Safari 3 supports RGBA values whereas the cited versions of Mozilla 
Firefox and Opera do not. Development versions of all those browsers 
/do/ support RGBA values, however.

Also, note that the /top/ box is not missing; I believe that you refer 
to the invisible /bottom/ box.

Windows Internet Explorer 7 does not support RGBA values. Additionally, 
WIE lacks support for XHTML including the XHTML MIME type and file 
extensions. Insofar as I know, none of these features are supported in 
development versions of that browser either,

Summary: Three of the four browsers that you tested don’t meet the 
requirements for the test.
