What it is

Heydon Pickering and Andy Bell's method for algorithmic, media-query-free CSS layout. Twelve composable primitives (Stack, Box, Center, Cluster, Sidebar, Switcher, Cover, Grid, Frame, Reel, Imposter, Icon) each ship with an explanation and a generator, plus an EPUB and offline access.

Why it earns a slot

Turns responsive layout into named parts you can request by name, as in 'use a Sidebar with a 30 percent threshold', which agents follow far more reliably than a description of pixel behaviour.

Know before you commit

Vanilla-CSS-first and custom-element based, so mapping the primitives onto Tailwind takes extra work. Read the three free chapters before paying.
