CI/CD Deploy Pipeline Timeline — Status Steps with Live Spinner

A deployment pipeline strip in the dashboard idiom: Build → Test → Deploy steps joined by connector lines that fill with state, a conic-gradient spinner on the running step, and success/pending/failed expressed with icons AND text — never color alone — so the pipeline reads correctly for color-blind engineers and screen readers alike.

## JavaScript
```js
/* No JavaScript — state is a data-state attribute per step; the spinner is a conic-gradient ring masked with radial-gradient and rotated with transform. */
```

How this works

The pipeline is an <ol> laid out with flexbox; each <li> owns the connector segment BEFORE it (a ::before flex line), so adding or removing steps never orphans a line. State rides a data-state attribute (done | running | queued | failed) and every visual — connector fill, marker style, label color — is an attribute selector: the markup an API would actually render.

The running spinner is a conic-gradient ring: a pseudo-element with background: conic-gradient(var(--tl-accent) 0 25%, transparent 25%), masked to a ring with a radial mask, spun by a keyframe rotating transform. GPU-only, no SVG, no GIF. The done state draws its check with two CSS borders rotated 45° — the classic pure-CSS checkmark.

Each state is ALSO written in visually-hidden text ('completed', 'in progress', 'failed') inside the step, because a green circle is silence to a screen reader. The aria-current="step" attribute marks the active stage — the correct ARIA for wizards and pipelines.

Techniques used: data-state attribute API driving all visuals via attribute selectors · conic-gradient ring spinner masked with radial-gradient · border-drawn CSS checkmark · aria-current="step" + visually-hidden state text · per-step ::before connectors that survive step insertion · container query flips the strip vertical below 480px container width

Make it yours

  • Drive it from your backend: render data-state per step — every visual updates from that one attribute, no class soup.
  • Add stages: duplicate an <li>; connectors are per-step so nothing else changes.
  • Spinner speed: the 0.9s rotation; sweep size is the 25% stop in the conic-gradient.
  • Failure treatment: the demo uses a ✕ + red fill; swap for an amber 'warning' by adding a data-state="warn" ruleset.

Gotchas — read before shipping

  • Never encode state in color alone — the icon shape (check/spinner/✕) and hidden text are the message; color is reinforcement (WCAG 1.4.1).
  • Put aria-current="step" on the running <li>, not aria-selected — this is not a tab list.
  • The spinner must rotate transform, not background-position — conic gradients repaint expensively; rotating the element composites.
  • Connectors drawn as ::before on each step means the FIRST step must hide its connector (:first-child::before{display:none}) — forget it and the strip grows a dangling tail.

Floor set by @container as this demo is written. The core technique itself goes back further — Chrome all.

conic-gradient and mask-composite ring tricks are baseline since 2023; the container query flip needs Chrome 105+/Safari 16+/Firefox 110+ and degrades to the horizontal layout.
