title: Apply CSS for a specific field on Formstack
body: <p>I was trying to span the checkbox field in 3 columns on this form - <a href="https://learningcurve.formstack.com/forms/list_of_banks" rel="nofollow noreferrer">https://learningcurve.formstack.com/forms/list_of_banks</a>\</p>
  
  <p>So, I wrote</p>
  
  <pre><code>.fsBody .fsForm .fsFieldCell {
      column-count:3;
  }
  </code></pre>
  
  <p>But it spans all the similar fields into 3 columns. I need to span only one specific field to span to 3 columns. I believe that is something to do with the field id. How do I implement it?</p>
