I have searched SO for similar questions, but not found anything yet.

I want the main content aligned in the center of the page (at the moment, it is a bit to the right. It is best to see this in my code snippet below in full screen mode). I also want the `nav-bar` to touch the main content on the side.

I have tried things like:

```
margin: 0 auto;
text-align: center;
justify-content: center;

```

between all sorts of different elements to see a result, but not much really happens.

What am I missing?
