facebook like box background

Hi,
I have 2 facebook like boxes, 1 in the sidebar with a white background and one in the footer with a yellow background.
I’ve added this css to make the footer facebook widget background yellow:

.av_facebook_widget_wrap {
background:#fcebb8!important;
}
But it makes the background of the other widget yellow too.
I’ve tried adding this css to tell the sidebar widget to keep its white background but it makes the footer widget background white again.

section#avia_fb_likebox-6.widget.clearfix.avia_fb_likebox.av_facebook_widget_wrap {
background:#ffffff!important;
}

I’ve also tried:

section#avia_fb_likebox-6 {
background:#ffffff!important;
}
section#avia_fb_likebox-5 {
background:#fcebb8!important;
}
But no luck…

Is there any way to have two different backgrounds for the same widget in a different location?
Thanks,
Lisa
