Odometer Roll

How it works

Odometer Roll is an animated entrance & kinetic text effect rendered entirely in CSS. Each character is wrapped in its own span so it can animate independently — the HTML and JSX exports include that per-letter markup.

Controls

Odometer Roll exposes 3 dedicated controls — Reel Length, Roll Time and Cell Chrome — on top of the shared type controls (font, weight, letter-spacing and case). Open it in the generator to tune every value live, then copy the updated CSS.
