I have a parent div, I set max heigth, overflow auto for it. And it have two children div. But I saw the height of parent div equals sum of two children's height. And It only working when I add padding bottom to Parent div or Last children div. Thanks for any help.

CodePudding user response：

If the children have in sum bigger height, you should increase the size of the parent.

I recommend you to learn about flex-box, here's a good website for that flex-box
