Sass (Syntactically Awesome Stylesheets) is a module included in Haml. Sass is a CSS-based metalanguage designed to increase the abstraction level of CSS code and simplify cascading style sheet files.

Answer 3

What is Less and Sass?

Answer 4

Let me explain in a simpler way:
CSS itself is boring, it implies the need to duplicate code and remember such data that you don’t need to keep in your head (HEX color codes, indents for different types of page elements, etc.).
SCSS and LESS solve the problem by adding variables, functions, hashes, and other convenience features to CSS. In addition, with a competent style architecture, you can very flexibly and conveniently manage the styles of individual components without having to search for a single line in a large, large file.
This is in short.

In my opinion, this is a necessary tool for a self-respecting coder.
