<h1>Sass Syntax</h1>
<p>The Sass syntax is the original syntax. It is white-space dependent and doesn't require curly braces or semi-colons. A gotcha to keep in mind is that your tabbing has to be consistent. You can't mix spaces or tabs and the tab length should be consistent otherwise the compiler will eat flaming death.</p>

<div class="columns">
  <div class="col1">Column 1</div>
  <div class="col2">Column 2</div>
