Understandable
Summary
Principle 3, Understandable, of the Web Content Accessibility Guidelines (WCAG) underscores the importance of making web content understandable for all users. This principle ensures that information and the operation of the user interface are understandable, addressing the need for clear and comprehensible content.
Why It's Important:
Understanding is key to accessibility. This principle caters to users with cognitive, language, and learning disabilities, ensuring they can comprehend and interact with web content. It involves clear language, predictable behavior, and helpful input guidance.
Examples and Scenarios:
- Clear Language Use: Using plain language and defining any technical terms or jargon.
- Consistent Navigation: Keeping navigation elements consistent across a website.
- Error Identification and Correction: Providing explicit error messages and correction suggestions in forms.
How to Comply:
Use understandable language, maintain consistent interfaces, and provide helpful input assistance. This includes clear instructions, error messages, and assistance in forms and inputs.
Exceptions:
- Complex Material: Highly technical or specialized content might inherently use complex language, but efforts should be made to simplify it as much as possible.
- Brand Names or Specific Terms: Certain terms or names might not be changed due to branding or specific usage contexts.
