With this picture you can have the effect of animated snow on the branding space, that is across the line of the logo.

How-to:

STEP 1:
load the image .gif folder in the folder of your skin, public / style_images / yourskinskin

STEP 2:
ACP> Look & Feel> Manage Skin Sets & Templates> Choose your skin> CSS> ipb_style.css
Find branding_bg (and copy the code to then be able to recover once the Christmas season is end) and replace the background with the line:

   background: #558525 url(http://www.devfuse.com/forums/public/style_images/master/branding_snow_tr.gif) repeat-x;

# 558525 is the background color (green in this example) (do not use too bright colors because the white flakes of snow are not seen)
