Alert dialog

For the moment just before something hard to undo — it blocks the middle of the screen and asks once.

How to use it

  • Write the title as a question and the buttons as its answers: 'Delete account' / 'Keep it', not OK / Cancel
  • Say how much disappears, with numbers: '118 orders', not 'all your data'
  • If it would appear several times a day, demote it to a toast
  • When two buttons do not fit one row, stack them and put the recommended one at the bottom

Watch out for

  • Without role="alertdialog" and aria-modal, screen readers keep reading the page behind
  • Closing on a backdrop tap cancels by accident — let only the buttons close it
  • One red button per dialog, and give initial focus to the safe choice
