Aria-hidden

aria-hidden is an ARIA property that tells assistive technology to ignore specific elements. It's the opposite of making content accessible – it's intentionally hiding decorative, redundant, or potentially confusing content from screen reader users.

This might seem counterintuitive for accessibility, but aria-hidden serves an important purpose: it helps screen reader users focus on meaningful content by filtering out visual decorations, redundant information, or complex visual layouts that don't add value when read aloud.

The key is understanding when content should be hidden versus when it should be made accessible. Decorative images, visual separators, and redundant text are good candidates for aria-hidden. Important information, interactive elements, and meaningful content should never be hidden.

Decorative Images: ```html ```

Visual Separators: ```html

Redundant Text (when visual and accessible names are the same): ```html × ```

Complex Visual Layouts: ```html

Icon-Only Buttons (when aria-label provides the name): ```html ♥ ```

Never Hide Important Information: If content is meaningful or interactive, it should be accessible, not hidden.

Never Hide Interactive Elements: Buttons, links, form fields, and other interactive elements should always be accessible.

Never Hide Error Messages: Error messages and status updates should be announced to screen reader users.

Never Hide Navigation: Navigation elements are essential for screen reader users to understand site structure.

Never Hide Form Labels: Form labels are critical for understanding what information is expected.

Never Hide Headings: Headings provide structure and navigation for screen reader users.

Never Hide Alternative Text: If you have alt text, don't hide the image – make the alt text accessible instead.

Use Sparingly: Only hide content that's truly decorative or redundant. When in doubt, don't hide it.

Test With Screen Readers: Verify that hidden content doesn't contain important information that screen reader users need.

Consider Dynamic Changes: If content becomes important later (like error messages), don't hide it initially.

Document Your Decisions: Keep track of what you're hiding and why, especially in complex applications.

Review Regularly: As content evolves, ensure that hidden elements remain appropriate to hide.

Use With Alternative Content: If you hide visual content, ensure equivalent information is available through other means.

WebAbility automatically manages aria-hidden appropriately, ensuring that decorative content doesn't clutter the screen reader experience while preserving all meaningful information for assistive technology users.
