## JavaScript
```js
/* No JavaScript — the sun/cloud are CSS shapes on gentle loops; the hourly strip is a scroll-snap flex row; the glass carries a dark scrim for contrast over the photo. */

/* No JavaScript — rain is two repeating gradients scrolling their background-position; lightning is an opacity keyframe with a long quiet span so it feels random. */
```

How this works

The rain is one element: a pair of repeating linear gradients (thin bright streaks) animated downwards with background-position, layered at two sizes for parallax depth:

.rain{background:
  repeating-linear-gradient(12deg,transparent 0 11px,rgba(190,220,255,.5) 11px 13px) ,
  repeating-linear-gradient(12deg,transparent 0 23px,rgba(190,220,255,.28) 23px 25px);
  background-size:60px 90px,90px 140px;
  animation:fall .7s linear infinite}
@keyframes fall{to{background-position:0 90px,0 140px}}

The sun is a radial-gradient disc whose rays are a masked conic; the cloud is three overlapping border-radius blobs drifting on a 9s loop. The hourly strip is an overflow-x scroller with scroll-snap-type: x mandatory so it feels native on touch.

Make it yours

  • Rain density = the pixel gaps in the repeating gradients; angle 12deg → 0deg for straight rain, negative for wind.
  • Swap the sky photo per condition (the gradient underlay keeps failed loads pretty).
  • Hourly strip: add cells freely — snap points come from the children.
  • Lightning frequency is the keyframe's quiet span (92% of an 7s loop).

Gotchas — read before shipping

  • Animating background-position on huge areas can cost paint — cap the rain layer to the card, not the viewport.
  • Give the temperature REAL text hierarchy (clamp() the 96px number) or it overflows small playgrounds.
  • Photographs behind glass need a dark scrim for AA contrast — the card adds rgba(10,14,26,.35) before text goes on.
