Opencompositions/components/gesture-tap.html and copy what is inside into your own composition.
A component has no size or duration of its own. It takes both from the composition
you paste it into.
Variables
Every one of these has a default, so the piece works untouched. Set the ones you want to change on the element:| Variable | Default | Accepts | What it does |
|---|---|---|---|
tap_label | Follow | string | Button label shown before the tap response. |
response_label | Following | string | Button label shown when the tap releases. |
accent | green | green, blue, violet | Color used for the completed button state and response pulse. |
data-variable-values on the element that mounts it. These are the
defaults, so this behaves exactly like the preview above until you change one:
<div
data-composition-id="gesture-tap"
data-composition-src="compositions/components/gesture-tap.html"
data-variable-values='{"tap_label":"Follow","response_label":"Following","accent":"green"}'
></div>

<!--
gesture-tap: HyperFrames video primitive (ui-props / interaction / demonstrate)
Concept: a contact circle appears directly over a real pill button, presses
it, releases it into a new state, then lifts away. One mechanic, one job:
showing a decisive mobile tap response.
Variables:
- tap_label (string, default "Follow"): button label before release.
- response_label (string, default "Following"): button label after release.
- accent (enum, green | blue | violet, default green): response color.
Envelope: fixed IN and OUT with elastic HOLD only.
IN_BASE = 1.35s. The stage fades in, contact fades up at the target,
presses, then releases. The label swap, accent response, and pulse share
one release timestamp.
HOLD = max(0, D - IN - OUT). Only this phase stretches for longer mounts.
A barely visible card drift keeps the held state alive.
OUT_BASE = 0.55s. The completed mobile state fades cleanly.
If D is shorter than IN_BASE + OUT_BASE, IN and OUT compress together.
Mount contract: the runtime clones only this template. #root fills the host
box, establishes the container query basis, carries no data-width or
data-height, and registers one paused timeline under the literal
gesture-tap key.
