title: Zurb Foundation 4 SCSS mixins for small and large(fluid/responsive) columns
body: <p>I'm building a company responsive website and using both SASS and Foundation 4 CSS Framework for the first time. So far so good. 
  However I'm having a "problem" here with mixins. 
  If I want a column with size 6 in large views and size 3 in small views, I can use built-in CSS classes</p>
  
  <pre><code> class="large-6 small-3 columns"
  </code></pre>
  
  <p>Is there any way to do this via a Foundation SASS mixin? The only mixin for columns I found <a href="http://foundation.zurb.com/docs/components/grid.html">here</a> is </p>
  
  <pre><code>@include grid-column($columns, $last-column, $center, $offset, $push, $pull, $collapse, $float);
  </code></pre>
  
  <p>And for what I get, I cannot specify veiwports here.</p>
  
  <p>Any thoughts?
  Thank you in advance</p>
