My simple SCSS Cheatsheet

Using SCSS

Global Setup

Install on OS X: sudo gem install sass

CLI Usage

Version info: sass -v

Compile: sass styles.scss styles.css

Auto-Compile for single files: sass --watch styles.scss:styles.css

Auto-Compile for folders: sass --watch .

Notes

  • There is no difference between underscores and dashes in variables: $my_var === $my-var
  • Skip default spaces with a leading ampersand: &:hover
  • Skip default nesting with an ending ampersand body.blog &
  • Prevent compiling for @import with a leading underscore: _normalize.scss

Functions
