Creating an accessible website is a must for any web designer and website owner in the modern age. An accessible website is one that can be used by as many people as possible including those with disabilities. Accessible sites are all inclusive designs that let everyone view and enjoy the access on websites. Below we have compiled a list of the basics you need to understand, best practices and simple steps you can take for the best website accessibility.

What is Web Accessibility?

Web accessibility means that websites, tools, and technologies are designed and developed so that people with disabilities can use them. More specifically, web accessibility encompasses all disabilities that affect access to the web, including auditory, cognitive, neurological, physical, speech, and visual disabilities [1].

Key Principles of Web Accessibility

1. Keyboard Navigation

Ensuring that all website functionalities can be accessed via keyboard alone is crucial. This allows users who cannot use a mouse due to mobility impairments to navigate and interact with web content. Implementing focus indicators and ensuring all interactive elements are keyboard accessible is a good practice [4].

Implementation Tips:

  • Use tabindex to manage keyboard navigation order.
  • Ensure all form elements, links, and interactive content are accessible via the keyboard.
  • Highlight focused elements clearly using CSS.

2. Readable and Understandable Content

Content should be clear and straightforward. Using plain language, providing text alternatives for non-text content, and logically structuring information helps users with cognitive impairments and those who rely on screen readers. Semantic HTML elements like headings, lists, and landmarks enhance both accessibility and SEO [3].

Implementation Tips:

  • Use semantic HTML tags like <header>, <nav>, <main>, <section>, and <footer>.
  • Provide text alternatives for images using alt attributes.
  • Ensure headings (<h1>, <h2>, etc.) follow a logical structure.

3. Visual Accessibility

To make content easy to see, ensure sufficient color contrast between text and background. Use scalable fonts and avoid using images of text. These practices benefit users with visual impairments, including color blindness and low vision [4].

Implementation Tips:

  • Use tools like the WebAIM Contrast Checker to ensure adequate color contrast.
  • Implement responsive design principles to make text scalable.
  • Avoid using images of text; use actual text instead.

4. Hearing Accessibility

Providing text transcripts and captions for audio and video content is essential for users who are deaf or hard of hearing. This practice ensures that multimedia content is accessible to a wider audience [4].

Implementation Tips:

  • Use services like YouTube’s automatic captions and then manually correct errors.
  • Provide downloadable transcripts for audio content.
  • Use descriptive video services to narrate visual content for users with visual impairments.

Best Practices for Designing Accessible Websites

1. Follow WCAG Guidelines

The Web Content Accessibility Guidelines (WCAG) provide a comprehensive framework for making web content more accessible to people with disabilities. These guidelines cover a wide range of recommendations, including text alternatives, adaptable content, distinguishable content, and navigable interfaces [5].

Implementation Tips:

  • Follow WCAG 2.1 standards, aiming for at least AA compliance.
  • Regularly review updates to WCAG for new best practices and guidelines.

2. Use Semantic HTML

Proper use of HTML elements enhances the accessibility of your website. Semantic HTML tags like <header>, <nav>, <main>, <section>, and <footer> help screen readers understand the structure and hierarchy of the content [3].

3. Test Accessibility

Regularly test your website’s accessibility using tools like WAVE, Axe, or Lighthouse. These tools can identify accessibility issues and provide recommendations for improvements. Involving users with disabilities in the testing process can provide valuable insights into real-world usability [5].

Implementation Tips:

  • Perform automated accessibility testing using tools like WAVE and Axe.
  • Conduct manual testing with users who have disabilities to gather qualitative feedback.
  • Integrate accessibility testing into your regular development workflow.

For examples of accessible websites have a look at the work of Meath Web Design.

4. Provide Multiple Ways to Navigate

Include various navigation options such as a search bar, site map, and clear menu structure. This helps users find content more easily and accommodates different browsing preferences. Ensure that all navigational elements are accessible via keyboard and screen readers [2].

Implementation Tips:

  • Implement a skip navigation link to help keyboard users bypass repetitive content.
  • Ensure the search functionality is accessible and easily discoverable.
  • Provide a clear and consistent navigation structure across all pages.

Examples of Accessible Websites

BBC

The BBC website is a leading example of accessibility, offering extensive features for users with disabilities. The site includes high-contrast modes, keyboard navigation, and well-structured content, making it accessible to a broad audience [6].

Gov.uk

The UK government’s website is designed with accessibility in mind, ensuring that all citizens can access public services online. The site follows best practices for accessibility, including clear navigation, text alternatives for non-text content, and consistent structure [6].

Additional Examples

Apple

Apple’s website is well-known for its focus on accessibility, providing features like screen reader compatibility, voiceover support, and keyboard navigation. These features ensure that the site is usable by people with various disabilities.

Microsoft

Microsoft’s website offers a comprehensive set of accessibility features, including high-contrast modes, keyboard shortcuts, and compatibility with assistive technologies. The company also provides extensive resources on making software and content accessible.

Emerging Trends in Web Accessibility

1. ARIA Landmarks

ARIA (Accessible Rich Internet Applications) landmarks help improve navigation for screen reader users by defining sections of a webpage, such as the main content, navigation, and complementary content. Implementing ARIA landmarks can enhance the user experience for people with disabilities [5].

2. Voice User Interface (VUI)

Voice user interfaces are becoming increasingly popular, allowing users to interact with websites and applications using voice commands. This trend is particularly beneficial for users with mobility impairments or visual disabilities.

3. AI-Powered Accessibility Tools

Artificial intelligence is being used to develop new accessibility tools, such as automatic image descriptions, real-time captioning, and personalized accessibility settings. These tools can help make web content more accessible to a wider audience.

Conclusion

Making websites accessible is not only a legal requirement in many regions but also an ethical responsibility. By following best practices and guidelines, web designers and developers can create inclusive digital environments that serve all users, regardless of their abilities. Implementing web accessibility improves user experience, broadens audience reach, and enhances overall site effectiveness.

By adding implementation tips, emphasizing user testing, and including more detailed guidance, this guide now provides a comprehensive, actionable resource for designing accessible websites.
