No, if you don't have a defined height you will need to either use "display: table", the table-cell technique, or flexbox. When I told the site that I had a defined height, however, it still suggested the table-cell trick, which was not the optimal solution because of the extra markup required.

In my experience, most of the time when I do want to center something vertically, I have a defined height (which can be a percentage!), so absolute centering is the solution of choice.

With no defined height you can still use the `translate(-50%, -50%)` hack, right? I'm kinda surprised it hasn't been mentioned in this thread at all; I use it all the time. http://codepen.io/padolsey/pen/NqKzVG
