title: Convert Scss to Sass mixin
body: <p>I'm looking for some documentation on Mixins specifically for .Sass </p>
  
  <p>Not .Scss </p>
  
  <p>but due to the naming conventions they keep coming up with the same search results.</p>
  
  <pre><code>@function calculateRem($size) {
    $remSize: $size / 16px;
    @return $remSize * 1rem;
  }
  
  @mixin font-size($size) {
    font-size: $size;
    font-size: calculateRem($size);
  }
  </code></pre>
  
  <p><code>@mixin</code> becomes <code>=</code></p>
  
  <p>but further then this I don't know what <code>function</code> become etc....</p>
