Progress Predictive Progress

Shows completed work, current work, uncertainty, and what happens next for known, unknown, and multi-stage work; it is designed to show real progress, uncertainty, cancellation, and what happens next. Progress updates never announce every tiny change and allows cancellation where safe. The progress and loading variant is specialized for estimated progress must not masquerade as measured completion. Users can show real progress, uncertainty, cancellation, and what happens next while understanding the current state, available choices, and resulting consequence.

Implementation field notes

Use progress predictive progress confidently.

The preview and source are only the starting point. Use these notes to decide where the component fits, preserve its accessibility contract, and verify the adapted result.

Good fit for

  • Dataset migration
  • 2.4 million records are moving safely
  • Progress indicators

This progress indicators pattern works best when its purpose is clear in the surrounding page hierarchy.

Accessibility contract

  • The primary purpose and current state remain available as text and do not depend on color, motion, pointer position, or visual geometry.
  • Every interaction has keyboard equivalence, visible focus, predictable Escape behavior where applicable, and appropriately scoped status announcements.
  • Reduced-motion, 200% zoom, long-content, narrow-container, and forced-color behavior are part of the implementation acceptance criteria.

Integration plan

  1. Copy the standalone HTML and scoped CSS into an isolated page.
  2. Adapt trust signal, recovery highlight, feedback surface, primary text through the Inspector.
  3. Connect the defensive JavaScript, then test every control with a keyboard.
  4. Review the result at 375, 768, 1024, and 1440 pixels before shipping.
