Removing ALL Profile 2.0 Background Colors
note: codes goes into your "advanced CSS" box under "Customize Profile"
This will remove all the background colors, but leaves the borders around the sections.
If you also want the borders and lines removed, then use this instead.
The part that is "behind" the modules - this will make that white area transparent so you can see your background image through it.
If you want ALL of the modules to be transparent, so that you can see your complete background image, use this.
