@return statement in SASS - Browser Rendering Trace

Render Flow - @return statement

Read @mixin or @function declaration

↓

Parse function body

↓

Encounter @return statement

↓

Evaluate expression after @return

↓

Exit function and pass value back

↓

Use returned value in calling context

The browser or compiler reads the function, evaluates the @return statement to get a value, then exits the function passing that value back to where it was called.

Common Confusions - 2 Topics

Why does my function not output anything if I forget @return?

Without @return, the function has no output value, so nothing replaces the function call in CSS.

💡 Always use @return inside @function to send back a value.

Can I have multiple @return statements in one function?

Only the first @return executed stops the function and returns its value; later @return statements are ignored.

💡 Place @return where you want the function to stop and output.

Property Reference

Keyword	Purpose	Usage	Effect
@return	Ends function execution	Used inside @function	Sends value back to caller
@function	Defines reusable code block	Wraps code with @return	Creates callable function
Function call	Invokes function	Used in property values	Replaces call with returned value

Concept Snapshot

@return statement in SASS functions ends the function and sends a value back. It must be inside an @function block. Without @return, functions output nothing. Only one @return is executed per function call. Use @return to create reusable values in stylesheets.
