I am using this simple code to adjust a full page background image to my element:
background: url(images/bg.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
Everything works great but now I have the problem that in Firefox V30 for example the background-image does not go to the left if the page shows a off-canvas panel from the right. The div which contains the background-image will of course be animated to the left but the background-image will not.
What are solutions to fix this issue?
