If someone could tell me how to correct my site when viewed with firefox I would greatly appreciate it. Site: Dnam.net In IE it looks fine, but if you look at it with firefox the column headers are "doubled" and the footer is spaced weird. *note the site is still under construction. Thanks!
The way you've written the site, you cannot call it XHTML. You either need to change the type declared on the top (to HTML 4 or so), or write the page for XHTML. For example, you have some tags written in CAPS (not allowed), you're using valign or align center, and sometimes you have images without the xhtml ending ( />) like this <img border="0" src="http://www.dnam.net/dnam/images2/dnamlogo.png" width="212" height="88"> Some of your other images have the correct ending, though. That may not fix your appearance problem, but it is something you need to do anyway.
