The first link is a very basic explanation of floated elements and how they work. Not really a whole lot of extra info here, but useful for those who might still be having trouble with the concept.

Okay, my third link is 5 years old and I know we were’nt supposed to use something so old, but it is one of the most comprehensive articles I could find without any “hacks” to get around browser issues, though it does mention the hopelessness of designing for IE at the time the article was posted.
Ultimately I didn’t learn a whole lot from these articles, just a review and validation of what I already understood. I hope I’m not missing some important information.
