"Live CSS will monitor <link> tags on the page and poll the server for changes to the CSS. When there are changes, the page's styles get updated. It's a simple tool, and it's immensely powerful because it enables the One True Workflow we've all lusted after: to have your browser and your editor side by side on screen and watch the page update in real time as you type in your CSS files. It looks like magic." - Amit Patel from Bookmarklet
