问使用Bootstrap 3，列是否有可能包装并保持相同的高度？

EN

$(document).ready(function(){
  var biggestHeight = 0;
  var flexColumns = $('.display-flex > div');
  flexColumns.each(function(){
    if($(this).height() > biggestHeight){
      biggestHeight = $(this).height();
    }
  });
  flexColumns.height(biggestHeight);
});

.row.display-flex {
    display: flex;
    flex-wrap: wrap;
}
.row.display-flex > [class*='col-'] {
    display: flex;
    flex-direction: column;
}

div[class*='col-'] {
    background-color: #eaeaea;
    border: 1px solid;
}
