About Custom Styles

This extension allows the creation of per-site stylesheets. After installing you can use the extension's options page to configure per-site CSS rules. Why use this instead of other extensions? - The content script used to inject CSS into sites is intentionally as simple as possible making it easy to audit that it is safe to use. It is only a few lines of non-minified script: https://github.com/flackr/custom-styles/blob/main/src/styler.js - Styles are automatically synced between devices using chrome's sync storage API.
