WAI-ARIA
WAI-ARIA is a W3C specification defining roles, states, properties, and other accessibility semantics for communicating web interface information to assistive technologies.
Everyday Data Visualization
A W3C standard defining roles, states, properties, and attributes that improve the accessibility of dynamic web content.
- How it is used
- Improves screen-reader access to dynamic data visualizations by naming chart elements.
- How deep it goes
- Explains two accessible-name attributes and bar-level labels, but stops short of broader ARIA internals.
- Examples
- Uses bar graphs and short labels assigned individually to their bars.
- What you can do after
- Apply it via aria-label and aria-labeledBy to give chart elements concise screen-reader names.
React in Depth
WAI-ARIA is a W3C specification defining semantics, roles, states, and properties that make web content accessible to assistive technologies.
- How it is used
- Uses semantic roles to test React components through the interface that assistive technologies can perceive.
- How deep it goes
- Defines roles and implicit-role overrides, but stops short of detailed specification coverage.
- Examples
- Demonstrates MenuItem markup and tests listitem and link roles with href, title, and text assertions.
- What you can do after
- Apply React Testing Library role queries to test components through accessible semantics.
WordPress Power Toolkit: Harness AI to build next-level websites
Accessible Rich Internet Applications (ARIA) is a web standard for adding semantic roles, states, and properties to HTML interfaces so assistive technologies can interpret them.
- How it is used
- Improves theme accessibility by labeling site structure and content for screen readers, then checking the result with browser tools.
- How deep it goes
- Identifies ARIA roles and gives inspection and Lighthouse-testing steps, but does not detail how to author role markup.
- Examples
- Names presentation, option, list box, and group roles and recommends inspecting WordPress themes such as Astra or GeneratePress.
- What you can do after
- Evaluate theme accessibility by inspecting ARIA roles and running Lighthouse’s Accessibility analysis.
