Hi @Manazd,
first of all, thanks for your first contribution to this project! 🎉 👍 🏅
I hope you'll like this project and enjoy hacking on it… 😃

BTW you can (automatically) let issues close when a PR is merged by adding some "magic" text to your PR body. (Manually linked it now.)

Thanks a lot for this PR, however, as it affects all add-ons I guess it would likely be good to have that source code in https://github.com/TinyWebEx/CommonCss/blob/57cd712256ae06a424b550521aabfbd855cfb4e3/common.css#L51 directly.

Also, do you have some screenshots to show how it looks? For visual changes that is always appreciated to easily have an idea how sth. looks.
