Too often in my web development past I have found myself wading through huge clumsy CSS files of several hundred lines or more, searching for that place where a particular class is defined or to try and identify what it is that is overriding something else. It can be quite a nightmare. However I recently came across .Less (pronounced "dot-less"), a port of the great Ruby Less library for .NET. This is a brilliantly simple-to-use solution to an often-painful situation.
