CSS difference in browsers

CSS difference in browsers

Hi,
 
I came across a problem while checking the css attribute for the background-color.
Apparently it differs from browser to browser what the content is of this style.
 

  1. var

     bckColor = $(this).css("background-color");

    bckColor will be in IE #d19494 and in Firefox it is rgb(209, 148, 148).
The style tag of my element is <div style='background-color: #d19494'>. So if you would get as defined in the attribute tag it should be always the IE way.
If I do a view source I also see #d19494. But if I view the tag in FireBug I also see rgb(209, 148, 148).
 
Is there somebody awere of this?
Grtz
Steve
