Should anyone share how to make the x'mas background?
Hello Weiyan, and thank you for your kind feedback.
The background image near the footer is a combination of our xenfans backdrop with a cut out from an existing wallpaper, and a few other things to make it all work. We focus the background with css to the bottom and make it stretch 100% - a gradient in the background near the top will allow it to blend into the real background color that is underneath it. The header itself is another image that I made, and used from a quick search on images.google and photoshopped to be suitable for xenforo, with a gradient icy finish at the bottom that blends into the background again. All in all it looks as 1 big background image with the forum on top.
a lot of improvements can be done to it but i am pleased with the simplicity of it which gives it a user-friendly look.
It's a unique look to our web site, and we want to keep it that way, so we're not allowing others to use our images - I hope you understand. But .. it's a great inspiration for others to make their own photoshops and create unique and innovating backgrounds.
