Absolute centering only works when the element you are trying to center has a defined height. If you are trying to center an element with unknown height inside a container with unknown height, the table-cell is likely the front-runner, sadly.

I like the translateY(-50%) trick. But yeah, it is a pain point. Hence flexbox.

People always suggest margin auto but at least for me having defined heights for elements is the very rare exception.
