Made a Mailspring Theme based on "Materia-Black-Colors"

Having learned that you theme Mailspring with Cascading Style Sheets, I figured that fits in nicely with my Hyprland tinkering so, I’m giving it a shot.

Not the first theme I put together for Mailspring, but my first time trying to upload it to GitHub. Should be right but let me know if it’s not.


Nice I don’t use mailspring but always nice seeing others sharing their customisations so others can try them out
