Why a visual generator beats hand-writing CSS
For most CSS — color, spacing, typography — writing it by hand is faster than any UI. But for a handful
of properties, a visual generator is genuinely faster: properties with 3+ axes of
variation (box-shadow has 5), properties with unintuitive math (flex-basis +
flex-grow + flex-shrink), and properties whose output you need to see before
committing (favicons, gradients).
The tools in this pillar are designed for that specific case — where trial and error beats writing code blind.
