| Definition |
Verify that the use of the aria-flowto attribute supports the intended reading order of content on the page. |
| Purpose |
- The reading order of content on the page can, in some cases, be made easier to understand by users of assistive technology with the use of
aria-flowto.
- By default the reading order used by assisitive technologies is the same as the DOM ordering of content.
- When the DOM order of content is interspersed with unrelated content,
aria-flowto can be used to keep related content together. For example a multi-column newspaper where an article spans several columns, aria-flowto can be used to make it look like one continuous column to assistive technology.
- The
aria-flowto reorganizes the content by changing the order of how the content is represented in accessibility Application Programming Interfaces (APIs) used by operating systems to communicate to screen readers.

| Techniques |
- The
aria-flowto attribute value contains a sequence of idrefs that changes the reading order of content on the page as rendered by assistive technologies.
- Since
aria-flowto changes reading order to assistive technologies, it is important to read the page with a screen reader to verify the content affected by the aria-flowto places related information in the proper sequence.
