This article aims to consolidate some of this body into a more readily digestible resource for developers. Note that this article does not go into usage of HTML5 canvas. Performance testing To address the quickly changing world of HTML5 canvas, JSPerf (jsperf.com) tests verify that every proposed optimization still works.

So as to avoid confusion regarding the normativity of this section, RFC2119 terms have not been used. Instead, the term "expected" is used to indicate behavior that will lead to this experience. For the purposes of conformance for user agents designated as supporting the suggested default rendering, the term "expected" in this section has the same conformance implications as the RFC2119-defined term "must". 10.1 Introduction In general, user agents are expected to support CSS, and many of the suggestions in this section are expressed in CSS terms.
