title: Writing a loop that increments by a value other than 1 in Sass
body: <p>In SASS, a loop is written like so:</p>
  
  <pre><code>@for $i from 1 through 100 {
      //stuff
  }
  </code></pre>
  
  <p>This would yield 1, 2, 3, 4... all the way to 100.</p>
  
  <p>How would you make the loop go in intervals of two units?</p>
  
  <pre><code>@for $i from 1 through 100 *step 2*{
      //stuff
  }
  </code></pre>
  
  <p>So the result is 1, 3, 5, 7... to 99</p>
