Customize

Settings

. - Customize the colors (or leave default).
- Enjoy!
You can customize the theme colors to your liking:
/* First paste any CSS theme. */ /* Now you can set your colors. */
The #xxx
value is hexidecimal color value. And the root
keyword is a CSS variable, that just sets the color values globally. These themes have been simplified to 7 "core" colors so you can easily make a custom color palette of your choice. You can also generate a pretty color palette from this site.
Enjoy!
Notes
- This is only available for the WEB version and not the MOBILE app.
- Some of these themes aren't always the best. If you have any problems you can open an issue here.
- If you're trying to use
@import
, the Content-Security-Policy (CSP) header blocks@import
statements from loading remote content. To get around this, please copy and paste the entire contents of the CSS theme rather than the@import
line.
Privacy and Performance
The above code used a CSS This is no longer a concern, now that the Content-Security-Policy (CSP) Header blocks import
statement for ease of use and quickly trying out a theme. However, the CSS import
statement causes files to load sequentially instead of parallel, thus slowing down your pages load performance. Also, if your privacy is of the utmost importance, then I wouldn't use the CSS import
statment from above. It potentially could reveal your behavior e.g. identifying when you load up ProtonMail using which specific theme. To avoid this, please copy & paste the entire contents of the CSS file, rather than use the import
statement.@import
statements from loading remote content.
