Theme Switch

CSS custom properties on a container element swap every colour token at once — one class change, zero JS style writes.

All colour values inside the preview are CSS custom properties (--thm-ink, --thm-card, etc.) defined on the scene container. Toggling the .thm-dark class on that container flips every token simultaneously. CSS transitions on each property then animate the colour change smoothly. The switch itself never writes a colour — JS only toggles one class and updates aria-checked. Two switch variants (pill and segmented) live in the DOM at the same time; a second class on the scene hides one and reveals the other.

FIELD GUIDE

How a specimen works.

FOUR STEPS

Every specimen is presented like lab equipment — framed, labelled, and ready to be taken apart.

STEP 01

Open the stage.

Each component sits inside a framed preview viewport with registration ticks, a live frame counter, and the easing curve plotted alongside it.

STAGE

STEP 02

Slow it down.

Step through frames, swap easing, toggle reduced motion. Read the animation the way you’d read a contact sheet.

SCRUB

STEP 03

Read the source.

Every specimen is one self-contained file — HTML markup, a CSS block, and vanilla JavaScript. No framework, no build step, no dependencies.

ONE FILE

STEP 04

Take it home.

Copy the file, drop it in your project, change the props. No CLI, no install, no lock-in. MIT licensed.
