## Description

Sometimes websites don't look the way you want them to. Simplify or change them with Cascading Style Sheets. CSS can be applied to many pages with the * wildcard. It is applied before the HTML loads. The CSS is edited in a popup window or the big options page, not in a sidebar of the page; you are not hindered by the page.

Features:
 • Edit CSS: View & edit styling for one page or many
 • Storage Sync: Options saved for use on any computer
 
Instructions: Configure Keyboard Shortcut:
1. Click the icon for this extension
2. Click "Keyboard shortcuts"
3. Make a keyboard shortcut for "Big options page: edit site"
4. In the future, use this shortcut so you can use "Inspect Element"

Instructions: Add Site:
1. Open the popup or big options page
2. Go to the field "Add site"
3. Type in a URL like the following
 • Normal: en.wikipedia.org
 • Wildcard: *.wikipedia.org or *
4. Hit enter or click the plus button

Instructions: Edit CSS
1. Open the popup or big options page
2. Add rules and change properties
3. Refresh the site
