Lava trail cursor

A focusable pointer demonstration surface with a luminous molten core and a decaying lava trail. Pointer movement emits cooling droplets, arrow keys provide an equivalent keyboard demonstration, and the effect never changes the global document cursor.

Implementation field notes

Use lava trail cursor 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

  • Immersive campaigns
  • Game landing pages
  • Creative portfolios

This pointer effects pattern works best when its purpose is clear in the surrounding page hierarchy.

Accessibility contract

  • The demonstration field is focusable and supports arrow-key movement.
  • Instructions remain visible and the molten trail is decorative.
  • Reduced-motion mode keeps one stationary core and suppresses trail emission.

Integration plan

  1. Copy the standalone HTML and scoped CSS into an isolated page.
  2. Adapt hot lava, molten lava, cooling lava, rock surface 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.
