Web accessibility means designing websites that people with different abilities can use, including people with visual, hearing, motor or cognitive disabilities. For Joomla, this depends on templates, extensions and editorial content.
What to check
Core tasks should work with a keyboard. Visible focus shows which control is selected. Links and buttons need meaningful names, fields need labels, and form errors need accessible explanations.
Do not communicate meaning through colour alone. Contrast, text enlargement, heading structure and text alternatives matter. Video may need captions and other ways to communicate information.
Joomla accessibility
An accessible Joomla template does not guarantee that every page is accessible. Third-party menus, builders, forms or inserted content can disrupt focus order and document structure.
Test actual Joomla journeys: finding content, opening menus, signing in and submitting forms. Automated tools identify some problems but cannot replace manual checks. One successful test does not establish WCAG conformance.
Conclusion
Accessibility requires ongoing maintenance. Checking interfaces and editorial content helps make essential tasks understandable and operable.
