Whilst it’s not just by style.css, the theme currently being developed as a community project for the next version of BuddyPress has a background and colour function that you may be able to use as a template to do something like you want. It’s open source so feel free to download from github and take whatever you want into your theme.

A word of caution though that theme is in beta currently.

thanks this theme looks great, i test it out just to try it out but some how the background image/background color/ color links dont seem to work? at all.. im running buddypress 1.5.5 and wordpress 3.3 but it seems the theme works great no fatal errors nothing which i think its weird also another thing i wanted to ask you is there a way i can easily show the background color/ background image in different parts of the profile example like in the profile header box like below
`
body.user-profile-header{
background:();
}
`
@mercime
i have surely looked into that but for me its hard to add color picker functionally and stuff and set user id sava data so its best to have a live sample already created so i can start from it and tweak it,
but either way thanks for the help.
@karmatosed
nvm i got it working now. thanks ill see what i can do with it. i appreciate your help!
