Sass is a CSS extension language that adds features such as variables, nesting, mixins and more.
Sass (and other preprocessors, such as [Less](http://lesscss.org/)) help developers to write maintainable and DRY (Don't Repeat Yourself) code.
Sass (and other preprocessors, such as [Less](http://lesscss.org/)) help developers write maintainable and DRY (Don't Repeat Yourself) code.
Sass has two different syntax options to choose from. SCSS, which has the same syntax as CSS but with the added features of Sass. Or Sass (the original syntax), which uses indentation rather than curly braces and semicolons.
This tutorial is written using SCSS.
If you're already familiar with CSS3, you'll be able to pick up Sass relatively quickly. It does not provide any new styling options but rather the tools to write your CSS more efficiently and make maintenance much easier.

## SASS or Sass?
Have you ever wondered whether Sass is an acronym or not? You probably haven't, but I'll tell you anyway. The name of the language is a word, "Sass", and not an acronym.
Because people were constantly writing it as "SASS", the creator of the language jokingly called it "Syntactically Awesome StyleSheets".

## Compatibility
Sass can be used in any project as long as you have a program to compile it
into CSS. You'll want to verify that the CSS you're using is compatible
with your target browsers.
