Your excitement at the prospect of a cutting-edge HTML5 site may be tempered by the following questions:
How can I accommodate browsers that have yet to support many of HTML5’s elements?
What are the current best practices for coding a standards-compliant, cross-browser-compatible HTML5 website?
In this chapter you will learn how to test for supported HTML5 features within a browser, and the latest techniques for accommodating those features that aren’t supported. You will learn how to get started quickly with an HTML5 boilerplate template that includes all of the latest tricks, techniques, and best practices for implementing HTML5 technologies.
