The post doesn't say "There were three units". That's a quote you made up. The post says "the original CSS specification included 3 relative units". That is factually true. The original CSS spec lists only em, ex, and px as supported relative units, which are distinct from the five absolute units you accused them of leaving out.[0] Accusing someone of lying while lying about what they said is a bad look.

The author also has a footnote mentioning that there are actually 36 relative length units in CSS now, so it's actually a 12-fold increase in relative unit types.

Lastly, I don't think the author is even complaining about the number of units. He obviously has reservations about it, but the main point is to illustrate the growing complexity of CSS over time.

> These raw numbers tell an underlying story; websites now appear in a number of different shapes, sizes and dimensions, and CSS needs to account for that.
