Behind the interaction
The details
that make it work.
Notes from the actual components: how they behave, why they move, and what to preserve when making them your own.
Note 01One island, one open tool
The toolbar keeps drawing, color, effects, and typography in one connected surface. Opening a tool closes the previous one. The container expands before its panel appears, then lets the panel settle before collapsing.
Its example uses the exact toolbar from samhc.us in a separate document. Fonts, theme changes, fixed canvases, cursor effects, and drawing scroll locks belong to that document. The restart control sits outside the example so there is always a way back.

Note 02Motion should explain the change
A shared layout transition connects the trigger to the content it reveals. Keep the relationship visible, give the destination a clear close action, and avoid moving unrelated controls.
Reduced motion needs its own path. This collection uses the visitor’s motion preference to replace travel with short opacity changes or immediate updates. Check both paths when adapting a component.

Note 03A sound is feedback, too
Short cues distinguish a tap from a toggle or an expanding panel. The sound pack synthesizes them with Web Audio after a user gesture, so the browser can authorize playback.
A slider should tick when its value moves, not while a pointer is held beyond the end of its track. Keep audio optional in your own interface, and pair it with visible feedback.
