adding style css deletes closing curly bracket

I use image maps and I’ve always had success placing img {outline : none;} in the advance image box’s Style CSS to get rid of the blue borders that appear when you click a hot spot.

I noticed the blue borders were back, so I check the Style CSS and saw that the closing curly bracket ” } ” was missing from my code. I added it, saved it and tested the image map, but the closing bracket didn’t stick.

No matter how many times I try to enter the code, it keeps dropping that closing curly bracket so my CSS won’t work.

Has anyone experienced this? I’m stumped and really frustrated. My image map is at the bottom of the home page at
