Social Media Comment Section

A threaded comment skeleton on soft lavender glass: each comment pairs a gradient-tinted circular avatar with a short name line and a two-line paragraph block, cascading in with staggered shimmer. The avatar sits aligned to the name's baseline zone — the micro-detail that separates a polished skeleton from an obviously fake one.

## JavaScript
```js
/* No JavaScript — top-aligned avatars, per-user color-mix tints and staggered delays make the thread feel alive while loading. */
```

How this works

Each comment is a flex row: a 36px circle (flex-shrink:0, nudged 2px down to meet the username zone) beside a column of one short name line (~30%) and two paragraph lines (100%, then narrower). Avatars carry a barely-there oklch gradient fill via color-mix so each row hints at a different user without any images.

Shimmer is the shared .ssc-sk class — gradient overlay on a compositor-only translateX sweep — and each comment delays it by 150ms, producing the top-down cascade users associate with a feed streaming in.

Make it yours

  • Indent replies with margin-left:48px (avatar + gap) for nesting.
  • Vary the second paragraph line width per comment for organic texture.
  • Shrink avatars to 28px for compact reply threads.
  • Rotate the avatar tint hues to suggest a livelier thread.

Gotchas — read before shipping

  • Align the avatar to the name line, not the block centre — real comments top-align and the swap would jump otherwise.
  • Keep name lines clearly shorter than paragraph lines; equal widths destroy the anatomy.
  • Reserve full two-line height even for likely one-liners — whitespace beats layout shift.

oklch/color-mix tints are the modern layer; structure and shimmer run on 2019+ engines with hex fallbacks.
