Checkpoint 1.10 - Core

Further uses of the abbreviation or acronym have been marked up using the <abbr> element

WCAG 1.0 Priority 3

WCAG Guideline 4. Clarify natural language usage.

Assistive technologies will attempt to pronounce or output abbreviations and acronyms as English words which may be indecipherable to visually impaired users. Correct mark-up of abbreviations or acronyms makes reading easier for users of screen readers, audio browsers and Braille devices.

Requirement

Use the <abbr> element without the title attribute to markup the acronym or abbreviation on all but the first appearance on the web page.

Note: Internet Explorer 6 and below do not recognize the <abbr> element, however this element is recommended because the <acronym> element is deprecated in the XHTML Specification.

Checking Tool
