aria-flowto
The global aria-flowto
attribute identifies the next element (or elements) in an alternate reading order of content. This allows assistive technology to override the general default of reading in document source order at the user's discretion.
Description
Web pages should be sequentially navigable. For this reason, developers are dissuaded from using the global tabindex attribute which can change tab order and the CSS order
property, which can change visual order from the DOM order. However, in rare circumstances a reading path different from the source order is required. For such cases, the aria-flowto
attribute can make the content more accessible for users of assistive technologies.
The global aria-flowto
attribute lets the author indicate to assistive technology users which element or elements might want to be focused on next, providing an alternate reading order to the source order. This allows assistive technology to read a document in an order other than the default document source reading order.
When aria-flowto
has a single id reference, it allows assistive technologies to, at the user's request, go to the element targeted via that id
instead of reading the document in the order of the DOM. When the aria-flowto
value uses a space separated list of multiple id
references, assistive technology can provide the user with a list of path choices, with each id
referenced being a choice. The path choice names are determined by the accessible name of each target element of the aria-flowto
attribute.
Note: Setting aria-flow
does not impact the content's tab order. It only provides users the option to follow a content path that doesn't match the DOM order when using tech that supports this attribute.
