Section 3: Understandable
The "Understandable" principle ensures that content and user interfaces are presented in a way that users can understand. This involves making content readable, predictable, and providing input assistance to minimize errors and frustration.
3.1 Readable Content
Ensure the text is readable and understandable for all users by providing definitions, clarifying unusual words, and simplifying complex language.
- Example: Use clear and simple language for general instructions.
- Example: Include explanations for jargon or abbreviations (e.g., "WCAG" stands for "Web Content Accessibility Guidelines").
3.2 Predictable Behavior
Ensure web pages operate in predictable ways, helping users understand and anticipate actions on the website.
- Example: Navigation menus should remain consistent across all pages of the website.
- Example: Prevent automatic changes in context when users focus on interactive elements.
3.3 Input Assistance
Help users avoid and correct errors when providing input by offering clear labels, feedback, and guidance.
- Example: Display real-time error messages when users submit incorrect data.
- Example: Include confirmation steps for sensitive transactions (e.g., financial or legal forms).
