title: Customing uikit.modal
body: <p>I'm developping an application and i want to open a large modal.</p>
  
  <pre><code>UIkit.modal.confirm('html content', function(){ myFunction() });
  </code></pre>
  
  <p>In this way it generates a default modal.</p>
  
  <pre><code>&lt;div class="uk-modal-dialog" style="min-height:0;"&gt;&lt;div&gt;
  </code></pre>
  
  <p>But i want that generates to me a modal with 80% width or a large modal. like this for exemple : </p>
  
  <pre><code>&lt;div class="uk-modal-dialog" style="min-height:0; width:80%"&gt;&lt;div&gt;
  </code></pre>
