How does one make their own custom theme using Stylus?
Do you mean a custom Derpibooru theme that recolors everything appropriately? Hours and hours of CSS fiddling.
However, you can make simple style changes without too much work if you know some CSS. Click on the Stylus button and pick an option from Write new style to experiment with.
I should use this to remind myself how much of a Mac addict I am even when I’m running a GNU+Linux desktop. This is the theme to repel those Windows 🪟 users.
All the themes have been updated to work with the various “alt” boorus out there, so you can enjoy a consistent experience between boorus wherever you go.
Only other change is to fix sparkline colours on user profiles.
