Correct some CSS Error in a JustUno Pop-Up

This is a VERY easy job for someone that knows CSS well. *Please Read* you will also have to make yourself familiar with the CSS structure of JustUno ([login to view URL]) if you aren't familiar already. We will NOT provide you support for that as that is why we are hiring a CSS expert. The issue is very simple, I can provide you the Custom CSS code we are using to edit how the Pop-up looks, and you can Fix and use that code, or use your own custom code (whichever is easiest for you) to make the Pop-up look like the picture I am attaching on here. We already have the images *you do NOT have to design them* however there is an error in the CSS code that is preventing the "Offer" text from showing, and we need to have that corrected. It should be as easy as editing a few lines of CSS however we do not know which ones need to be edited.
