CSS Sweet Alert Style Animated Icons

Library-free SweetAlert energy: a success dialog whose circle sweeps shut and checkmark draws on via stroke-dashoffset (with a celebratory ring burst), and an icon lab holding all three states — draw-on check, double-stroke cross with a head-shake, pulsing warning — each replayable and each annotated with the exact dash math that drives it.

## JavaScript
```js
(function(){
  var dialog=document.getElementById('ntf-24a-dialog'); if(!dialog) return;
  document.getElementById('ntf-24a-replay').addEventListener('click',function(){
    dialog.classList.remove('is-play');
    requestAnimationFrame(function(){ requestAnimationFrame(function(){ dialog.classList.add('is-play'); }); });
  });
})();

(function(){
  var lab=document.getElementById('ntf-24b-lab'); if(!lab) return;
  lab.querySelectorAll('[data-replay]').forEach(function(cell){
    cell.addEventListener('click',function(){
      cell.classList.remove('is-play');
      requestAnimationFrame(function(){ requestAnimationFrame(function(){ cell.classList.add('is-play'); }); });
    });
  });
})();
```

How this works

Every draw-on icon is the same trick: a stroke's dash pattern can be as long as the path itself, and offsetting it by that length hides the stroke entirely. Animate the offset to zero and the path 'draws':

.check{
  stroke-dasharray:34;    /* the path's length */
  stroke-dashoffset:34;   /* start fully hidden */
  animation:draw .45s cubic-bezier(.65,0,.45,1) .55s forwards;
}
@keyframes draw{ to{ stroke-dashoffset:0 } }

Get the magic number from the browser — pathEl.getTotalLength() — or eyeball it upward (too-long dasharrays still work). Choreography makes it feel expensive: circle first (.5s), check second (.45s starting at .55s), ring burst last — each element's animation-delay is the previous one's near-end. The cross variant draws TWO strokes with a 120ms stagger then head-shakes the whole icon; the warning pulses its ring with the dead-time loop from the bell topic. All three run from one .play class toggle, the JS is ten lines of replay plumbing.

Make it yours

  • Draw direction follows path direction — author the check left-to-right in the SVG and the animation reads as a tick, not a wipe.
  • Slower isn't fancier: 400–600ms per stroke; a full second of drawing reads as loading, not celebration.
  • Recolor per brand by swapping the three --c custom properties; dash math never changes.
  • Fire the dialog's primary button focus AFTER the draw completes (animationend) so keyboard users don't outrun the moment.

Gotchas — read before shipping

  • A dasharray shorter than the path leaves a visible dash pattern instead of a clean draw — when in doubt, round UP.
  • vector-effect:non-scaling-stroke keeps stroke width honest if you resize the icon — otherwise scaling the SVG scales the stroke too.
  • Draw-on icons are decoration to assistive tech — the dialog's HEADING carries the outcome; keep the SVG aria-hidden.
  • Replaying needs the class-removal + double-rAF pattern (or animation-name reset) — setting the same class twice does nothing.

Browser support

Floor set by oklch(), color-mix(), text-wrap as this demo is written. The core technique itself goes back further — Chrome any.

Dash-offset animation on SVG strokes has worked everywhere for a decade. The standalone scale/rotate used in the flourishes is Chrome 104 / Safari 14.1 / Firefox 72; swap to transform: equivalents if you must support older.
