I had the tooltips showing up great editing the css in /events-calendar.css, but now it wont show up with the proper background color. It's now showing up a transparent, as if it's not reading the css. I haven't made any changes to the css since it's stopped working, so I think it has to be something else I've changed. Right now the only thing that will add any background to it is editing "TOOLTIPS FOR THE WIDGET" in ec-tooltips.css, but it doesnt cover the entire div. Any thoughts?
