Quickly and conveniently restyle any web page in Safari

Quickstyle is a Safari extension to change the appearance of any web page by adding your own CSS rules to it. Quickstyle features a convenient “selector helper” that eases the task of finding the right CSS selector for the rule you want to create, and a built-in stylesheet editor so you can create and edit your rules right on the page. It’s a lot easier and faster than using Safari’s Web Inspector and editing an external User CSS file.
