Is this a 2-column elastic, liquid, fixed or hybrid layout? (I'm using Dreamweaver's CS3 terms) http://www.alejandrofernandez.com/
I'd agree with the above, it looks fixed to me. When you resize your browser window, the web page's content doesn't change, where as on a liquid layout it would.
Definitely fixed. Elastic will expand and contract when text size is adjusted and liquid will expand and contract when the browser window is resized.
