You're done !


You can tweak your theme with somes options in the protonmail.scss file.

  • Easily change the color of this theme as you like with CSS vars.
  • $hide-navigation: Hide some navigation links you don't use that much (still accessibles on hover)
  • $hide-message-size: I personnaly don't use the size display for every message. If you need it just set the option to false.
