Dark Mode for Websites That Ignore System Preferences
person Patrick Bushe · calendar_today April 10, 2026
Some websites hardcode their #FFFFFF (white) backgrounds into their HTML, completely ignoring whether your macOS or Windows system is set to dark mode.
For websites that ignore system preferences, client-side intervention is necessary. You can use Modern Dark Mode to force compliance. This tool operates at a higher CSS specificity level than the website's original code, injecting !important tags on background elements. This guarantees that no matter how stubbornly a website is coded to be bright, the extension will overpower it and render a soothing dark palette.
