+## styles.css
+
+styles can be used for custom element insertions, generally hiding/re-spacing elements,
+and particularly: colour theming.
+
+the enhancer has been designed with theming in mind, so as much of notion's colours
+and typography as possible (both for the light and dark themes) have been mapped out
+using css variables - check these out in the `mods/core/theme.css` and `mods/dark+/styles.css` files.
