Live token tweaking, in zfb (zudo-front-builder)
Every visible element on this page is driven by a --zfb-* CSS custom property. Open the panel from the button above and drag any slider — the change applies before the next paint.
Cards (spacing + radius + surface)
Card A. Padding driven by
--zfb-spacing-md, corners by --zfb-radius, background by --zfb-color-surface.Card B. Stack gap driven by
--zfb-spacing-lg; outline by --zfb-color-muted.Buttons (accent / primary)
Easing demo
Click the card below to animate it. The motion uses transition-timing-function: var(--zfb-easing-tab-open). Open the panel, switch to the Easing tab, and change the semantic "Tab Open" role — the perceived animation speed changes live.
