NEVER use role="application" on a widely containing element such as <body> if your page consists mostly of traditional widgets or page elements such as links that the user does not have to interact with in focus mode. Using role="application" unnecessarily can cause huge headaches for any assistive technology user trying to use your site/application. Only put it on the <body> element if your page consists solely of a widget or set of widgets that all need the focus mode1 to be turned on.


  1. Use sparingly.
  2. If your page has no resemblance to a classic document in roughly over 90% of its content.
  3. Use clear labels within your application.


  1. If a set of controls or user interface only contains these widgets that are all part of standard HTML2
  2. If your widget is dynamic such as a tree view, slider or table.

Unless you take a great deal of care in ensuring that you’ve recreated a lot of native–ish custom navigation, it’s almost always better to leave the browser/AT to its own devices. We really only recommend it on a per–in–page–widget basis, and even then: very, very carefully.


  1. Allows the user to interact with forms and ARIA–enabled HTML elements.

  2. Standard HTML refers to: text, password, search, tel and other newer input type derivates, textarea, checkbox, button, radio button (usually inside a fieldset/legend element wrapper), select & option(s), links, paragraphs, headings, and other things that are classic/native to documents on the Web.
