Is there a way to use flex classes in the example below to ensure columns 3 and 4 have the same height as columns 1 and 2 without using Javascript?
Specifically, how can I adjust the height of all columns automatically to match the tallest column's content?

<div class="col-md-6">1 Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.
It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with
desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
