CSS Errors in FireFox Web Developer

[Website Rob]

Is programming a clean site possible or is it something to strive for but never really get there?

Coding for a clean site is definitely possible and what good coders always strive for. Why do you think a clean install of Zen Cart is error free for the HTML & PHP coding? Good coding by people paying attention to their coding is why. This is also the starting point for using correct code to provide various levels of script security.

The trick in coding, is to know the meaning of the errors / warnings, what they are about and their level of severity. Some can be safely ignored whilst some should be corrected.

In your case, I think it is safe to say you can ignore the Warnings and move on to other things.

I noticed that my site is having parsing problems when viewing in Firefox (IE is fine). I experience delayed loading time when clicking the individual products from category pages. The Firefox Web Developer error console list the following errors:

Warning: Error in parsing value for property 'font'. Declaration dropped.
Source File: http://www.all4coffee.com/includes/t...icimghover.css
Line: 58
Warning: Unknown property 'behavior'. Declaration dropped.
Source File: http://www.all4coffee.com/includes/t...eader_menu.css
Line: 2
Warning: Error in parsing value for property 'font'. Declaration dropped.
Source File: http://www.all4coffee.com/includes/t...icimghover.css
Line: 58

Would anybody have any ideas how to fix this?
