Summary
This chapter provided you with all the information you need to get started in modern web development. I disambiguated the common meaning of HTML5 and introduced you to the web platform. You learned what HTML5 is useful for and how to start writing it, and you also had a brief introduction to CSS3.
The chapter’s key messages are in the latter parts: First, always keep up-to-date about the levels of implementation of web platform features across common browsers; and second, test, and then test, test, test some more, and when you think you have no more testing to do, test again. Then once more for good luck.
With all of that explained, let’s roll our sleeves up and get to work.
