What’s the difference between SCSS and Sass?
There are two syntaxes available for Sass. The first, known as SCSS (Sassy CSS) and used throughout this reference, is an extension of the syntax of CSS. This means that every valid CSS stylesheet is a valid SCSS file with the same meaning. In addition, SCSS understands most CSS hacks and vendor-specific syntax, such as IE’s old
filter syntax. This syntax is enhanced with the Sass features described below. Files using this syntax have the
The second and older syntax, known as the indented syntax (or sometimes just “Sass”), provides a more concise way of writing CSS. It uses indentation rather than brackets to indicate nesting of selectors, and newlines rather than semicolons to separate properties. Some people find this to be easier to read and quicker to write than SCSS. The indented syntax has all the same features, although some of them have slightly different syntax; this is described in the indented syntax reference. Files using this syntax have the
Either syntax can import files written in the other. Files can be automatically converted from one syntax to the other using the
sass-convert command line tool:
# Convert Sass to SCSS
$ sass-convert style.sass style.scss
# Convert SCSS to Sass
$ sass-convert style.scss style.sass
Note that this command does not generate CSS files. For that, use the
sass command described elsewhere.
