User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:1.8.0.7) Gecko/20060913 Fedora/1.5.0.7-1.fc5 Firefox/1.5.0.7 pango-text

if you use the c++ comment "//" in CSS then firefox/seamonkey accepts that as a comment and ignores the rest of the line.

this appears to be outside of any CSS spec i can find and also entirely undocumented.

Reproducible: Always

Steps to Reproduce:
1.have a look at the URL
2.have a look at the source
3.have a look at the results

Actual Results:  
got a red box.

Expected Results:  
get a blue box.

i tried this is this version of firefox and seamonkey.

If you look closely enough, you'll note that it's not ignoring the whole line but only the background color related rule (otherwise the text would be yellow and not white). A look into the Error Console confirms:

Warning: Expected declaration but found '/'.  Skipped to next declaration.

Line: 8

You happen to have encountered rather a parsing bug in IE. BTW: Opera and Safari both render the page as Firefox does...

okay.  thanks for pointing this out.

should there be some indication on the screen that an error has been seen?  i wasn't aware of this 'error console'.  (i've found it in seamonkey now - i guess it's an extension in ff.  3 errors and 3 warnings, apparently!)

so, uh, where do i go to report IE bugs?  ;-)
