What's the difference between SCSS and Sass?

The Sass .sass file is visually different from .scss file, e.g.

Example.sass - sass is the older syntax

$color: red



=my-border($color)

  border: 1px solid $color



body

  background: $color

  +my-border(green)

Example.scss - sassy css is the new syntax as of Sass 3

$color: red;



@mixin my-border($color) {

  border: 1px solid $color;

}



body {

  background: $color;

  @include my-border(green);

}

Any valid CSS document can be converted to Sassy CSS (SCSS) simply by changing the extension from .css to .scss.

The difference is syntax. Underneath the textual exterior, they are identical. This is why sass and scss files can import each other. Actually, Sass has four syntax parsers: scss, sass, CSS, and less. All of these convert a different syntax into an Abstract Syntax Tree which is further processed into CSS output or even onto one of the other formats via the sass-convert tool.

Use the syntax you like the best, both are fully supported and you can change between them later if you change your mind.

Sass was the first one, and the syntax is a bit different. For example, including a mixin:

Sass: +mixinname()

Scss: @include mixinname()

Sass ignores curly brackets and semicolons and lay on nesting, which I found more useful.
