Bootstrap Grid Column Clearing

I'm having a hard time understanding the column clearfix structure in bootstrap. I'm trying to create a card layout, which needs the rows in the layout to all be the same height,

Solution 1:

I don't know if this answer can help you.

Your div content is already changing as you said, so a way will be to ask javascript when document is ready.

Just have to check the max height of each targeted div, and apply it at each div.

Here is a kind of code in action : http://bootply.com/103561

Just that, I'm sorry because when I wrote the code, I was in clouds, and the var mini is not significative, it should be named 'maxi'...

And this same code in visu :

$(document).ready(  makeDivSimilar  );

functionmakeDivSimilar()
{
  var mini = 0;
  $('.col-md-4').each(function(){
      if(parseInt($(this).css('height')) > mini )
      {
        mini = parseInt($(this).css('height'));
      }  
  });
  $('.col-md-4').css('height',mini);  
}
