Accessible Motion: Building Animation That Respects Every Visitor

Motion needs a useful purpose

Animation can show sequence, hierarchy or cause and effect. It becomes a barrier when it flashes, moves continuously, hides information or makes reading dependent on timing. Keep the content available even if animation is disabled.

Respect the operating system's reduced-motion preference and provide a calm alternative for scroll-linked scenes.

Keep animated text accessible

When a heading is split into individual character elements, expose one coherent accessible phrase to assistive technology and hide the decorative glyph fragments from the accessibility tree. Ensure the text remains selectable or otherwise available where appropriate.

• Do not use animation as the only way to reveal essential content.
• Keep focus indicators visible during transitions.
• Avoid large parallax movement and flashing effects.
• Test keyboard navigation and screen readers.

Test the experience, not only the code

Check reduced-motion mode, zoom, touch input, keyboard use and slow devices. Ask whether a visitor can understand and complete the task if every decorative transition is removed. That is the baseline for resilient motion design.
