Set flexbox children to have different heights to use up available space

问题

Using a two-column flexbox layout, how can different-sized children be made to fill all available space, instead of all children having the height of the tallest child of the row?

I set up a demo on jsbin that illustrates the problem. I'd like for all the children to be the size of their wrapped contents.

#container {

 width: 800px;
  display: flex;
  flex-wrap: wrap;
}

.cell {
  width: 300px;
  flex; 1 auto;
}


<div id="container">

<div class="cell">
Cells with arbitrarily long content.</div>

<div class="cell">
</div>

<div class="cell">
</div>

<div class="cell">
</div>

<div class="cell">
</div>

</div>

</body>
</html>

This is how Flexbox rows are expected to behave. Flexbox is not meant to recreate Masonry with pure CSS: items in one row cannot occupy space allocated for a preceding/following row (same goes for columns if you're using column orientation). You can use align-items to prevent them from stretching, but that's about it:

#container {

 width: 800px;
  display: flex;
  flex-wrap: wrap;
  align-items: flex-start;
}

.cell {
  width: 300px;
  flex: 1 auto;
  padding: 10px;
  border: 1px solid red;
}

Otherwise, you should be using the column orientation or the multi-column module (see this SO answer: https://stackoverflow.com/a/20862961/1652962)
