This will be the first of a series of blog posts to help someone new to HTML5 development. The first item to address is: What is meant by the term HTML5? I like to think of it as “Triple S” or SSS.
Source refers to the HTML markup itself, the tags.
Style refers to the inline styles and/or modules from CSS3.
For an introduction to these terms in slightly more detail, please read the first article I co-authored with Daniel Egan.
