You probably have heard of LESS, Sass, Stylus, and others but may not have had a chance yet to figure them out. Here’s a very brief overview…
Why should you be using one of these?

- Retain browser compatibility
- Allow for the creation of variables using reusable CSS properties
- Allow for better code by making it more scalable and modular
- Introduce parent references, math, mixins, nesting, and error reporting
Which one should you use?
There is no bad choice. Like with anything else in programming other factors are the drivers here. Do you use Ruby? Then you will probably gravitate towards Sass. Are you a heavy Bootstrap user? Then consider looking at LESS or Stylus… Research and see which works for you.

Sass makes CSS fun again. Sass is an extension of CSS3, adding nested rules, variables,mixins, selector inheritance, and more. It’s translated to well-formatted, standard CSS using the command line tool or a web-framework plugin. Sass has two syntaxes. The most commonly used syntax is known as “SCSS” (for “Sassy CSS”), and is a superset of CSS3’s syntax. This means that every valid CSS3 stylesheet is valid SCSS as well. SCSS files use the extension
