A handy utility to replace Chrome's removed 'Custom.css' functionality.
In version 32 of Chrome, Google removed the ability for users to define their own styles for websites via the 'Custom.css' stylesheet. This extension fixes that, and adds to Custom.css's functionality.
Unlike in Custom.css where styles are applied to every web page, Injector applies styles based on the domain of the website, meaning that, say, styles for YouTube's player won't affect the player on Twitch.tv.
Injector is also open source and licensed under GNU Affero GPL, meaning you're free to download it and modify it. The code is available on GitHub, and anyone can submit pull requests to add features to the extension.
