Best Practices for Web Accessibility to Create Inclusive Digital Experiences

In the vast landscape of the internet, ensuring that websites are accessible to all users is not just a courtesy—it’s an imperative. Web accessibility involves designing and developing websites and applications that people with disabilities can use without barriers. This commitment to inclusivity does more than just widen your audience; it improves the user experience for everyone, boosts your site’s SEO, and aligns with legal standards that are increasingly being enforced around the globe.
Creating a website that everyone can navigate, understand, and interact with requires a unified approach from the entire development team. Designers, developers, content managers, and other stakeholders must work collaboratively to integrate accessibility principles from the very beginning of the project. This proactive approach helps prevent the significant costs associated with retrofitting websites and ensures compliance with the Web Content Accessibility Guidelines (WCAG), setting a global standard for accessibility.
This blog will delve into the crucial best practices for web accessibility and illustrate how collaborative efforts can lead to creating truly inclusive digital experiences. By understanding and implementing these practices, your team can build websites that are not only accessible but also exemplary in their functionality and design.
Best Practices for Web Accessibility to Create Inclusive Digital Experiences

Understanding Accessibility Standards

To create an accessible website, it’s crucial to start with a clear understanding of the international standards that define what accessibility means in a digital context. The Web Content Accessibility Guidelines (WCAG) are the cornerstone of web accessibility efforts globally. These guidelines are developed by the World Wide Web Consortium (W3C) and provide a framework for making web content more accessible to people with disabilities, including auditory, cognitive, neurological, physical, speech, and visual disabilities.

The Core Principles of WCAG

WCAG guidelines are built around four principles that assert that web content must be:
  • Perceivable: Information and user interface components must be presentable to users in ways they can perceive. This means that users must be able to perceive the information being presented (it can’t be invisible to all of their senses).
  • Operable: User interface components and navigation must be operable. This principle ensures that all users can operate the interface (the interface cannot require interaction that a user cannot perform).
  • Understandable: Information and the operation of the user interface must be understandable. Users must understand the information and the operation of the user interface (the content or operation cannot be beyond their understanding).
  • Robust: Content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies. Users must be able to access the content as technologies advance.

Levels of Compliance

WCAG guidelines are categorized into three levels of compliance:
  • Level A (minimum level): The most basic web accessibility features, which must be satisfied for some users to be able to use the web content.
  • Level AA (mid-level): Deals with the biggest and most common barriers for disabled users.
  • Level AAA (highest level): The highest level of accessibility and the most difficult to achieve.

Why Compliance Matters

Adhering to these standards is important not only to avoid legal repercussions in many regions but also to ensure that your website provides a positive user experience for all visitors. By following WCAG guidelines, web developers and designers can create more inclusive digital environments that cater to a wider audience, thereby enhancing the site’s usability and reach.
In the next sections, we’ll explore how different roles within a web development team can contribute to meeting these accessibility standards, starting with designing for accessibility.

Designing for Accessibility

When designing websites, incorporating accessibility from the start is not only beneficial for users but also cost-effective for businesses. A well-thought-out accessible design can prevent major overhauls later and ensure that your website reaches a broader audience. Here are some key practices and tools that can help designers create more inclusive digital experiences.

Essential Design Considerations

  • Color and Contrast: Ensure sufficient contrast between text and background colors to help users with visual impairments. Tools like the WebAIM Color Contrast Checker can guide you to comply with WCAG standards for contrast.
  • Use of Fonts: Choose fonts that are easy to read and size them appropriately. Avoid using small font sizes and elaborate typefaces that can be difficult to decipher. Aim for a clear, consistent hierarchy in text for better understanding.
  • Intuitive Navigation: Design navigation that is easy for all users to understand and use. This includes clear labels, consistent navigation patterns, and interactive elements that are easy to identify.
  • Alternative Text for Images: Always provide alt text for images. This text should clearly describe the image’s content or function, which is crucial for screen reader users and in situations where images cannot be displayed.

Tools for Designing Accessibility

  • Sketch and Adobe XD Plugins: Use plugins designed to simulate color blindness or to check color contrast directly within design tools like Sketch or Adobe XD.
  • Inclusive Design Toolkits: Utilize resources like Microsoft’s Inclusive Design Toolkit, which offers guidelines and best practices for creating more accessible designs.

Collaborative Practices

  • Work Closely with Developers: Ensure that the design elements can be translated into code. Regular collaboration between designers and developers can help identify potential accessibility issues early in the design phase.
  • Involve Users with Disabilities in User Testing: Conduct usability tests with participants who have disabilities to get direct feedback on how accessible your designs are. This can provide invaluable insights into the practical implementation of your designs.
By prioritizing accessibility in the design phase, you can create websites that are not only compliant with legal standards but also more welcoming and usable for everyone. This approach not only enhances user satisfaction but also positions your brand as inclusive and socially responsible.

Developing with Accessibility in Mind

When it comes to building websites, developers play a crucial role in ensuring that accessibility is woven into the fabric of the digital experience. Integrating accessibility during the development phase not only meets compliance requirements but also enhances usability for all users. Here’s how developers can incorporate accessibility into their coding practices:

Fundamental Development Practices

  • Semantic HTML: Use HTML according to its intended purpose. Proper use of HTML elements like <header>, <footer>, <article>, and <nav> helps communicate the structure of the webpage to assistive technologies. This includes using <button> elements for buttons instead of divs styled to look like buttons, which ensures that these elements are accessible to screen readers and keyboard users.
  • ARIA (Accessible Rich Internet Applications): Utilize ARIA roles and properties to enhance accessibility when native HTML elements cannot achieve the desired level of accessibility. ARIA attributes can make dynamic content and complex user interface controls accessible to people with disabilities.
  • Keyboard Navigation: Ensure that all interactive elements are accessible via the keyboard. This is crucial for users who cannot use a mouse and rely on keyboard navigation. Elements should be focusable and interactive elements should have visible focus styles to indicate where the keyboard focus is on the page.
  • Error Handling and Feedback: Provide clear and immediate feedback for actions. For example, if a user fails to fill out a form field correctly, ensure that the error message is descriptive and helpful. Errors should be programmatically associated with their respective controls so that screen reader users are aware of them.

Tools for Developing Accessibility

  • Automated Testing Tools: Utilize tools like Axe or Lighthouse to perform accessibility audits. These tools can identify many common accessibility issues, such as missing alt text or insufficient color contrast.
  • Browser Extensions: Extensions such as WAVE (Web Accessibility Evaluation Tool) can be added to browsers to quickly check the accessibility of a webpage during the development phase.

Collaborative Development Strategies

  • Regular Code Reviews: Implement accessibility checks as part of the code review process. Having another set of eyes check for accessibility issues can help catch problems that the original developer may have missed.
  • Continuous Learning and Training: Stay updated with the latest accessibility guidelines and practices. Regular training sessions for the development team can help ensure that everyone is aware of best practices and new techniques in accessible web development.
By integrating these development practices, developers not only adhere to legal and ethical standards but also contribute to creating a more inclusive digital world. This commitment to accessibility ensures that websites are usable and enjoyable for everyone, regardless of their abilities or disabilities.

Content Strategy for Accessibility

Creating content that is accessible is pivotal for ensuring that all users, regardless of their abilities, can understand and engage with your website. Content creators, including writers, video producers, and graphic designers, must adopt practices that make their output both perceivable and operable by everyone. Here’s how to integrate accessibility into your content strategy:

Accessible Text Content

  • Clear and Simple Language: Use plain language to communicate information. Avoid jargon, overly complex sentences, and idiomatic expressions that might confuse readers, including those with cognitive disabilities.
  • Structured Headings: Use proper heading levels (H1, H2, H3, etc.) to structure your content. This helps users with screen readers navigate through the sections and understand the hierarchy and organization of the page.
  • Descriptive Link Text: Avoid vague link descriptions like “click here.” Instead, use descriptive link texts that convey the link’s purpose when read out of context.

Accessible Multimedia

  • Alt Text for Images: Provide concise and descriptive alt text for all images. This text should convey the content and function of the image, helping those who cannot see them understand their context.
  • Subtitles and Captions for Videos: Include subtitles or captions for video content, catering to users who are deaf or hard of hearing. Transcripts also help users who prefer to read rather than watch a video.
  • Audio Descriptions: Offer audio descriptions for video content that contains important visual elements not explained by the audio alone. This practice is crucial for blind and visually impaired users.

Accessible Design Elements

  • Consistent Layout: Maintain a consistent layout across pages. Consistency in navigation and page design can help users with cognitive disabilities understand and predict how to find information.
  • Contrast and Color: Ensure that text contrasts sharply with the background. Avoid using color alone to convey information, as this practice can be problematic for users who are color blind.

Testing Content for Accessibility

  • User Testing: Regularly test your content with real users, including people with disabilities. This approach provides direct feedback on how accessible your content is and what improvements are necessary.
  • Automated Tools: Use automated tools to check the accessibility of your content. Tools like the WAVE Web Accessibility Evaluation Tool can help identify issues in web content that need to be addressed.
By embedding these accessibility principles into your content strategy, you ensure that your content is not only compliant with legal standards but also reaches a wider audience effectively. Accessible content is key to creating an inclusive digital environment that values all users equally.

Testing and Maintaining Accessibility

Ensuring that your website remains accessible is an ongoing process. Regular testing and maintenance are crucial to uphold accessibility standards as content updates, and technology changes. Here’s how to effectively test and maintain accessibility on your website:

Regular Accessibility Audits

  • Automated Testing Tools: Regularly use tools like Axe, Lighthouse, or WAVE to run automated tests that can quickly identify some common accessibility issues. These might include missing alt text, poor color contrast, or missing form labels.
  • Manual Testing: Automated tools can’t catch everything. Manual testing involves navigating your site using only a keyboard or using screen readers to experience how accessible your site truly is from a user perspective.

Involving Real Users

User Testing with People with Disabilities: Perhaps the most valuable method of testing, involve real users with various disabilities in your testing process. This direct feedback can provide insights into the practical challenges faced by these users and help you understand how to address them effectively.

Continuous Improvement

  • Respond to Feedback: RMake it easy for users to provide feedback on accessibility issues and be responsive to their concerns. This not only helps in fixing issues but also demonstrates your commitment to accessibility.
  • Stay Updated with Standards: Accessibility standards and best practices are continually evolving. Stay informed about the latest updates to standards like WCAG and implement changes as necessary.

Documenting and Monitoring Progress

  • Accessibility Documentation: Keep detailed records of your accessibility practices, including audits, user testing results, and training activities. This documentation can help you monitor progress and demonstrate compliance with legal requirements.
  • Monitoring Tools: Set up monitoring tools that can alert you to potential accessibility issues introduced by new updates or changes to the website.
