Aligning the height of the block along the larger side, how to do it?

Question

css

Hi everyone, here's the gist.
There are 2 blocks, left and right . One may be taller than the other depending on the size of the content.
You need to make sure that the block that is smaller in height always grows to the height of the second block.
That is, so that both sides are always the same height.
Is it possible to do this in CSS, if not, then tell me how to implement it in jquery.
