title: Why isn't there a flexbox polyfill for older browsers like IE9?
body: <p>Are there some problems that prevent people from creating it? Is it too complicated?</p>
  
  <p>Maybe there is just no need for that?</p>
  
  <p>Was it created it already and I just can't find it?</p>
  
  <p>I imagine it to be a js based library and work this way:</p>
  
  <ol>
  <li><p>It checks if the browser supports flexbox natively;</p></li>
  <li><p>If it doesn't, it parses CSS and checks if an element has flexbox related rules;</p></li>
  <li><p>If it does, it tries to emulate these rules via javascript by calculating all positions and sizes of the children elements and position them using <code>position: absolute;</code>. </p></li>
  </ol>
  
  <p>Basically, the same thing that Masonry and similar libraries do, but with flexbox rules. Would that be possible to do?</p>
  
  <p>Edit: <a href="https://stackoverflow.com/questions/13934654">this question</a> doesn't explain why it can't be done.</p>
