SCSS
/ɛs siː ɛs ɛs/ · Abbreviation · Development
Definitions
Sassy CSS — the newer, CSS-superset syntax of the Sass preprocessor that uses curly braces and semicolons (unlike the indentation-based `.sass` syntax), adding variables, nesting, mixins, and functions that compile down to standard CSS.
In plain English: An extended version of CSS that lets you use variables, nesting, and reusable snippets, which then gets converted into regular CSS.
Example: "We migrated from plain CSS to SCSS so we could use variables and nested selectors without changing our existing files much."
