2.4.3 - Focus order

The intent of this success criterion is to ensure that when users navigate sequentially through content, they encounter information in an order that is consistent with the meaning of the content and can be operated from the keyboard. This reduces confusion by letting users form a consistent mental model of the content.

If a web page can be navigated sequentially and the navigation sequences affect meaning or operation, focusable components receive focus in an order that preserves meaning and operability:

• close relative to reading order
• affects the interactive elements
  • ensure that the navigation order of links, form elements, etc. is logical and intuitive
