[xwiki-users] Stop the edit/export/more actions bar from moving

I don't consider myself an expert at CSS, but I can usually manage anything I need. However, I cannot figure out how to stop the contentmenu bar (has the edit, export, and more actions dropdown menus) from staying put over the content area as I scroll down the page. I'm sure this is probably ridiculously easy to change and is something I'm overlooking, but I'd appreciate the help. If anyone wonders why I want to in the first place, I'm trying to decrease the width of the wiki to the same size as our other webapp (to make them look the same), and when I do, the bar skews over out of place when you scroll down. We don't need the bar to stay in place as a person scrolls anyway, so I'd like to just turn that off. Thanks for any help, Lenny
