How many syntax's that sass support?

The Sass has supported two syntaxes which are Indented (sass) and scss.

• Indented (sass) syntax:

The semicolon and curly bracket remove and add a colon before every property tag.

classname 
:color pink

The scss syntax is the same as a CSS syntax with its own modification.

}
