I converted the homepage to » XHTML 1.0 Strict (document type declaration) from XHTML 1.0 Transitional (which applies the rules associated with rendering web pages more loosely).
Only problem I had was the square Google AdSense ad, which I've traditionally wrapped in a <table> tag/element .. which is not the correct way to code it. (Cuz it's not really a table. Rather it's a JavaScript script.)
In Strict, I needed to convert the <table> to a <div> and "float it" left (in CSS) .. otherwise none of the other text would wrap up alongside the ad (like it does now).
All the images in the center section had to be assigned a class and 'floated' right (in CSS), cuz the Strict DTD does not allow you to align="right" .. like I used to do.
Aligning deals with "presentation" (as opposed to structure and content), and the Strict DTD moves everything pertaining to presentation out of XHTML (and into CSS).
I'm actually fairly comfortable with the requirements of the XHTML 1.0 Strict DTD .. enough to begin creating all new pages using the Strict doc-type declaration.
