XHTML 1.0 and HTML 4.01 are Essentially the Same Thing

XHTML is the next version of HTML. This class will teach all the same concepts as the HTML 101 course, but focused on valid and well-formed XHTML.

After you finish this free course, you will understand the basics of XHTML, and some more advanced topics. With interactive lessons and the option to work with other people in the course, you'll be able to learn HTML the way you want. Go at your own pace, or follow along with the weekly syllabus.
