2.1.1 Keyboard

키보드

Summary

All functionality must be operable through a keyboard. Users with motor disabilities, screen reader users, and speech-input users all reach the page through the keyboard interface. Native elements satisfy this for free; failures almost always come from buttons built out of divs.

Common failures

  • A `<div onclick>` button that Tab never reaches and that ignores Enter and Space.
  • Binding functionality only to drag-and-drop or hover, with no keyboard alternative.
