I am playing around with a responsive wordpress theme based on the skeleton and have hit an annoying problem. A thin blue horizontal bar has appeared at the top of the screen, it can’t be anymore than about 15-18px height and has absolute positioning because it stay at the top of the page even when you scroll down. I’ve used both chrome and firefox (with firebug) to find out where it has come from but to no avail, it’s not showing in the css or the source code. Has anyone else experienced this or know why this is happening?
N.B. It appears in all browsers IE, Chrome & FF.

The blue background you are seeing is from your css, You probably have this:
in your body style, so just find it and remove it, and you’re good to go.
