- Bild-Alt-Text: Images should have descriptive alternative text (alt text) for users with visual impairments who use screen readers.
- Tastaturzugänglichkeit: Websites should be fully navigable using a keyboard for users with motor disabilities.
- Inhaltsstruktur: Proper headings, lists, and semantic HTML are important for screen reader users.
- Formulare und Schaltflächen: Forms should be labeled properly and buttons should be accessible to all users.
