eCSStender is an open source JavaScript library, created by Aaron Gustafson, that aims to prevent the usage of browser-specific properties and hacks but make lean and mean CSS possible. Extensions built with eCSStender greatly simplify the design process because you can author modern CSS using advanced selectors, properties such as border-radius, or custom font faces and rest assured that your design will work. To use the extensions, download eCSStender and include it and your extensions in your sites. For more information on the eCSStender API, make sure to consult the documentation.
