Hello!
Tried everything... :/
I managed to insert a (general) background image (.jpg or pattern with repeat) that fills all the body, but i can't figure out how to insert a second background-image above (a .png, that's transparency shows the jpg-body-background, position: for example inside header).
code for the body-background:body {
background-color:#333 !important; background-image:url(/images/darktex.jpg) !important;background-position: center top !important; background-repeat:no-repeat !important;}
I tried to insert the second background-image the same way inside header / rt-top-surround, but it doesn't work yet.
bad code:#rt-top-surround {
background-image:url(/images/eq-bg.png) !important;background-position: center top !important; background-repeat:no-repeat !important;}
Any hints please?
Thx in advance!
