Sass #css
Sass (Syntactically Awesome Stylesheets) is a preprocessor scripting language that is interpreted or compiled into Cascading Style Sheets (CSS). SassScript is the scripting language itself. Sass consists of two syntaxes: the original indented syntax called "Sass" and the newer "SCSS" (Sassy CSS).
