title: Fill td with empty div contenteditable
body: <p>I have many empty (without content) contenteditable div`s in td. I need div's width:100% and height:100% of td.</p>
  
  <p>HTML:</p>
  
  <pre><code>&lt;td&gt;
      &lt;div contenteditable="true"&gt;&lt;/div&gt;
  &lt;/td&gt;
  </code></pre>
  
  <p>CSS:</p>
  
  <pre><code>td {min-width: 100px; min-height: 120px; width: 100%; height: 100%}
  td div{height: 100%; width: 100%; display:inline-block;}
  </code></pre>
  
  <p>This works if div has content in it, but if it's empty I can't see it and can't change its content (div has <code>width:0; height:0</code>).</p>
