Gridth

User CSS

An extension for Safari 5 to Safari 11 that allows the user to override stylesheets for any web page with real-time updating of web pages. It is no longer maintained due to deprecation of JavaScript-based extensions in Safari 12.

The extension is licensed under the MIT license.

Downloads

Note

Due to a limitation with Safari’s URL parsing, domain wildcard only works for subdomains. For example, http://*.google.* will not work. You must use http://*.google.com/*

Database for User CSS is stored at ~/Library/Safari/LocalStorage. You can access this directory by pressing Cmd-Shift-G in Finder. The database file is named safari-extension_com.gridth.usercss-v892bvzc73_0.localstorage
