Astyle is a CSS editor, that allows you to design style sheet (CSS) code from a visual interface without the need for any code typing. It comes with a preview that shows you how each element will be displayed in the browser. The style sheet values and properties can be selected from a grouped list, using simple checkboxes. The program displays the style sheet in an easy to read property tree with icons for each property, and options to add comments or mark specific properties. The interface a little confusing and difficult to use.
