If I remember well I think there are elements that will scale height as well, like <img> but I’m no expert. I try to set both of them. If you want something proportional, you can use like vh units on both properties. I don’t know if that’s what you’re asking.
— And use flex box, it’s easy to get nice results.
— Was actually asking of the meaning of wide in css. does it refer to width only or width and height :)
