I'm having a bit of an issue, that really concerns me. The issue is, i want to have a custom background that looks correct on my site. However, although i have accomplished properly installing the custom background, i noticed the background size looks different on different computers, due to their different screen size, or resolution.
Is there a way to make the background a universal size, so to say? So that no matter what computer views the site, it will look correct. I noticed on Xenforo's main page, the background looks perfect on different computers, so if anyone knows how to help me please do so!
Thank you so much for your time.
