title: CSS margin vh not working right
body: <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>    #grenze
      {
       background: green;
       height: 96vh;
       width: 96vh;
      }
      
      #baukasten
      {
       background: white; 
       height: 86vh; 
       width: 86vh; 
       margin: 5vh;
       border: 1px solid #DDDDDD;  
       overflow: hidden;
      }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div id="grenze"&gt;
     &lt;div id="baukasten"&gt;   
     &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>Margin works only to left but not to top, I tried with different browsers and it's always the same. What could be the problem here? Is it a bug?</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>I can't use padding on <code>grenze</code> instead because</p>
  
  <pre><code>            $( ".dragresize" ).draggable({
                  containment: "#grenze"
              });
  </code></pre>
  
  <p>Won't do what I need</p>
