Ok, so I can't find anything about this.
I know it is horrible to change the scroll speed of a site, but I need to do this for a site which is more a game than a site.
Can someone tell me how to slow down de scrollspeed? Jquery or css?
EDIT: I want to change the scrollspeed whem people scroll with the mouse wheel.
