Hi, I am interested in changing the color of a button within a frame on Google Docs, one that is provided by an extension to Docs, Paperpile. I can inspect the element in Chrome and change the color there, but of course it doesn't stick. When I cut and paste the CSS into Stylish, it fails because the button is referenced by a name that Stylish doesn't have access to. I am not sure how to proceed and would appreciate any tips. How much CSS do I need to provide? If I could get access to all of it, I would include it, but I'm not sure how to do that either.
