CSP U4 Photo Liker

Trying to add a font change and background color update to the photo liker. Kind of mixing the quote maker and photo liker together. I keep getting a warning, and I’m not sure what to do about it. Here are a couple of screenshots. Any help debugging would be awesome.

Please provide a link to the project. It is difficult to look at screenshots and debug.

Thank you for your help.

Set the background-color variable to some default value when you are defining it on line 5. When the font is changed, it tries to also change the background-color, but no color is defined.
