All themes and screenshots have been redone on Nov 2025. They are now also switchable by clicking the paintbrush icon on the top-left corner. This functionality requires JavaScript to be enabled. Turning it off will simply use the default theme and not affect any other functionality.
If you don't want to enable JS, you'll need the Stylus extension to apply custom themes. Click on one of the theme's screenshots and copy the resulting CSS. Then, click the Stylus extension icon and Write style for: digdeeper.love
. Paste and save. Give it a name that will remind you of it. You can add all the styles I've created and switch between them at will from the Stylus menu. Sometimes I modify them, so the screenshots might not be perfect representations forever. And you will need to update your style extension to see the changes.
