MyBB Community Forums

Hello. I have added a background image to my forums. I've centered it and made sure it doesn't repeat, but it's just sitting in the middle of the page. I want it to cover the whole page, so when you scroll up and down the only background you see is the one I've added.
Take a look at what I mean: http://www.timburtonforum.co.uk/forum
You can see the black background above and below the image I have added but I don't want users to see that. I just want the image visible.
Please help.

Not really sure if I got what you mean but try adding

background-attachment: fixed;

to the background style.
