Timeline

Overview

Show ordered events, alerts, interventions, or model decisions. It converts domain state into an understandable, traceable and accessible interface contract.

When to use

Use HE/Timeline when you need to show ordered events, alerts, interventions, or model decisions. Keep its role distinct from transport freshness, animal-health severity and model confidence.

Example

<ol class="he-timeline"><li class="he-timeline__item"><div><b>Alert acknowledged</b><p>14:34 · Jebin</p></div></li><li class="he-timeline__item"><div><b>Movement detected</b><p>14:32 · Sensor</p></div></li></ol>

Anatomy

Anatomy stays identical in Pasture and Atlantic. A responsive layout may wrap or stack parts, but reading order and focus order remain equivalent.

Variants and states

Accessibility

Use an ordered list and include exact timestamp text in each event.

• Maintain a visible keyboard focus indicator and a logical focus sequence.
• Never rely on colour alone for operational, freshness or severity state.
• Keep touch targets at least 44 × 44 px unless the target is an inline text link.
