What is Custom Style Script?
Custom Style Script is an Edge add-on that enables users to redefine the looks or behaviors of a webpage. This is achieved by letting the users add their own JavaScript or CSS codes. The add-on offers flexibility as it allows users to choose where to apply the codes - on certain pages or all pages. Furthermore, each entered code has adjustable options promoting user personalization. The add-on also supports adding online JS or CSS links. Prior to insertion, codes should be validated to ensure their correctness and prevent errors.

There's no ability to filter the URL based on 'starts with', basic wildcards nor regular expressions. You can only filter on: * Domain name * Exact URL * Any URL (by inserting the string '*'). For me, this limitation makes the extension virtually useless for simple CSS injection. Instead, I'd need to write my own JavaScript, which negates half the point of this extension - hence half the star rating.
