HTML and CSS Reference
Figure 11-1 The About page with video.
Styling for the default browser controls has not been standardized, so these controls may look slightly different de-
pending on which browser the video is being viewed in.
As I mention earlier in this chapter, there is no single universal video format. If you were to open your About
page in a browser that doesn't support the WebM format (such as Safari), you would see that the video never loads.
You can solve this problem by providing multiple video files to the browser. The browser then chooses the one it can
play and ignores the rest.
