Design Designing in the Browser versus Adobe Illustrator

I followed the css part but "margin: 0 auto;" does not center anything. Any advice on how can I solve this problem?

I want to create a header and center it. I have searched everywhere but I don't seem to get it right.

Hi Stefan,

can we see all your code please?

Also does your header have a width? It needs a width set for margin: 0 auto; to work.

For e.g.

header {
width: 80%;
margin: 0 auto;
}
