Description Simon Pieters 2008-08-07 13:53:45 UTC
AFAICT the <video>.width/height DOM attributes don't have default values defines as far as reflecting attributes go, and so getting .width or .height will return 0 when the content attributes aren't there (or won't parse). This seems unhelpful.

We think the width/height DOM attributes should return the rendered width/height of the element, if it's being rendered, or else the intristic width/height of the video element's playback area.
Comment 1 Olivier Gendrin 2008-08-07 14:40:34 UTC
For example, width should be 100% of parent width (see CSS) and height 100%*3/4 of parent width.
Comment 2 Ian 'Hixie' Hickson 2008-08-11 23:32:07 UTC
If you want the video dimensions, use videoWidth and videoHeight. If you want the dimensions of the rendering, use the CSS object model (clientHeight, etc). As a general rule, the DOM attributes don't return values other than what the content attributes have. There are some exceptions, like Image.height, but I think we want to keep the platform as consistent as possible.
