Firefox Dev Tools. It has a really good grid and Flexbox inspector.
And, you can see here how it allows me to visualize the lines and tracks on the grid. Now, it's time to move on to example number 2. A responsive mosaic photo gallery. What you'll notice about this example, is that some of the photos are bigger, some are taller, and some are wider. And, they also reposition themselves gracefully when the viewport size changes. Let's start by going into the HTML and setting up a grid container.

geometry
Inside the container, we have 12 divs like we did in the previous example, but each div has a photo URL as its background. And, by the way, these are free to use photos from Unsplash. Now if we go into the CSS, we'll use the code from the previous example as our starting point, but you'll notice the rows in the grid are very short. That's because they're being automatically sized to the text content in the children. Now, when you have an implicit grid like this, it can be useful to set the size of the row. If we want all of our rows to be exactly 240 pixels tall, we can set the grid auto rows property to that value. And now each automatically created row will be fixed to that height. Now our goal is to change the sizing of individual grid items. Let's create a class called card tall. Any item with this class should span across multiple rows vertically. We can do that with the grid row property and then span2 will tell it to span across 2 rows from its starting position. We can use a slash to also specify its ending point, which in this case can be figured out automatically by the grid algorithm. So, the grid row property is like saying start here slash end here. It makes more sense when you look at your grid in Firefox and display the grid line numbers.
If we look at the first photo, you can see it starts at column 1 row 1, then ends at column 2 row 2. If we want to make this photo taller, we can do so explicitly with the grid row property. Like saying start at horizontal line 1 and end at horizontal line 4.
photography
And now you can see that photo spans across 3 rows and everything else was repositioned accordingly. But, since we don't want to use the line numbers explicitly, we'll use span 2 to say start wherever, span 2 rows, and then automatically end wherever. So that's how we can make an item taller. If we want to make an item wider, we can use the grid column property and we can implement it with the exact same value.
And now, we can go into our HTML and start applying these classes to the items. The end result is a responsive photo gallery, but there is one slight problem. At smaller sizes, spanning 2 grid lines doesn't work very well. Notice how the items on the right are way too skinny.
graphic design
We can easily fix this by wrapping our classes in a media query.
This means the classes will do nothing on smaller screen sizes and will only be applied if the min width is greater than 600 pixels in the viewport. And now things will look much better on small devices. And that brings us to grid number 3. It has this intro animation and notice how each A grid item comes in clockwise until it gets to the center. You'll also notice the color changes as it's being animated in and the middle columns are responsive based on the viewport size.

geometry
Now, again, we have the same basic HTML structure, just a bunch of divs inside a grid.
We'll set the display to grid, give it a gap, but this time we're went to create an explicit grid using grid template areas. This is a really cool property that allows you to create an explicit grid by giving names to the different areas in the grid. Notice how we have the letter a in the top left and if we follow that clockwise it goes all the way to l and then in the middle we're actually using emojis to represent the main content. And A shout out to Paul Newton who commented on the last video explaining how you can get even more abstract with your grid area names. Notice how he's using shapes to define the grid areas, making it extremely clear which part of the UI each grid area is for. Now, once you have your grid template areas defined, you can set some sizing for the rows and columns. In this example, the grid container has a fixed height, so we'll have each individual row take up exactly 25% of the height using the repeat function.
geometry
When it comes to our columns, we'll give the 1st column a fixed width, the 2 middle columns an auto property to automatically resize based on the viewport, and then the last column a fixed width of also 240.
Then the next step is to place the children in their appropriate grid area. Now, because I have all the children laid out in a logical order, I'm going to use nth child to select them, but you could definitely use your own custom class names here as well. The important thing to notice is that we're applying grid area a to this element.
children
No matter where it sits in the container, it will take up that grid template area you defined above.
Now, we'll repeat this process for every single area in the grid. The end result is this grid with all children in the appropriate spots. And now, how do we impress our friends with this fancy staggered intro animation? Well, the first thing I'm going to do is set up a variable for the staggered delay. This will allow us to change the timing without having to manually update the delay for all 13 elements. Next, we're going to need a keyframes animation. If you're not familiar with keyframes, they basically allow you to move from one set of properties to another. From is the starting point, to is the ending point. We want to start with an opacity of 0 or invisible, a scale of 0.3, and then we'll also rotate the color by a 180 degrees. That's how I create that rainbow like color change when the items are animated in. When the animation's complete, the opacity should be 1, the scale should be 1, and the hue rotate should be 0. Now, CSS will automatically interpolate between the starting and ending values based on the amount of time that we specify for the animation. We can apply this animation to all the cards by setting it as the animation name. Then, we'll also give it a duration of 700 milliseconds and a timing function of ease out. Now, one last important point here is that we also need to set the animation fill mode to backwards. This will set the elements to their first key frame value which, in our case, will be invisible. Otherwise, the cards would be visible before the animation starts and that just wouldn't look right at all. That takes care of the animation, but now we want to stagger it. And We can do that by setting an animation delay on each individual element. But, we want to do this in a smart way, so if we decide to change the delay, We don't have to update all 13 items.

graphic design
geometry
To help us, I'm going to use the CSS calc function. It can perform basic calculations on values. For the first item, we'll say 1 times the stagger delay.
For the second item, we'll say 2 times the stagger delay and we'll keep increasing that for all 13 items. And And, there's still obviously a lot of code duplication here, but you could make this much more efficient by using something like Sass, where you can run a programmatic for loop. And, that's basically all there is to it. We now have this unique animated grid without any JavaScript or external CSS framework. I'm gonna go ahead and wrap things up there.

Today, you'll learn the basics of CSS Grid by building 3 different grid layouts from scratch. The first example is a responsive 12 column grid. It replaces most of the use cases that you'd find in a grid system like Twitter Bootstrap, but it does so with only 3 lines of code and removes the need for all this crazy markup HTML. Next, we'll build a responsive photo gallery. And 3rd, we'll build an explicit grid that has this fancy, staggered intro animation. By by the end of this video, you should know enough about grid to start putting it to use in your own projects. If you're new here, like and subscribe, and feel free to grab your mouse and keyboard to code along with us. When you start, Just have a good feeling and be happy and and love with life and the world and sit down and begin playing. I'd like to start off by sharing my own experience with Grid. Because on Fireship IO, I was previously using a flexbox based system, like you would find in Bootstrap and many other CSS frameworks. Now, there's nothing wrong with using a third party solution, but when you use Grid, you don't have to add any additional CSS to your bundle size. The grid system just works natively in the browser. But, the much more important benefit was how much it simplified the codebase. My HTML markup had a bunch of columns, each with its own collection of classes to make that column responsive. After moving to CSS Grid, I was able to remove all these classes and implement my own grid system with just three lines of code. And on top of that, beautiful designs that you would normally only find in a magazine are much easier to implement with Grid, because the system itself is inspired by print based grids. Now, I should warn you that grid is pretty weird to learn at first. So, let's jump into some examples and understand what every line of code is doing. You can follow along by opening your editor and creating an HTML all in CSS file, or you can clone the project from GitHub and you'll see that each grid is broken down into its own HTML and CSS files. This first grid building is basically an infinite set of responsive columns. And that's really useful if you have something like a feed of cards, like the lesson feed on Fireship IO. And a grid like this, we'll also replace many of the use cases for something like Twitter Bootstrap Grid. Go ahead and open an HTML file in Versus Code, then can start typing HTML to autocomplete the boilerplate code. Next, I'm going to go into the head of the document, add a style tag, and then import our Base CSS as well as our basic grid for this example. The base CSS file is just something that I'm going to share across all the examples. If we open that file, you'll notice that it has a card class that defines a flex box that aligns its content in the center. None of this code is actually required for your grid to work, it's just there to make things look nice, so feel free to copy it from the main repo. Now going back to our HTML, we'll go into the body and set up a section that will serve as our main grid container. Then, all of the immediate children inside of this container are known as grid items. Now, for this demo, I'm adding 12 children to the grid, but I'm assuming the content inside the grid is dynamic. Meaning, we might have 3 items in there, 50 items, or whatever. So what we need is an implicit grid that can figure out the right number of columns and rows based on the content size and the viewport size. The first step is to set display grid on the container and You'll notice right now, everything is just stacked up in a single column. Let's start by giving our children a little bit of spacing. We can do that with the gap property Instead of setting margins on the children, that will guarantee that we always have 1 REM of spacing between the items both horizontally and vertically. Now, Now, one way to create columns is to use the grid template columns property. Let's start by creating an explicit grid, or a grid that has all of its columns defined in advance. Now, since we're talking about columns, think about the width of the grid. 1 f r or 1 fractional unit represents one part of the available space. Currently, we have 1 column, so 1 f r is a 100% of the available space. We can add another column by simply adding another f r unit. And now 1 f r equals 50% of the available space. And we can keep doing this for as many columns as we need, or in our case, 12 columns. The end result is an explicit grid that always has 12 columns. But there's a few problems here. First of all, this grid is not responsive and this code was really ugly. Fortunately, CSS Grid has a helper function called repeat. Instead of writing out each column manually, we can simply call repeat 12, and then pass in the unit that we want to repeat. This code is identical to the code above, but much more concise and readable. Now, currently in the demo, each column is too thin. Let's look at how we can set a minimum width of 2 40 pixels. We'll try again by repeating 12 columns, but this time use the min max function. This is like saying make sure my columns don't go below 200 pixels in width, but allow them to expand as big as one fractional unit will allow. What you'll notice is that our cards are no longer too skinny, but we now have Another problem. They're overflowing on the horizontal axis. So the question becomes, how do we make these columns break down into additional rows when there's no longer available space? The answer is by creating an implicit grid. When we call repeat, instead of repeating 12 times, we'll repeat with autofit and then use the same min max value you as before. What autofit does is tell grid to calculate the number of rows and columns on the fly. And now you can see that we have a truly responsive grid. It only took 3 lines of code and no additional markup or classes in our HTML. It's worth noting that there's also an autofill option. The difference is subtle, but important. Notice here in the demo how the The top autofill option is going to create additional columns when there becomes additional space, but autofit on the bottom will expand its children to take up all of the available space. Now, Now, when you're working with Grid and things aren't going the way you expect, open up Firefox Dev Tools. It has a really good grid and Flexbox inspector. And, you can see here how it allows me to visualize the lines and tracks on the grid. Now, it's time to move on to example number 2. A responsive mosaic photo gallery. What you'll notice about this example, is that some of the photos are bigger, some are taller, and some are wider. And, they also reposition themselves gracefully when the viewport size changes. Let's start by going into the HTML and setting up a grid container. Inside the container, we have 12 divs like we did in the previous example, but each div has a photo URL as its background. And, by the way, these are free to use photos from Unsplash. Now if we go into the CSS, we'll use the code from the previous example as our starting point, but you'll notice the rows in the grid are very short. That's because they're being automatically sized to the text content in the children. Now, when you have an implicit grid like this, it can be useful to set the size of the row. If we want all of our rows to be exactly 240 pixels tall, we can set the grid auto rows property to that value. And now each automatically created row will be fixed to that height. Now our goal is to change the sizing of individual grid items. Let's create a class called card tall. Any item with this class should span across multiple rows vertically. We can do that with the grid row property and then span2 will tell it to span across 2 rows from its starting position. We can use a slash to also specify its ending point, which in this case can be figured out automatically by the grid algorithm. So, the grid row property is like saying start here slash end here. It makes more sense when you look at your grid in Firefox and display the grid line numbers. If we look at the first photo, you can see it starts at column 1 row 1, then ends at column 2 row 2. If we want to make this photo taller, we can do so explicitly with the grid row property. Like saying start at horizontal line 1 and end at horizontal line 4. And now you can see that photo spans across 3 rows and everything else was repositioned accordingly. But, since we don't want to use the line numbers explicitly, we'll use span 2 to say start wherever, span 2 rows, and then automatically end wherever. So that's how we can make an item taller. If we want to make an item wider, we can use the grid column property and we can implement it with the exact same value. And now, we can go into our HTML and start applying these classes to the items. The end result is a responsive photo gallery, but there is one slight problem. At smaller sizes, spanning 2 grid lines doesn't work very well. Notice how the items on the right are way too skinny. We can easily fix this by wrapping our classes in a media query. This means the classes will do nothing on smaller screen sizes and will only be applied if the min width is greater than 600 pixels in the viewport.

The speakers discuss the benefits of using CSS Grid for responsive grid design, including avoiding unnecessary code and easy implementation. They then move on to examples of responsive grid design using a base grid and a grid template, including setting display grid and grid image columns, using grid grid row properties to create an explicit grid, and creating a responsive grid by using a template area and keyframes. They also explain how to use the grid for responsive responsive photo gallery, including setting height of rows, creating a responsive grid by using a template area, and using the CSS calc function to set the animation delay and fill mode. Finally, they provide a link for a full source code on Fire KA IO for setting the animation delay and fill mode.
