hidden attribute (set to
"true"), it is possible to hide any visual element that
may otherwise appear with the embedded content. Typically it may be used
for audio content whereby not including the attribute would
result in the transport controls (play, pause, etc) being visible
underneath the audio.
attribute set to
"true" to hide the transport control
on some audio:
<embed src="Crash.wav" hidden="true"></embed>
Browser support is patchy. Some browsers were effective in hiding the transport controls while others hid the controls but still reserved a large space on the page for invisible content. Best advice is to avoid using this attribute unless you are absolutely sure of the browsers that your audience are using (for example, an Intranet).
