I've been developing a theme on rtPanel for the past few days, and actually I came across this issue.
I use a background image in the body which will repeat to the x-direction which has a height of 275px. Now this image will serve as the BG for my header till navbar, also the image spreads 100% throughout the screen.
Now in the footer I want to add something similar(BG image), which fill spread through out the screen which should begin before the footer widget.
One possibility I could think of is use 100% width for the
main-wrapper ID, but as it is already defined as 960 px, issue arises. Also I wont be able to add any element before the main-wrapper ID using hooks, as
rtp_hook_before_header(); is loaded after the
header-wrapper element. Any suggestions on tackling this?
