I'm trying to get a full page background image up working on my site by following the CSS3 method in this post here. When I go to edit my CSS in custom design, I enter the background-size CSS3 property and it's value. When I click save, it removes that property from the custom CSS area. Is there a reason why this wouldn't be saving?
Any advice/help would be appreciated before I contact WordPress support.
The blog I need help with is grantnovey.com.
