Form Accessibility

The practice of designing and implementing digital forms so they can be effectively completed by people using assistive technologies, particularly screen readers. Key requirements include: every form field must have a programmatically associated label that clearly describes the expected input; groups of related fields (like radio buttons) must use fieldset and legend elements; error messages must be clearly associated with the fields they refer to; required fields must be indicated in a way accessible to screen readers; dropdown menus and custom controls must be keyboard-operable; and the tab order must follow a logical sequence. Common accessibility failures include unlabeled fields, labels that do not match the question being asked, generic button labels ("button" instead of "Select state"), and form validation that only uses visual cues like color changes.
