WebPutty is a simple CSS editing and hosting service, which gives you a syntax-highlighting CSS editor you can use from anywhere, the power of SCSS and Compass, a side-by-side preview pane, and instant publishing with minification, compression, and automatic cache control.

You can see your changes instantly with the side-by-side preview pane, so there’s no need for the traditional back-and-forth between your editor and refreshing a browser to see your changes.

WebPutty also allows you to take advantage of SCSS and Compass. SCSS gives you expanded functionality and ease-of-use features like nested selectors, variables, and mixins, while Compass makes CSS3 features like box-shadow, border-radius, gradients, transforms, and transitions easier to implement by handling all the browser-specific prefixes for you.
