I'm working on a html 4.01/css2 valid theme (which is
pretty much done) but Chatterblock is not html 4.01 or
css2 compliant. Here is what I've found so far...
For css all you have to do is change all the
'cb_whatever' to 'cb-whatever' since the '_' character
isn't supported.
The major issues for HTML the following has to be done:
*all img tags need the 'alt' attribute
*all script tags need the type attribute
(type="text/javascript" for javascript)
