Web accessibility (often abbreviated as a11y) ensures that digital experiences are usable by everyone, including people with disabilities. Over 1 billion people globally live with disabilities, and inaccessible design can exclude them from education, employment, healthcare, and social connections. For developers, designers, and organizations, accessibility isn’t just a legal requirement—it’s a moral imperative.
Drawing from industry standards like the Web Content Accessibility Guidelines (WCAG) and practical expertise, here’s an in-depth exploration of 11 golden rules to build inclusive digital products.
1. Use Semantic HTML
Why It Matters: Semantic HTML tags (e.g., <header>, <nav>, <button>) provide meaning to content, helping screen readers interpret page structure. Non-semantic elements like <div> or <span> lack context, creating confusion for assistive technologies.
Implementation:
Why It Matters: Many users rely on keyboards (or alternatives like sip-and-puff devices) due to motor disabilities.
Implementation:
<a href="#main" class="skip-link">Skip to main content</a>
Designer Tip: Ensure focus states (e.g., outlines) are visible and consistent with your design system.
3. Provide Meaningful Alt Text for Images
Why It Matters: Alt text describes images to screen reader users. Decorative images should have empty alt (alt="") to avoid clutter.
Implementation:
Why It Matters: Low contrast ratios make text illegible for users with low vision or color blindness.
Implementation:
Why It Matters: Accessible Rich Internet Applications (ARIA) roles enhance accessibility for dynamic content (e.g., live regions, modals).
Implementation:
<div role="alert" aria-live="assertive">Error: Invalid email format.</div>
6. Design Accessible Forms
Why It Matters: Forms are critical for tasks like logging in or purchasing, but unclear labels or errors can block users.
Implementation:
Why It Matters: Focus rings show users where they are on the page. Removing them disorients keyboard users.
Implementation:
Why It Matters: Users may zoom in or use custom font sizes. Fixed layouts can break responsiveness.
Implementation:
Why It Matters: Auto-playing videos or audio can overwhelm users with cognitive disabilities or interfere with screen readers.
Implementation:
<video controls muted>...</video>
10. Test with Screen Readers and Assistive Tools
Why It Matters: Testing uncovers issues automated tools miss.
Implementation:
Why It Matters: Accessibility evolves with technology. Teams must stay updated.
Implementation:
Building inclusive products requires collaboration across roles. Developers must write semantic code, designers must prioritize clarity, and organizations must foster a culture of empathy. By adhering to these 11 rules, you’ll not only comply with standards like WCAG but also create experiences that empower all users.
Remember: Every line of code and design choice can either exclude or include. Choose inclusion.

1. Use Semantic HTML
Why It Matters: Semantic HTML tags (e.g., <header>, <nav>, <button>) provide meaning to content, helping screen readers interpret page structure. Non-semantic elements like <div> or <span> lack context, creating confusion for assistive technologies.
Implementation:
- Use <button> for interactive actions (not <div class="button">).
- Structure content with headings (<h1> to <h6>) in logical order.
- Label form elements with <label> and associate them using for and id. Designer Tip: Collaborate with developers to ensure wireframes reflect semantic structure. Common Pitfall: Overusing <div> for interactive elements, which breaks keyboard navigation.
Why It Matters: Many users rely on keyboards (or alternatives like sip-and-puff devices) due to motor disabilities.
Implementation:
- Test all interactive elements (links, buttons, forms) using the Tab key.
- Manage focus order with tabindex (avoid tabindex > 0).
- Add “Skip to Content” links to bypass repetitive navigation. Developer Example:
<a href="#main" class="skip-link">Skip to main content</a>
Designer Tip: Ensure focus states (e.g., outlines) are visible and consistent with your design system.
3. Provide Meaningful Alt Text for Images
Why It Matters: Alt text describes images to screen reader users. Decorative images should have empty alt (alt="") to avoid clutter.
Implementation:
- Be concise but descriptive: alt="Golden retriever playing fetch" instead of alt="dog".
- Use aria-hidden="true" for purely decorative images. Designer Tip: Provide context for complex images (e.g., infographics) in surrounding text or captions.
Why It Matters: Low contrast ratios make text illegible for users with low vision or color blindness.
Implementation:
- Aim for AA compliance (4.5:1 for normal text, 3:1 for large text).
- Test contrast using tools like . Designer Tip: Avoid conveying information through color alone (e.g., “red indicates errors”). Use icons or text labels.
Why It Matters: Accessible Rich Internet Applications (ARIA) roles enhance accessibility for dynamic content (e.g., live regions, modals).
Implementation:
- Use role="navigation" for nav bars or aria-live="polite" for live updates.
- Avoid “ARIA overload”—semantic HTML should be your first choice. Developer Example:
<div role="alert" aria-live="assertive">Error: Invalid email format.</div>
6. Design Accessible Forms
Why It Matters: Forms are critical for tasks like logging in or purchasing, but unclear labels or errors can block users.
Implementation:
- Group related fields with <fieldset> and <legend>.
- Provide clear error messages (e.g., “Email is required” instead of “Invalid input”). Designer Tip: Use proximity and spacing to associate labels with inputs visually.
Why It Matters: Focus rings show users where they are on the page. Removing them disorients keyboard users.
Implementation:
- Avoid outline: none in CSS without providing custom focus styles.
- Style focus states with high contrast (e.g., button:focus { border: 2px solid #000 }).
Why It Matters: Users may zoom in or use custom font sizes. Fixed layouts can break responsiveness.
Implementation:
- Use relative units (e.g., rem, %) instead of px.
- Test designs at 200% zoom and on small screens. Designer Tip: Create fluid grids that adapt to text resizing without overlapping content.
Why It Matters: Auto-playing videos or audio can overwhelm users with cognitive disabilities or interfere with screen readers.
Implementation:
- Provide controls to pause, stop, or adjust volume.
- Use muted and controls attributes for video:
<video controls muted>...</video>
10. Test with Screen Readers and Assistive Tools
Why It Matters: Testing uncovers issues automated tools miss.
Implementation:
- Learn basic screen reader commands (e.g., NVDA, VoiceOver).
- Test keyboard navigation and form validation. Tools to Try:
- for automated audits.
- for visual feedback.
Why It Matters: Accessibility evolves with technology. Teams must stay updated.
Implementation:
- Follow experts like or .
- Include accessibility in design sprints and code reviews.
