Chapter 6: Images, Rich Media, Audio, and Video in HTML5

C H A P T E R   6

Images, Rich Media, Audio, and Video in HTML5

In this chapter, you'll see how to make images and other rich media accessible using HTML5. This chapter will cover some tried and trusted ways of making graphical content accessible, as well as some new techniques you might not be familiar with. I'll cover other elements used to handle rich media, such as <audio> and <video>, and discuss how the new elements can be used to present audio and visual content in a way that is accessible.

In terms of “new” features in HTML5, nothing is quite as conspicuous as the new <canvas> element. <canvas> is a 2D drawing API that can be used to create some very sophisticated, graphically rich animations natively within the browser. However, <canvas> content does have some particular accessibility challenges. I'll discuss these later on.
