This is a simple extension that allows you to toggle dark mode on any website. It uses the invert CSS filter to invert the colors of the website.
This is a simple way to get dark mode on any website, but it may not work perfectly on all websites.
The extension allows you to toggle dark mode on and off by clicking the extension icon in the browser toolbar or by using the keyboard shortcut Ctrl+Q. You can also set the extension to automatically enable dark mode on websites which seem to have a light color scheme. Moreover, you can invert the colors of single elements using the context menu to fix issues with websites that don't work well with the extension.
