Learn HTML by building, tag by tag

HTML is the skeleton of every website you have ever opened. It is also the most forgiving place to start coding: an element in, a page out. On Codeglass you write real markup from the first lesson, and we check it the way a browser would parse it — strict about closing tags, relaxed about the spaces that do not matter.
