title: Flow Control Rules
|

|
Sass provides a number of at-rules that make it possible to control whether
|
||
|
|
styles get emitted, or to emit them multiple times with small variations. They
|
||
|
|
can also be used in [mixins][] and [functions][] to write small algorithms to
|
||
|
|
make writing your Sass easier.
|
||
|
|
|
||
|
|
[mixins]: mixin
|
||
|
|
[functions]: function
|
||
|
|
|
||
|
|
Sass supports four flow control rules:
|
||
|
|
|
||
|
|
* [`@if`](control/if) controls whether or not a block is evaluated.
|
||
|
|
* [`@each`](control/each) evaluates a block for each element in a [list][] or
|
||
|
|
each pair in a [map][].
|
||
|
|
* [`@for`](control/for) evaluates a block a certain number of times.
|
||
|
|
* [`@while`](control/while) evaluates a block until a certain condition is met.

[list]: ../values/lists
|

|
|
[map]: ../values/maps
