What Is HTML5?


HTML5: Everyone’s using it, nobody knows what it is. I realize that sounds more like a line out of an existential movie — maybe Waiting for Godot or a screenplay by Sartre — than a statement about HTML5. But it’s really the truth: most of the people using HTML5 are treating it as HTML4+, or
