HTML and CSS Reference
In-Depth Information
Part 1. Introduction
It's important that you know about HTML5's semantic markup basics and wide variety of
APIs. For the introduction, we'll cover these concepts briefly, but in heavy detail, to ramp

However, you'll miss advanced markup concepts such as ARIA and microdata (if you aren't
already familiar with them).
