Possible to add navigation links using CSS?

The short answer: no.

The longer answer: The idea behind CSS is that it styles a webpage. The X/HTML holds the content. Ideally the two are completely seperate, though often time people include CSS inside the X/HTML. So, when you are talking about content it will always be in the X/HTML only. When you are talking about the styling of the page it will *usually* be in the CSS only, but can also be in the X/HTML.

Navigation is content. Can't be done in CSS. (sorry)

EDIT: But I see you have access to the HTML so why not use that?

Something like this before the page body div:

Code:

<div id="navigation">
<a href="http://mylink.com/">My Link</a>
<a href="http://my_other_link.com/">My Other Link</a>
</div>

 

CSS is not the way to go to solve your problem and it can't solve your problem.
