Implementation field notes

Use plasma donut meter 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

  • Storage dashboards
  • Quota cards
  • Capacity monitoring

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

Accessibility contract

  • The graphic exposes a bounded meter value and accessible label.
  • Percentage and remaining capacity are visible text.
  • The plasma flare is decorative and removed in reduced-motion mode.

Integration plan

  1. Copy the standalone HTML and scoped CSS into an isolated page.
  2. Adapt plasma pink, electric blue, track color, surface color through the Inspector.
  3. Keep the semantic markup intact while replacing the sample content.
  4. Review the result at 375, 768, 1024, and 1440 pixels before shipping.
