LOVE this widget - and was able to get this working in no time!
However, I am having a problem with the background color on the front page of my site. I read the post Widget background color (Twenty Thirteen theme) and tried your suggestions - my theme is made in Artisteer though. But still no luck.
I have limited the widget to only appear on the front page - which is a static Page.
I can tell you that the background color worked on all the other pages and posts - just not the front page for some reason.
Any suggestions would be greatly appreciated.
