- Avoid making assumptions about the the physical, mental, and sensory abilities of your users whenever possible.
- Your users’ technologies are capable of sending and receiving text.
That’s about all you’ll ever be able to assume.
- Users’ time and technology belong to them, not to us. You should
never take control of either without a really good reason.
- Provide good text alternatives for any non-text content.
- Use widely available technologies to reach your audience.
- Use clear language to communicate your message.
- Make your sites usable, searchable, and navigable.
- Design your content for semantic meaning and maintain separation between content and presentation.
- Progressively enhance your basic content by adding extra features. Allow it to degrade gracefully for users who can’t or don’t wish to use them.
- As you encounter new web technologies, apply these same principles when making them accessible.
