Forum:Background help

I was using the Theme Designer to upload my own background on my Wiki. I need help with a CSS expert to make my background a custom graphic with 300px side rails. The left side of my background appeared, but the right side didn't appeared.

This is my background i wanna use




 * Why do you need a CSS expert? Why not just upload the file through ThemeDesigner?  21:41: Tue 15 May 2012
 * Your issue has nothing to do with CSS. The right side isn't showing up because your dimensions are wrong. You've got far too narrow a gap between the two sides of the pic, meaning that your right side is almost certainly under the main text area of the wiki.  Your gap alone must be 1000px exactly for it to work out.  Your entire picture's width is 1000px.  It's not gonna work out.  You need to go back to Photoshop, not worry about CSS.  21:48: Tue 15 May 2012


 * Thanks, but i know it has nothing to do with CSS. I meant that i need help with somebody
