Syntax for if/else condition in SCSS mixin

Question

Hi I\'m trying to learn SASS/SCSS and am trying to refactor my own mixin for clearfix

what I\'d like is for the mixin to be based on whether I pass the mixin a width

Answer 1

You could try this:

$width:auto;
@mixin clearfix($width) {

   @if $width == 'auto' {

    // if width is not passed, or empty do this

   } @else {
        display: inline-block;
        width: $width;
   }
}

I'm not sure of your intended result, but setting a default value should return false.
