How about simply use a browser extension? Something such as: https://addons.mozilla.org/en-US/firefox/addon/darkreader/

Same thing exists for Chrome: https://chrome.google.com/webstore/detail/dark-reader/eimadpbcbfnmbkopoojfekhnkhdbieeh

If you're using Edge or I.E. then there is no helping you. :P
