How it works

Stylepack opens the site in a real browser, measures what renders (not what the stylesheet says) at four widths and in both themes, and stores the result as a design pack. A site already measured answers at once; a new one takes under a minute. Every value on this page comes from that pack.

Questions

What is a design token?

A named design value (a color, a font size, a spacing step) used across a product. As CSS variables, tokens let you restyle a whole site by changing one declaration.

Where do the names come from?

From the role each value plays on the measured page: --color-primary is the accent, --text-headline-lg a heading style, --space-4 a spacing step. The pack's tokens.json carries the same names in the W3C format.

Is this the whole design system?

It is the values. The design pack adds the behavior (hover, focus, menus, motion, responsive layout, dark mode), the component recipes and screenshots, in the form AI coding agents build from.
