    What is LESS?

    LESS is a CSS preprocessor that allows for variables, nested rules, mixins, and more, making your stylesheets more efficient and maintainable.

    LESS code:

       @global_color: #FF0000;
   @global_font_size: 14px;
   @secondary_color: #CCC;

   body {
      color: @global_color;
      font-size: @global_font_size;
   }
   .container {
      color: @secondary_color;
      font-size: @global_font_size * 2;
   }

    Outputs the following CSS:

       body {
      color: #FF0000;
      font-size: 14px;
   }
   .container {
      color: #CCC;
      font-size: 24px;
   }
