Understanding Accessibility-First Web Design

Web accessibility refers to the practice of designing and developing websites that can be used by everyone, including people with disabilities. For SMEs across Ireland and the UK, creating accessible websites is not just a moral imperative but also a business advantage and, increasingly, a legal requirement.

Accessibility-first design places these considerations at the beginning of the design process rather than treating them as an afterthought. This approach ensures that digital content is perceivable, operable, understandable, and robust for all users, including those with visual, auditory, motor, or cognitive impairments.

The Business Case for Accessibility

Beyond ethical considerations, there are compelling business reasons for SMEs to implement accessibility-first design:

Market Reach and Inclusion

• Approximately 22% of the UK population and 13.5% of the Irish population have some form of disability
• The combined spending power of people with disabilities (the “Purple Pound”) in the UK alone is estimated at £274 billion annually
• Accessible websites reach older demographics more effectively, particularly important in regions with ageing populations

Legal Compliance and Risk Mitigation

• The Equality Act 2010 in the UK and the Disability Act 2005 in Ireland require businesses to make reasonable accommodations for people with disabilities
• EU Web Accessibility Directive requirements increasingly influence digital regulations across member states and the UK
• Non-compliance can result in legal action, with precedent-setting cases becoming more common in both regions

SEO and User Experience Benefits

• Many practices directly improve search engine optimisation
• Accessible sites typically have better overall usability for all visitors
• Site structure improvements often lead to faster page load times

Brand Reputation and Corporate Social Responsibility

• Demonstrating commitment to inclusion enhances brand perception
• Accessibility initiatives align with broader corporate social responsibility goals
• Positive experiences from accessible design generate word-of-mouth recommendations

Key Guidelines and Standards

Understanding the relevant standards provides a framework for implementation:

Web Content Accessibility Guidelines (WCAG)

The Web Content Accessibility Guidelines are the globally recognised standard for web accessibility, organised around four principles:

Perceivable

• Information must be presentable to users in ways they can perceive
• Content cannot be invisible to all of their senses

Operable

• Interface components and navigation must be operable
• Users must be able to interact with all controls and interactive elements

Understandable

• Information and operation of the interface must be understandable
• Content should appear and operate in predictable ways

Robust

• Content must be robust enough to be interpreted reliably by a wide variety of user agents
• Content should remain accessible as technologies advance

WCAG defines three levels of conformance:

• Level A: Minimum level of accessibility
• Level AA: Addresses the most common barriers for disabled users (the standard most organisations should target)
• Level AAA: The highest level of accessibility

UK and Ireland-Specific Regulations

UK Regulations:

• The Public Sector Bodies (Websites and Mobile Applications) Accessibility Regulations 2018 requires public sector websites to meet WCAG 2.1 Level AA standards
• The Equality Act 2010 applies accessibility requirements to all service providers, including private sector websites

Irish Regulations:

• The Disability Act 2005 requires public bodies to make their services accessible
• The EU Web Accessibility Directive has been transposed into Irish law, requiring public sector bodies to comply with WCAG 2.1 Level AA

While these regulations focus primarily on public sector organisations, they establish standards that increasingly influence expectations for private sector websites as well. For SMEs, adopting these standards demonstrates due diligence and commitment to inclusion.

Practical Implementation of Accessibility-First Design

Putting accessibility-first design into practice means going beyond theory to embed inclusive thinking into every stage of the digital design and development process. From planning clear content structures to choosing accessible colour palettes and building intuitive navigation, each decision should prioritise usability for people of all abilities. This section explores practical steps and tools that help teams consistently deliver accessible digital experiences that meet both user needs and compliance standards.

Structure and Navigation

A logical, consistent structure forms the foundation of accessible websites:

Semantic HTML

Using appropriate HTML elements communicates the meaning and structure of content to all users:

<!– Poor accessibility –>

<div class=”heading”>Our Services</div>

<div class=”content”>

  <div class=”service”>Service 1</div>

  <div class=”service”>Service 2</div>

</div>

<!– Good accessibility –>

<h2>Our Services</h2>

<ul>

  <li>Service 1</li>

  <li>Service 2</li>

</ul>

Heading Hierarchy

Maintain a logical heading structure that reflects the content organisation:

<h1>Company Name</h1>

<h2>Services</h2>

  <h3>Web Design</h3>

  <h3>Digital Marketing</h3>

<h2>About Us</h2>

  <h3>Our Team</h3>

  <h3>Our History</h3>

Skip Navigation

Provide a way for keyboard users to bypass repetitive navigation:

<body>

  <a href=”#main-content” class=”skip-link”>Skip to main content</a>

  <header>

    <!– Navigation menu –>

  </header>

  <main id=”main-content”>

    <!– Main content starts here –>

  </main>

</body>

.skip-link {

  position: absolute;

  top: -40px;

  left: 0;

  background: #000;

  color: white;

  padding: 8px;

  z-index: 100;

}

.skip-link:focus {

  top: 0;

}

ARIA Landmarks

Use ARIA roles to identify page regions:

<header role=”banner”>

  <!– Site header content –>

</header>

<nav role=”navigation”>

  <!– Navigation menu –>

</nav>

<main role=”main”>

  <!– Main content –>

</main>

<aside role=”complementary”>

  <!– Sidebar content –>

</aside>

<footer role=”contentinfo”>

  <!– Footer content –>

</footer>

Content

Ensuring content is accessible to users with different abilities:

Text Alternatives for Images

Provide descriptive alt text for informative images:

<!– Informative image –>

<img src=”chart-2023-sales.png” alt=”Bar chart showing sales growth of 24% in 2023 compared to 2022″>

<!– Decorative image –>

<img src=”decorative-divider.png” alt=””>

Colour Contrast

Ensure sufficient contrast between text and background:

/* Poor contrast */

.low-contrast {

  color: #999;

  background-color: #777;

}

/* Good contrast (meets WCAG AA) */

.good-contrast {

  color: #222;

  background-color: #fff;

}

Tools like the WebAIM Contrast Checker can help verify your colour combinations meet WCAG requirements.

Responsive Text

Ensure text can be resized without loss of content:

/* Using relative units for typography */

body {

  font-size: 100%; /* Base font size */

}

h1 {

  font-size: 2em; /* Relative to base font */

}

p {

  font-size: 1rem; /* Relative to root element */

  line-height: 1.5; /* Proportional line height */

}

Text in Images

Avoid text in images where possible. When necessary, provide the same information in the alt text and consider using the <figcaption> element:

<figure>

  <img src=”infographic.jpg” alt=”Infographic showing the 5 steps of our design process: Discovery, Planning, Design, Development, and Launch”>

  <figcaption>Our 5-step design process ensures comprehensive project delivery</figcaption>

</figure>

Forms and Interactive Elements

Forms often present significant accessibility challenges:

Labelled Inputs

Explicitly associate labels with form controls:

<!– Using for/id association –>

<label for=”email”>Email Address</label>

<input type=”email” id=”email” name=”email”>

<!– Wrapping method –>

<label>

  Email Address

  <input type=”email” name=”email”>

</label>

Error Identification

Provide clear error messages that identify the problem and suggest corrections:

<div class=”form-group”>

  <label for=”phone”>Phone Number</label>

  <input type=”tel” id=”phone” name=”phone” aria-describedby=”phone-error” class=”invalid”>

  <p id=”phone-error” class=”error-message” role=”alert”>

    Please enter a valid UK phone number (e.g., 07700 900123)

  </p>

</div>

Keyboard

Ensure all interactive elements are keyboard accessible:

<!– Interactive elements need to be focusable –>

<div class=”card” tabindex=”0″ role=”button” aria-pressed=”false” onclick=”toggleSelection(this)”>

  <h3>Service Package</h3>

  <p>Description of the service package</p>

</div>

// Ensure keyboard interaction matches mouse interaction

document.querySelectorAll(‘[role=”button”]’).forEach(button => {

  button.addEventListener(‘keydown’, (e) => {

    // Activate on Enter or Space key

    if (e.key === ‘Enter’ || e.key === ‘ ‘) {

      e.preventDefault();

      button.click();

    }

  });

});

Focus Management

Ensure visible focus indicators and logical tab order:

/* Enhance focus styles beyond browser defaults */

:focus {

  outline: 3px solid #4d90fe;

  outline-offset: 2px;

}

/* For non-text elements that need more visible focus */

.btn:focus, [role=”button”]:focus {

  box-shadow: 0 0 0 3px rgba(77, 144, 254, 0.5);

  outline: none;

}

Media

Making multimedia content accessible to all users:

Video Captions and Transcripts

Provide closed captions for video content and transcripts for audio:

<video controls>

  <source src=”company-video.mp4″ type=”video/mp4″>

  <track kind=”captions” src=”captions.vtt” srclang=”en” label=”English” default>

  Your browser does not support the video tag.

</video>

<details>

  <summary>Video Transcript</summary>

  <div class=”transcript”>

    <!– Full text transcript of the video –>

  </div>

</details>

Audio Descriptions

For videos with important visual information, provide audio descriptions:

<video controls>

  <source src=”product-demo.mp4″ type=”video/mp4″>

  <track kind=”captions” src=”captions.vtt” srclang=”en” label=”English”>

  <track kind=”descriptions” src=”descriptions.vtt” srclang=”en” label=”Audio Descriptions”>

  Your browser does not support the video tag.

</video>

Mobile Considerations

Ensuring accessibility across devices:

Touch Target Size

Ensure interactive elements are large enough for users with motor impairments:

.touch-target {

  min-width: 44px;

  min-height: 44px;

  padding: 12px;

}

Pinch-to-Zoom

Never disable zooming in your viewport meta tag:

<!– Good: Allows user zooming –>

<meta name=”viewport” content=”width=device-width, initial-scale=1″>

<!– Bad: Prevents user zooming –>

<meta name=”viewport” content=”width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no”>

Orientation

Ensure content works in both portrait and landscape orientations:

/* Responsive design that works in any orientation */

@media screen and (orientation: portrait) {

  /* Portrait-specific styles */

}

@media screen and (orientation: landscape) {

  /* Landscape-specific styles */

}

Testing and Validation

Regular testing is crucial for ensuring accessible web design:

Automated Testing Tools

These tools provide a starting point for identifying issues:

• WAVE Web Accessibility Evaluation Tool: Browser extension that provides visual feedback about accessibility issues
• Axe DevTools: Developer-focused toolset for accessibility testing
• Lighthouse: Built into Chrome DevTools with an accessibility audit section
• Pa11y: Command-line tool for automated accessibility testing

However, automated tools typically only catch about 30-40% of accessibility issues. They should be complemented with manual testing.

Manual Testing Techniques

Keyboard Navigation Testing

Test your entire site using only the keyboard:

1. Use Tab to navigate between interactive elements
2. Use Enter to activate links and buttons
3. Use space for checkboxes and some buttons
4. Use arrow keys for select dropdowns, radio buttons, and sliders

Screen Reader Testing

Test with actual screen readers:

• NVDA or JAWS (Windows)
• VoiceOver (Mac)
• TalkBack (Android)
• VoiceOver (iOS)

Focus on basic tasks like:

1. Navigating between pages
2. Completing forms
3. Understanding content structure
4. Interacting with custom components

Disability Simulation Testing

Use tools that simulate different disabilities:

• NoCoffee Vision Simulator: Chrome extension for vision impairment simulation
• Colour Contrast Analyser: For checking text against various colour vision deficiencies
• Funkify: Extension that simulates various disabilities including dyslexia and motor impairments

User Testing

Nothing replaces testing with actual users who have disabilities:

• Partner with local disability organisations in Ireland or the UK
• Consider remote accessibility testing services
• Create a diverse user testing panel that includes people with various disabilities

SEO Benefits of Accessible Websites

Accessibility and SEO share many best practices:

Structural Advantages

• Semantic HTML: Helps search engines understand content hierarchy and relationships
• Descriptive Link Text: Improves SEO while helping screen reader users understand destinations
• Proper Headings: Enhance both SEO and screen reader navigation
• Clean URL Structure: Benefits both SEO and text-to-speech pronunciation

Content Enhancement

• Image Alt Text: Provides context for search engines while making images accessible
• Transcripts and Captions: Make media content indexable by search engines
• Structured Data: Improves search visibility while potentially enhancing screen reader context

Technical Improvements

• Mobile Responsiveness: Essential for both SEO and accessibility
• Page Speed: A factor in search rankings that also improves usability for those with slow connections
• Clean Code: Improves crawlability for search engines and compatibility with assistive technologies

Research indicates that websites implementing WCAG guidelines often see a 15-20% improvement in organic search traffic due to these overlapping benefits.

Measuring Impact

Measuring the impact of accessibility-first web design is essential for understanding its value and refining your approach. By tracking key metrics—such as user engagement, bounce rates, conversion improvements, and accessibility audit results—organisations can gain clear insights into how inclusive design benefits both users and business outcomes. This section explores practical ways to evaluate the effectiveness of your accessibility strategy and demonstrate its return on investment.

Key Performance Indicators

Track these metrics to measure the business impact of accessibility improvements:

• Accessibility Score Improvement: Track progress using automated tools like Lighthouse

Common Myths

Myth: “Accessibility is only for people with severe disabilities”

Reality: Accessibility benefits many people, including:

• Users with temporary impairments (e.g., broken arm)
• Older users with changing abilities
• People using devices in challenging environments (bright sunlight, noisy settings)
• Mobile users with limited bandwidth or small screens

Myth: “Accessible websites are ugly and limiting”

Reality: Modern accessible websites can be visually appealing and feature-rich. Accessibility guidelines don’t prohibit advanced features—they simply ensure these features are usable by everyone.

Myth: “Accessibility compliance is expensive and time-consuming”

Reality: While retrofitting an inaccessible site can be costly, building accessibility in from the start adds minimal overhead. Many accessibility features require no additional development time when incorporated as standard practice.

Myth: “We don’t have users with disabilities”

Reality: With approximately 1 in 5 people in the UK having some form of disability, virtually every business has users with accessibility needs—whether they’re aware of it or not. Many users with disabilities won’t complain about inaccessible sites; they simply leave.
