No. "display: none" is defined to affect all media, and that certainly
should not change for <audio> and <video>.
I think this is different than screen readers not speaking
display:none text. Both hiding layout frames and silencing screen
readers only affect the 'rendering' of the contained text, it doesn't
otherwise deactivate the contained display:none elements:
What matters is how display: none is defined [1], and as fantasai
mentioned display is media: all, with special processing to boot:
This value causes an element to generate no boxes in the
formatting structure (i.e., the element has no effect on
layout). Descendant elements do not generate any boxes
either; this behavior cannot be overridden by setting the
'display' property on the descendants.
Please note that a display of 'none' does not create an
invisible box; it creates no box at all.
Yes, so I think that a screen reader should not say whatever it would
normally say when hitting a <video> that is display:none.
However I see that as very different from silencing the audio stream
coming from the video. The audio stream in a video is not what the
screen reader would normally say when encountering a <video>, so I don't
think that neither the voice-volume nor the display property should
affect it.
Do you consider it against the CSS spec that display:none stylesheets
still are applied to the document? Or should that simply mean that
display:none stylesheets should not be rendered or spoken by a screen
reader?
