I took a look at the source code for the main page of howstuffworks.com. They are definitely using linked CSS — about 4 different sheets actually: one called basic.css, one called layout.css, one called blocks.css, and one called article.css. The source code is filled with Java-Script. And there is also many divisions — upon divisions, upon divisions…
As far as old school HTML goes, I’m seeing plenty of image and URL links. There is also plenty of unordered lists. I’m not seeing any tables though — they seem to have done the layout job entirely with div tags.
I’ve also taken a look at the code behind my My Yahoo page. The first half of the HTML page appears to be Java-Script for running the modules. The rest of the document is basically formatted as a bunch of div tags, with either a table or a Java-Script inside each div tag. Quite a few tables in the code.
