SASS language syntax

SASS script can be specified in two types of syntax

  • SCSS syntax
  • Indented Syntax

SCSS Syntax

scss is a superset of CSS, every style in CSS is valid in scss. the file extension is scss It uses brackets for blocks or functions, semicolons for end of line

$margin: 2px;

.leftsidenavigation {
  background-color: $color;

.rightsidenavigation {
  margin: $margin * 2; 

end of the line contains a semicolon, block, or multiple statements enclosed in brackets.

Indented Syntax in SASS

The file extension is sass

Instead of brackets, It uses indentation

SASS example


  background-color: $color

  margin: $margin * 2

When compiled SASS/SCSS files, generated CSS output is

.leftsidenavigation {
  background-color: red;
  padding: 5px;

.rightsidenavigation {
  margin: 4px;

Difference between SASS and SCSS

Extension is SCSS Extension is SASS
Each line is ended by a semicolon Semicolon is not required, just include line break
Block of styles are enclosed in brackets block of styles are indentation by spaces
