Step indicator
Showing state and identity · researchedShows where a person is in a multi-step flow and how many steps remain.
molecule · Carbon: Progress indicator · also called Steps, Stepper
"Progress indicator" in Material and elsewhere means a bar or spinner; "Step indicator" avoids that clash.
Each block is the real component from that system’s own package, in an isolated frame. They are live: hover, focus and press them. Frames are drawn on white so systems compare on one ground, and a font a system licenses only for its own site (GOV.UK’s Transport) falls back to what the system itself specifies.

GOV.UK
Checked: component index (https://design-system.service.gov.uk/components/ , 37 components), patterns index, styles index, repo tree src/govuk/components and objects, and installed govuk-frontend 6.5.1 components directory. No step indicator. Step by step navigation pattern is a prototype-only sidebar; Task list component lists tasks with status tags.
Material Web
Checked docs/components (20 component pages), the repo top-level dirs, labs/, labs/gb/components and the installed 2.5.0 package. No stepper/steps element anywhere.
Primer
No stepper/step-indicator. Timeline (vertical event list) and ProgressBar exist but neither shows multi-step flow position. Checked: primer.style/product/components/ index, internal-components list, ui-patterns, packages/react/src tree (incl. deprecated/, experimental/, internal/).

Anatomy
- ordered list — Spec ol: list of intentionally ordered items.
- step (list item) — Spec: the li element children of ol are the items.
The seven states
| default | Non-current steps; MDN aria-current: one element in the group is styled to show the current step, and that element gets aria-current=step. |
|---|---|
| hover | n/a — Not interactive by default. |
| focus | n/a — Not focusable unless steps are links. |
| active | n/a — Not interactive. |
| disabled | n/a — Not defined by APG or HTML. |
| error | n/a — Not defined by APG or HTML. |
| loading | n/a — Not defined by APG or HTML. |
