## Description

This extension was created to be fast, simple, and unobtrusive: an easy tool for curating your web experience, whether you want to make accessibility adjustments to help you read your favorite text content, give a site’s dull color scheme some life, or simply hide page elements you don’t use.

Hit a button to start editing a page: changes made to a webpage can generalize to other pages on the same site. Then, right click on something and start changing it! Your changes will be saved locally in your browser's local storage for that website; you can also export the CSS you've generated and import it at any time.

While you can import more exhaustive stylesheets, this extension's primary goal is simplicity and ease of access. Its customization options were selected for being individually powerful, and their presentation in the editor, intuitive. This way, you can change the way websites look painlessly, without any CSS knowledge.

This extension was created as a solo undergraduate project.
