Success Criterion 1.4.13 - Level AA

Content on Hover or Focus

Ensure it possible to hide content which appears automatically when touching an element. It often happens that an element is touched accidentally. If new content appears, it may affect the completion of a task. Automatic content mainly causes problems for users of assistive technologies.


  • Users of assistive technologies can get stuck in an app if it is not possible to hide automatically appearing content.

  • A menu may open after a click. Users should be able to stop or undo this action.


“Can content be hidden if it gets in the way?“

You can use the screen reader or keyboard to check this.


Add a close button to content that is automatically displayed to allow users of assistive technologies to hide it.

Add close button

On Android, you can show a dialog by using AlertDialogBottomSheetDialog or DialogFragment. You should always add a close button by using the setNegativeButton method. The focus of assistive technologies is automatically trapped inside the dialog while it's visible.

val builder = AlertDialog.Builder(this)
builder.setTitle("Confirm Appt membership?")
builder.setMessage("Your bank account will be billed.")

builder.setPositiveButton("Proceed") { dialog, which ->
  // Proceed

builder.setNegativeButton("Cancel") { dialog, which ->
  // Cancel
