    Sass @each Loops

    While we believe that this content benefits our community, we have not yet thoroughly reviewed it. If you have any suggestions for improvements, please let us know by clicking the “report an issue“ button at the bottom of the tutorial.

    If you’ve got a Sass Map or Lists you can loop through them, rather than addressing each key separately. At the beginning of the @each loop, you assign a variable to be used inside the loop:

    $shapes: triangle, square, circle;
    
    @each $shape in $shapes {
      .icon-#{$shape} {
        background-image: url('/images/#{$shape}.jpg');
      }
    }
    
    $map: (
      h1: 20px,
      h2: 16px,
      h3: 14px
    );
    
    @each $element, $size in $map {
      #{$element} {
        font-size: $size;
      }
    }
    

    If concatenating the variable with a string, or using it as a class/element, the variable will need to be preceded with a #{ and prepended with a } to tell the compiler you actually mean the variable.

    You are also able to nest loops inside of loops, if your map is multi levels deep.
