If you don't know what is Cryptpad, see here. It is a very cool project but I don't like the UI. However, the team offers the possibility to customize the Look and Feel of the app, so here we go ! To install it, simply copy the content of customize into your root cryptpad installation, then restart service. If you don't like the theme, simply remove the folder and restart.
I am not an expert in CSS, so the code is perfectible. But keep in mind that the main contrainst is that I choose to not modify the html files, the structure. I edited only the .less files.
The folowwing have been taken with default blue theme activated and Dark theme enabled. Be assured, it works in the same way with the others colors and theme.
