title: Flexbox vs Twitter Bootstrap (or similar framework)
body: <p>I have recently discovered <code>Flexbox</code> when I was looking for a solution to make divs the same hight, depending on the highest one.</p>
  
  <p>I have read the <a href="http://css-tricks.com/snippets/css/a-guide-to-flexbox/">following page</a> on CSS-tricks.com and it convinced me that <code>flexbox</code> is a very powerful module to learn and use. However, it also made me think about the fact that Twitter Bootstrap (and similar frameworks) offer kind of the same functions (+ of course a lot extra) with their grid systems.</p>
  
  <p>Now, the questions are: What are the pros and cons of <code>flexbox</code>? Is there something one can't do with Flexbox that one can do with a framework like Bootstrap (of course purely talking about the grid system)? Which one is faster when implemented on a website?</p>
  
  <p>I'm guessing when only for the grid system, it's smarter to purely use <code>flexbox</code>, but what if you're already using a framework, is there something <code>flexbox</code> can add?</p>
  
  <p>Are there any reasons to choose <code>flexbox</code>'s "grid system" over a framework's?</p>
