can you give me an example of media queries where depending of 3 screen sizes you apply different css background-color classes

Sure, I'd be happy to help you understand media queries and how to apply different CSS background-color classes to different screen sizes.

Media queries allow you to apply different CSS styles based on the screen size. Here's a simple example of how you can apply different background-color classes to different screen sizes:

HTML:

```html
<style>
  @media (max-width: 600px) {
    .background-small {
      background-color: green;
    }
  }

  @media (min-width: 601px) and (max-width: 900px) {
    .background-medium {
      background-color: blue;
    }
  }

  @media (min-width: 901px) {
    .background-large {
      background-color: red;
    }
  }
</style>

<div class="background-small">Small screen</div>
<div class="background-medium">Medium screen</div>
<div class="background-large">Large screen</div>
```

In this example, each `@media` rule specifies a range of screen sizes. The `min-width` property sets a minimum width, and `max-width` sets a maximum width. The `and` operator means that both conditions must be true for this style to apply.

The CSS styles are defined within each `@media` rule. In this case, different background-color classes are assigned to the different blocks. When the screen size falls within each specific range, that corresponding class will be applied.

This is the basic structure of how media queries work. You can add more `@media` rules and style properties based on your specific design requirement. Hope this helps.

Certainly! Here's an example of a CSS code snippet using media queries to apply different `background-color` classes based on three different screen sizes:

```css
/* Default background color for mobile devices or small screens */
body {
  background-color: lightblue;
}

/* Media query for screens that are 600px wide or more */
@media (min-width: 600px) {
  body {
    background-color: lightgreen;
  }
}

/* Media query for screens that are 900px wide or more */
@media (min-width: 900px) {
  body {
    background-color: lightpink;
  }
}
```

In this example:

- The `body` background color is `lightblue` by default, which applies to small screens such as mobile phones.
- When the screen is 600px wide or more (e.g., tablets), the media query changes the `body` background color to `lightgreen`.
- When the screen is 900px wide or more (e.g., laptops and desktops), the media query changes the `body` background color to `lightpink`.
