Hey, I have a few questions that I would like to put at ease in my mind that have really been bugging me. Are tables and frames the only way to make an HTML/XHTML layout without CSS? I thought this to be true but I am unsure. The other problem I am having is that I would like a more simple explanation on just what the XML name space is for, specifically, why the xmlns=w3.org is at almost every website's source on the Web in the header? I kind of read a few sites trying to explain name-spaces but I am still having a hard time grasping the information. Any replies at all would be appreciated. Thanks.

For the most part, yes. The header at the top of a DOCTYPE, which tells the web page who to interpret the markup of your page according to the World Web Consortium. Per the doctype you use, you can only the markup associated to that.
