Carbon Progress bar
Documents determinate and indeterminate progress bars, percentage or ratio helper text, active/success/error states, labels close to the bar, region busy relationships, and guidance to use loading or skeleton alternatives when progress is not measurable or the load is brief.
What this source can teach
Use this source to compare a documented solution with the task and states in your own product.
- Start with the original. Open the source and find the guidance or example relevant to your task.
- Trace the connection. Use the claim notes below to see how this site applies the source to specific patterns.
- Check the setting. Compare the source's platform, people, and constraints with your own decision.
Pattern Decisions This Source Supports
| Pattern | Supported decision | Required contract | Claim note |
|---|---|---|---|
| Agent progress trace | Choose agent progress trace when an agent or automation run has started and users need live status across multiple steps or tools. | The trace belongs to one run ID, reviewed plan version, objective, actor, start time, current state, and final state. | Supports the distinction between measurable progress indicators and richer trace states. |
| Progress bar | Choose progress bar when the system can report a meaningful value toward a bounded operation. | The progress bar appears only after the operation starts and is scoped to the affected file, job, card, dialog, or page region. | Carbon supports progress bars for measurable system operations, labels, helper values, determinate and indeterminate modes, active/success/error states, region busy semantics, and alternatives. |
Comparisons supported by this source
- Agent progress trace vs agent plan preview vs streaming response vs activity log vs progress bar vs human approval gate
Supports the comparison boundary between measurable progress bars and non-percent trace milestones.
- Progress bar vs loading spinner vs loading skeleton vs step navigation
Carbon supports progress bars for downloads, uploads, data processing, percent or ratio helper text, labels near the bar, and active/success/error states.
Evidence Role
