3. Key Principles for Accessible Design


When diving into accessible design, it’s essential to root one’s approach in established principles. These foundational guidelines ensure that digital content is not only accessible to people with disabilities but is also usable and effective. The Web Content Accessibility Guidelines (WCAG), developed by the W3C, provide a robust framework. Here are the core principles of accessible design based on WCAG:


  • Perceivable:

    • Text Alternatives: Provide text alternatives for any non-text content, ensuring that it can be transformed into other forms like large print, braille, speech, symbols, or simpler language.

    • Adaptive: Create content that can be presented in different ways without losing meaning. This might include restructuring content or using stylesheets.

    • Distinguishable: Make it easier for users to see and hear content. This includes ensuring good color contrast, using resizable text, and avoiding autoplay for audio.

  • Operable:

    • Keyboard Accessible: Ensure all functionality is available from a keyboard without needing specific timings for individual keystrokes.

    • Enough Time: Provide users enough time to read and use content. This may involve avoiding time-limits or offering pauses for moving content.

    • Seizures and Physical Reactions: Do not design content that is known to cause seizures or physical reactions, such as flashing visuals.

    • Navigable: Offer ways to help users navigate, find content, and determine where they are in the application or website, such as through clear headings, breadcrumbs, or focus indicators.

  • Understandable:

    • Readable: Ensure text content is readable and understandable, using clear fonts and plain language.

    • Predictable: Maintain consistent navigation and naming across different parts of the site or app. Avoid unexpected changes in content or context.

    • Input Assistance: Assist users in avoiding and correcting mistakes. This could be through clear error messages, confirmations for significant actions, or offering undo options.

  • Robust:

    • Compatibility: Maximize compatibility with current and future user tools, especially assistive technologies. This involves ensuring clean and valid code.

    • Rich Internet Applications: For dynamic content and advanced user interface controls developed with JavaScript, ARIA (Accessible Rich Internet Applications) can provide ways to make them more accessible.

  • Tools and Techniques:

While the principles set the foundation, WCAG also provides specific techniques and recommendations for implementing these principles. These might involve:

  • Semantic Markup: Using HTML elements according to their intended purpose.

  • Alternative Media: Offering subtitles for videos or descriptions for complex visuals.
