Re: [csswg-drafts] Proposal: Add a Visual-degree (vad) Unit for Perceptual Sizing in CSS. (#14381)

for same px number like 16px for general words, its physical height is same in a laptop and in a 100 inches big screen, and causing its imposible to distinguish the words in big screen. This reality makes your idea of making a fixed ratio link between vad and px, is impossible.
