Chapter 10Mutimedia: The track
Element
In the last chapter, we discussed how to
make your media available to more users with cross-browser techniques. In
this chapter, we'll look at how to make it accessible and "index-able", too,

element and WebVTT.

-
Lack of accessibility.
-
Lack of "index-ability".
-
Language barriers between the media and the viewer or listener.
Accessibility simply means supporting users with impairments or disabilities as fully as possible. Audible media isn't usable to hearing-impaired users. Visually-impaired users don't see visual media in the same way that fully-sighted users do. HTML5 audio and video present clear challenges for these users.
