Up and running with installing Less for CSS on OSX
Less is a CSS pre-processor tool in which you initially write your CSS code using variables, selector inheritance, mixins, and nestings and and then compile that code to spit out regular CSS. The benefits of using CSS pre-processor tools like Less or Sass are more advantageous on larger web projects with big CSS code bases – these benefits include quicker code updates across the codebase using variables.
