title: Flexbox: Multiple containers, containers on flex items?
body: <p>Is it bad practice to use multiple flex containers, actually flex containers on flex items ?</p>
  
  <p>I have one main div which is assigned display:flex and then I have two div's and I have a <code>flex-grow: 1</code> assigned so that they fill up exactly 50% each.</p>
  
  <p>Now in each DIV I have more DIVs with content inside but I wish to align that content vertically, so could I apply a <code>display:flex</code> on this too ?</p>
  
  <p>Maybe I am being over paranoid about flexbox ?</p>
  
  <p>I discovered flexbox lately and for me it seems to fix a lot of issues of css, so I am using it a lot.</p>
