This userstyle is aimed to theme most sites you visit with dark colors. It doesn’t work flawlessly on every site, nor does it intend to do so (it’s impossible to make a style look good in every page with general rules), the main purpose is to just darken most sites you don’t frequently visit (and thus finding specific userstyles for each one would be cumbersome apart from very inefficient) with an all-around dark style. This same principle applies to all global styles.


For pages that you DO visit frequently, you should use a site-specific style instead, not only for better compatibility, but also for better visuals.

You can find how to add exclusions to the global style here.
