Examples demonstrating proper ARIA attributes, help text connections, and accessible validation patterns.
Use aria-describedby to connect help text to inputs.
Screen readers announce help text when the input receives focus.
Space-separate multiple IDs in aria-describedby.
Screen readers announce them in order.
When validation fails, reference both help text and error message in
aria-describedby. Add aria-invalid="true"
to indicate the invalid state.
Use both required and aria-required="true".
Add a visual indicator (asterisk) for sighted users.
Use <fieldset> and <legend> to group
related controls. Screen readers announce the legend with each control.
Add role="switch" to switch controls so screen readers
announce them as switches rather than checkboxes.
When hiding labels visually, use .visually-hidden
(not display: none) so screen readers still announce them.
Use aria-live regions to announce validation errors
to screen readers when the form is submitted.
On validation error, move focus to the first invalid field. This helps keyboard and screen reader users find errors quickly.
