Open Source Matters
Joomla accessibility
Joomla accessibility leverages the platform's WCAG-aware Cassiopeia default template and Joomla's accessibility initiative — but the platform's smaller extension ecosystem means accessibility maintenance is more manual than WordPress or Drupal.
What does accessibility mean on Joomla?
Joomla has improved accessibility significantly since version 4. The default Cassiopeia template targets WCAG 2.1 AA. Smaller ecosystem means fewer accessibility-ready extensions.
