I would like to present 4 div with size "col-md-6". If all of them got the same height, all is working (the result is like there)
1 2
3 4
But if one of them (example with 1 div) is taller than others, then result change, and the 3 is not starting at the bottom of the number 3 div
I got this :
12
2
4
4
3
I want this :
12
32
4
Thank you
