title: Plain CSS Functions
|

|

|
||
|
|
|
||
|
|
Any function call that's not either a [built-in][] or [user-defined][] function
|
||
|
|
is compiled to a plain CSS function (unless it uses [Sass argument syntax][]).
|
||
|
|
The arguments will be compiled to CSS and included as-is in the function call.
|
||
|
|
This ensures that Sass supports all CSS functions without needing to release new
|
||
|
|
versions every time a new one is added.
|
||
|

|

|

[built-in]: ../functions
|
||
|
|
[user-defined]: ../at-rules/function
|
||
|
|
[Sass argument syntax]: ../at-rules/function#arguments

Because any unknown function will be compiled to CSS, it's easy to miss when you
|
||
|
|
typo a function name. Consider running a [CSS linter][] on your stylesheet's
|
||
|
|
output to be notified when this happens!
|
||
|

|

|

[CSS linter]: https://stylelint.io/

|
|
Some CSS functions, like `calc()` and `element()` have unusual syntax. Sass
|
||
|
|
[parses these functions specially][] as [unquoted strings][].

||
|

||
|
|
[parses these functions specially]: ../syntax/special-functions
|
||
|
|
[unquoted strings]: ../values/strings#unquoted
