Project Name

CSS Checker Add-on SDK Extension 0.3

Project Description

CSS as a standard evolves more slowly than browser vendor implementations, and as such, browser extensions are created. For example: -moz-box-shadow (Mozilla only), -webkit-box-shadow (Chrome/Safari), box-shadow (CSS standard). This extension will allow the user to tell when a a -webkit-* extension is being used for which there is also a -moz-* version. This will help with finding compatibility issues on websites that appear to work in one browser and not another.
