HTML5: The Specification for Website Developers

At almost 1,000 pages, the HTML5 specification from the W3C can seem a bit daunting.

However, the reason for this extremely wordy specification is to clear up a lot of ambiguity that existed in previous specifications targeted at browser vendors and producers of related software. This is actually a good thing, since it locks down the behaviour and rules that browsers have to obey, meaning that web developers can be more sure of conformity across browsers.

But that does mean that the specification is full of sections that are just not relevant to the creators of websites.
