Centering Navigation?

Without a link to your site, I doubt anyone will be able to help you very much.

sorry. my website is https://chevymaro.freehostia.com

Find the following code in style.css:

#header #menu {
float:left;
margin:70px 80px 0 0;
}

and change it to this:

#header #menu {
float:left;
margin:70px 80px 0 170px;
}

adjust the 170 value to fine tune.

thank you very much! ill try that.

IT worked! thanks so much!
