I hadn’t heard there was support for calc() in css yet, but apparently you can use it in a couple browsers! This is very exciting news and I wonder how long until it’s fully supported. Currently it can be used in the chrome 19 (with vendor prefix: -webkit-calc), firefox since ff8 (with the vendor prefix: -moz-calc) and the biggest surprise of all is that IE9 supports it already with no prefix! It seems css will begin contending with some of the css preprocessors.
