If/Else Statements in Sass

An if statement is handy for checking if a variable exists or matches something:

$var: true !default; // Can be overridden elsewhere

@if $var == true {
  // Conditional code
}

$other: single;

@if $other == single {
  // Code for if it’s single
} @else if $other == double {
  // Double code
} @else {
  // Default if it’s neither
}

Make sure that if your variable properties are stored with ’ quotes around them, your @if statement checks that too. (e.g. $other ==‘single’).

if statements can be useful for mixins for checking variables or in libraries to include or exclude code.
