How to Create a Checklist for Website Accessibility

Creating an accessible website is not just a matter of inclusivity, it is also essential for improving user experience, expanding your audience, and adhering to legal requirements in many countries. Website accessibility ensures that all users, including those with disabilities, can access, navigate, and interact with your website effectively.

This guide will walk you through the process of creating a comprehensive checklist for website accessibility. Whether you are a developer, designer, or content creator, this actionable guide will help you ensure your website is accessible to everyone.

Understand Accessibility Guidelines

Before creating your checklist, it's essential to familiarize yourself with the major accessibility guidelines. These guidelines, primarily the Web Content Accessibility Guidelines (WCAG), are the global standard for making web content accessible. The WCAG guidelines are organized into four principles:

• Perceivable: Information must be presented in ways that users can perceive.
• Operable: Users must be able to navigate and interact with the content.
• Understandable: Content must be presented in a way that is easy to understand.
• Robust: The content must work well with current and future technologies.

You can refer to WCAG 2.1 (the latest version) to ensure your website meets these criteria. Additionally, familiarize yourself with other laws and guidelines relevant to your country, such as the Americans with Disabilities Act (ADA) in the U.S., or the Equality Act in the UK.

Visual Accessibility

Visual accessibility involves ensuring that your website's design accommodates users with visual impairments. Below are some key points to consider when creating your checklist:

Actionable Steps:

• Contrast Ratios: Ensure there is sufficient contrast between text and background colors. WCAG 2.1 recommends a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (18pt or 14pt bold).
• Text Resizing: Users should be able to resize text up to 200% without losing content or functionality. Test your website by zooming in to ensure readability.
• Color Blindness: Avoid relying on color alone to convey important information. Use text labels, patterns, or shapes in conjunction with colors to ensure clarity for users with color blindness.
• Images and Graphics : Provide alternative text (alt text) for all images and graphical elements. The alt text should describe the content and function of the image accurately.
• Accessible Forms: Label elements within forms clearly, using HTML for proper structure. Ensure form controls have text descriptions or labels that are readable by screen readers.

Keyboard Accessibility

Many users with disabilities rely on keyboard navigation instead of a mouse. To make your website fully accessible, all interactive elements must be operable using only a keyboard.

Actionable Steps:

• Focus Management: Ensure that the tab order is logical and intuitive, with a focus indicator visible at all times. This allows users to navigate through interactive elements, such as links, buttons, and forms, in a predictable manner.
• Skip Navigation Links: Provide users with a way to skip repetitive content (like menus and headers) using a "skip to content" link.
• Accessible Controls: Interactive elements (e.g., buttons, forms, sliders, and menus) should be operable using the keyboard alone. This includes ensuring that they can be activated using the "Enter" or "Space" key, and that they can be navigated using the "Tab" key.
• Custom Widgets: If your website includes custom widgets (like carousels or modal dialogs), ensure that they are fully accessible by keyboard and that focus is appropriately managed when interacting with them.

Audio and Video Accessibility

Audio and video content are essential elements of many modern websites, but for users with hearing impairments, these elements can present a barrier. Ensuring that audio and video content is accessible is a critical part of any accessibility checklist.

Actionable Steps:

• Captions and Subtitles: Provide captions for all video content. Captions should accurately transcribe spoken dialogue and other relevant sounds. Additionally, consider offering subtitles in multiple languages.
• Transcript for Audio: For audio content (e.g., podcasts or voiceovers), provide a transcript. This ensures that users who are deaf or hard of hearing can access the content.
• Audio Control: Allow users to control audio content. For example, provide a "mute" button and allow users to adjust the volume.
• No Auto-Play: Avoid using auto-play for videos and audio. If auto-play is necessary, ensure users can easily pause or stop the media.

Screen Reader Compatibility

Screen readers are tools that convert text and other visual elements into speech or braille for users with visual impairments. To make your website accessible, you need to ensure that it is fully compatible with screen readers.

Actionable Steps:

• Semantic HTML: Use proper HTML elements (e.g., headings, lists, links, and forms) to create a clear document structure. Screen readers rely on semantic HTML to navigate the page correctly.
• ARIA (Accessible Rich Internet Applications) : Use ARIA roles and properties where necessary to enhance accessibility. For instance, use aria-label to describe elements that don't have visible text labels.
• Landmark Roles : Use landmark roles like header, main, footer, and nav to help screen reader users quickly navigate different sections of the page.
• Accessible Links and Buttons: Ensure that all links and buttons have descriptive text or accessible labels. Avoid using vague terms like "click here."

Mobile Accessibility

With the increasing use of mobile devices, ensuring mobile accessibility is more important than ever. Accessibility should extend across all platforms, whether users are on desktop computers, tablets, or smartphones.

Actionable Steps:

• Responsive Design: Ensure that your website is designed to work on a variety of devices and screen sizes. Responsive design ensures that content adapts to the screen, providing a consistent experience across platforms.
• Touchscreen Usability: Ensure that interactive elements are easy to tap on mobile devices. Elements should be large enough to be selected without errors.
• Mobile Keyboard Navigation: Ensure that keyboard navigation is functional on mobile devices as well. Test to ensure that forms and buttons are usable on both desktop and mobile versions of the site.
• Avoid Flash: Avoid using Flash-based content or ensure that alternatives are provided. Flash is not accessible to many users, particularly those with disabilities.

Testing and Validation

Creating an accessible website is an ongoing process, and testing is a crucial part of ensuring your site meets accessibility standards. Regular testing helps identify issues early and ensures that your website remains accessible as you add new content or features.

Actionable Steps:

• Automated Accessibility Tools : Use tools like WAVE , axe , or Lighthouse to scan your website for common accessibility issues. These tools can help you identify missing alt text, insufficient contrast, and other common problems.
• Manual Testing: Automated tools can identify some issues, but they cannot catch everything. Manually test your site by navigating it with a keyboard, screen reader, and other assistive technologies.
• User Testing: If possible, conduct user testing with people who have disabilities. This real-world testing can provide valuable insights into how accessible your website truly is.
• Continuous Monitoring: Make accessibility testing part of your ongoing website maintenance process. As you update your site with new content or features, always check for accessibility.

Conclusion

Creating a comprehensive checklist for website accessibility is essential for ensuring that your site is usable by everyone, regardless of their abilities. By following the actionable steps outlined in this guide, you can ensure your website is accessible to a wide range of users and compliant with important accessibility standards.

Remember, accessibility is not a one-time task but an ongoing process. Regular testing and continuous improvement will ensure that your website remains usable and accessible as technologies and user needs evolve.
