Panel Reveal - transitions.dev-inspired primitive for HyperFrames.
|
||||
|
||||
Paste the markup, CSS and script into a composition. Use the timeline
|
||||
integration note at the bottom as the starting point for deterministic GSAP
|
||||
animation.
|
||||
|
||||
Variables. The script reads each one, falls back to the declared default on
|
||||
anything missing or unrecognised, and writes the result as a custom property
|
||||
the CSS below consumes. The timeline recipe at the end is untouched by them:
|
||||
it keeps driving the single open value from 0 to 1.
|
||||
|
||||
- title (string, default "Motion tokens"): the header line above the fold.
|
||||
- width (narrow | standard | wide, default standard): how wide the panel
|
||||
sits, 280, 360 or 480 px.
|
||||
- tone (paper | ink, default paper): the surface family. paper is the
|
||||
white card on a light frame, ink is the same card inverted for dark
|
||||
frames, border and body copy included.
|
||||
- reveal (fade | solid, default fade): whether the body fades in with the
|
||||
height. fade is the shipped motion, solid keeps the body at full opacity
|
||||
so only the height opens. Both look the same once the panel is open.
|
||||
|
||||
On every default the result is identical to the original: a 360px white card
|
||||
whose body fades in as it grows.
