When users tab through your website the interactive elements should receive focus in a logical order.

What you need to know

• This success criterion requires that the user can tab through the interactive elements (for example, links, form fields, buttons, etc.) in a logical way.
• For example, it wouldn’t make sense to tab from a navigation link in the header, and immediately go to the privacy policy page link in the footer, bypassing all of the content in between.
• What we’re doing here is making sure the tab order goes in a logical sequence that flows in a logical way.

What you need to do

• Ensure the links, form fields, and any other areas of engagement that receive focus on your website are tabbed through in a logical order.
• If your content includes PDF documents, make sure the tab order reflects the logical order of the document.
