If you want a table layout, why not just use a table? Or you can use display: inline-block if you want to give a width to an inline element.

I run into plenty of situations where I have multiple lines, and I'd like the respective elements to align. It's not limited to tabular data, but it's the easiest example

Tables FTW. It's the HTML element for controlling horizontal and vertical relationships at the same time.
