Attention messages

Create a flashing message

  1. Write a very short message.
  2. Pick a high-contrast color combination.
  3. Choose a speed and use fullscreen only where flashing is appropriate.

Use flashing carefully

  • Avoid long sessions and do not point flashing content at anyone who may be photosensitive.
  • Reduced-motion settings automatically keep the message static.

Flashing text questions

Does reduced-motion stop the flash?

Yes. When the device requests reduced motion, the text remains visible without flashing.

What messages work best?

One or two urgent words are easier to notice and understand than a long sentence.
