  Finally I found a way to make borders around my floated divs collapse like on table cells. The key was to use box-shadow instead of border. So this is actually a trick to <i>simulate</i> borders.
</p>

<p>
  I couldn't use <code>display:table-cell</code> because table cells don't get rearranged vertically the way I want in responsive scenarios.

<p>The first container:</p>

<div id="container1" class="container">
  <div>Hello, this is the first floated div</div>

</div>

<p>The second container:</p>

<div id="container2" class="container">
  <div>Hello, this is the first floated div</div>
  <div>And this is the second</div>
  <div>And finally the third one</div>
</div>
