Finding the Perfect Underline

From Marcin Wichary on Medium:

The perfect underline should be visible, but unobtrusive — allowing people to realize what’s clickable, but without drawing too much attention to itself. It should be positioned at just the right distance from the text, sitting comfortably behind it for when descenders want to occupy the same space…


I believe Medium’s fastidiousness regarding typography is one of the defining characteristics of their brand.
