Sass
Sass (short for Syntactically Awesome Style Sheets) is a preprocessor scripting language that is interpreted or compiled into Cascading Style Sheets (CSS).
Sass exists in 2 syntax variants:
- The original syntax, called "the indented syntax," uses indentation to separate code blocks and newline characters to separate rules.
- The newer syntax, "SCSS" (Sassy CSS), uses block formatting like that of CSS. It uses braces to denote code blocks and semicolons to separate rules within a block.
The indented syntax and SCSS files are traditionally given the extensions .sass and .scss, respectively.
