title: CSS Overflow: overlay. Is it deprecated? How can I replace it?
body: <p>I have a legacy web app with non-standard css property value;</p>
  
  <pre><code>myClass{
      overflow: overlay;
  }
  </code></pre>
  
  <p>I googled a bit, but did not found much about this property.<br>
  <a href="http://quirksmode.org/css/css2/overflow.html" rel="noreferrer">This link</a> says that it works like <code>overflow:auto</code> for webkit browsers, but it is false.<br>
  <a href="https://jsfiddle.net/11w3LLq1/" rel="noreferrer">Simple sample to show the difference and existance of this value.</a> Checked in last chrome.</p>
  
  <p>Is it deprecated now?<br>
  Is it a crutch for legacy browsers? (What browsers exactly?)<br>
  What is the semantic of this value?<br>
  Should I replace it?<br>
  How can I replace it?   </p>
