Couldn't change background-color to 'main'?

I'm not sure if I'm the only one, but my FF or Safari is showing different background color for the Main section (that holds all the Blocks), but it displays correct in IE. So, trying to change in the ''common.css' I couldt find the 'main' section like D6 used to have. Anyone knows how to change the background-color surrounding the Blocks (not within the Blocks)? thx

common.css right on top

body {
font-family:Verdana,Arial;
font-size:11px;
color:#333333;
background-color:#ffffff;
margin:0px;
padding:0 0 50px 0;   
}

Prolaznik, if you change the values for the body and test it, it will change the color of the whole body outside the Box that holds all the Blocks. I want the color of the background that hold the Blocks, not the Body. Thanks for your reply though. Is your showing the same color in FF and IE?

Background for the div section that holds the blocks is in general.css

deano, I tried that .main in general.css but didn't change the background of the div that hold all the Blocks (it changes only part of the top section). Which means I couldnt even change that div bkgrd at all (tried so many places in common.css and general.css). Now, I don't have any mods or templates. This is a clean D7 install. So, my question is why is it not white bkground for Safari or FF like IE? Can anyone confirm on your end, pls? May be something is wrong on mine.

I do this sort of stuff all the time. It works.

PM me your site url. Shut off CSS caching from admin and tell me what your trying to do EXACTLY, and i can tell you how to do it. This should be simple.

Okay I and I think zak2008  are trying  to change the color of the blueish/grey background behind the "article content" as seen here the main bckgrnd & box background are FFFFFF  but cannot find backgrnd for body content
