Why is my YouTube iframe empty?

I have the following iframe:

<iframe width=“370” height=“300” frameborder=“0” type=“text/html” url=“http://www.youtube.com/embed/4p0DsVPkyZg” name=“video”></iframe>

at the page:


But it is empty on Firefox 11.0 and on Chromium 18.0

The same problem occurs with a Vimeo url.

Any idea ?



The HTML specifications for an iframe show that the src attribute is used to determine where the content comes from, not one called url.

Sometimes, I wonder what is happening to me… Am I sleepcoding ?
