title: Bootstrap 3 merge rows and columns
body: <p>I can't figure out what is the problem with my code. I'm very new in bootstrap my problem is kinda trivial. One of my field is out of position. I have tried a different route by making only one row and instead of increasing the div sizes I reduced them, but it had the exact same problem. (Run the code in full screen mode).</p>
  
  <p>Please if you can help me out!</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
