Most likely, you've been led here because you're starting to use Dreamweaver to format your website. Here, I provide a simple start to website editing and formatting. There are a few lessons that describe the "behind the scenes view" including the code, and how to understand the code. There are lessons that take those attributes and show you how Dreamweaver can help you do all those things in Design mode.
This tutorial has undergone a facelift and some revisions, and still is going to be updated with fresh information. :-)
NB: The "Try it Yourself" features at the bottom of the HTML coding pages correspond, and build upon the thing you learned in the previous category.
