apple-design

Apple’s fluid interface principles translated into web springs and gestures.

What it is

Knowledge distilled from Apple WWDC design talks, chiefly Designing Fluid Interfaces, mapped to CSS, Pointer Events and spring libraries. Covers response, interruptibility, momentum, materials, typography and accessibility.

Apple's approach to interface design and fluid, physical motion, translated for the web. Use when building or reviewing gesture-driven UI, spring animations, drag/swipe/sheet interactions, momentum and interruptible tran
From the upstream SKILL.md

Why it matters for design

  • Feedback fires on pointer-down, so pressed elements stop feeling dead.
  • Animations start from the live on-screen value, removing visible jumps on interrupt.
  • Flicks project a landing point, so throws land where the gesture aimed.

What it covers

  • Response
  • Direct manipulation
  • Interruptibility
  • Momentum projection
  • Materials and depth
  • Reduced motion and accessibility

How to install

apple-design

  1. Clone the repo.

    git clone https://github.com/emilkowalski/skills
  2. Point Codex at the skill file.

    skills/apple-design/SKILL.md
  3. Then describe the UI you want. Codex follows the skill.

How to run it with Codex

  1. Ask Codex to build a sheet, drawer or drag interaction.

  2. It tracks 1:1 with pointer capture and records velocity history.

  3. On release it hands velocity to a spring using the shipped damping values.

Every plugin here is free, open source, and links to its real upstream source.
