Hi there,
I had a problem embedding video from youtube in my blog. Myblog was perfectly valid in xhtml transitional, but once i embedded the video it didn’t validate anymore.
This was the original code from youtube:
<object classid=”clsid:d27cdb6e-ae6d-11cf-96b8-444553540000″ width=”425″ height=”344″ codebase=”http://download.macromedia.com/pub/shockwave/cabs/
flash/swflash.cab#version=6,0,40,0″><param name=”allowFullScreen” value=”true” /><param name=”src” value=”http://www.youtube.com/v/Z-DVi0ugelc&hl=en&fs=1″ />
<embed type=”application/x-shockwave-flash” width=”425″ height=”344″ src=”http://www.youtube.com/v/Z-DVi0ugelc&hl=en&fs=1″ allowfullscreen=”true”></embed>
</object>
The code above doesn’t validate in xhtml transitional. » Read more..
