How to get Dark Mode / Night Mode on Websites?
The Dark Reader
Dark Mode may be one of the most-wanted features from users, but not all apps and websites offer it natively.
However, this third-party browser-extension can enable the functionality across most websites, including Google Search, Twitch and more.

The ‘Dark Reader’ Browser Extension Enables Dark Mode on All Websites. It is free and open-source extension/add-on is available for a number of web browsers, including Google Chrome, Firefox and Safari.
According to its official listing, it claims to offer a Dark Mode for ‘every’ website and allows users to adjust brightness, contrast, sepia filter, dark mode, font settings and ignore-list.
What’s more, it’s an ad-free software without any data-mining script, and its full source-code is available on Github.
