Guideline:
Allow the user to turn on and off rendering of video. [Priority 1]
(Checkpoint 3.3)
Techniques:

Allow the user to turn off video through the user agent user interface.
Render a still image in its place.
Support the 'display' property in CSS ([CSS2], section 9.2.5).
Allow the user to hide a video presentation from view, even though it
continues to play in the background.

new
Support the 'visibility' property in CSS ([CSS2], section 11.2). Using
visibility="hidden" allows a blank place holder box to be rendered in place
of the video on the screen while retaining the layout of the page.

Support the 'display' property in CSS ([CSS2], section 9.2.5). Using
display="none" removes the rendering of the video completely and may cause
the layout of the page to be changed.
