Introduction to LESS language

The LESS language is an add-on to the CSS language, adding additional features to it that make work easier.

Technically, LESS is a preprocessor. This means that you will write code in the LESS language, and a special program will transform this code into the CSS language, and you will include the result of the transformation in the HTML file.

To convert the code, special programs compilers are used. There are quite a few such programs and you can choose one of them to your taste. To begin with, I suggest you use one of the following programs: Koala or Prepros.
