MicroInteractionCss [pattern] v1.0.0

Five reusable pure-CSS micro-interaction recipes: button press (asymmetric timing), checkbox stroke-dashoffset check, toggle switch, input focus ring, and form shake on invalid submission.

Recipes

• Button press: scale(0.97) on :active with asymmetric transition — press 80ms ease-in, release 200ms ease-out
• Checkbox: SVG path with stroke-dashoffset 24→0 on :checked, 200ms ease-out
• Toggle switch: translate X on :checked with cubic-bezier(0.34,1.56,0.64,1) — slight overshoot for 'snap' feel
• Input focus ring: outline width 0→2px with clip-path circle expand, 150ms
• Form shake: @keyframes shake with translate(-6px) → (6px) × 3, 300ms — fires via .is-invalid class on submit

Css Tokens

• Press duration: 80ms (down) / 200ms (up)
• Focus ring: 2px solid oklch(65% 0.2 260), offset 2px
• Shake amplitude: ±6px, duration 300ms
• Toggle overshoot: cubic-bezier(0.34, 1.56, 0.64, 1)

Rationale

Micro-interactions provide physical feedback that confirms user actions. Pure CSS implementations have zero JS overhead and respect the browser's native rendering pipeline.
