Rule n° 228 - Elements that are visually displayed as lists are tagged in an appropriate way in the source code.

Goal

• Enable browsers and technical aids to identify lists and then reproduce them accurately, in order to facilitate their understanding by users.
• Improve the semantics of page content and its reusability.
• Improve the accessibility of content for people with disabilities.

Implementation

Either use the appropriate HTML elements:

• ul, li for unordered listings;
• ol, lifor ordered listings;
• dl, dt, dd for listings of definitions or descriptions.

Or use the ARIA attributes to give the semantics of an unordered or ordered listing with more generically tagged content:

• give the listing container a role="list" attribute;
• give each element of the list a role="listitem" attribute;
• (there is no equivalent to definition listings via an ARIA role).

Control

For each page containing a listing:

• Check the source code of content presented in listing form (characterised by the presence of line breaks and list markers such as bullets or numbers) using a code inspector.
• Check whether the source code of these visible listings includes the HTML elements corresponding to the type of listing in question: ul, li for an unordered listing (bulleted listing), ol, li for an ordered listing (numbered listing) and dl, dt, dd for a listing of definitions or, failing that, the ARIA roles list and listitem.
