A website accessibility checklist serves as your primary guide for ensuring that digital content remains usable for people with disabilities. By following WCAG 2.2 standards, businesses ensure their interfaces provide equal access to all users. These technical requirements cover design, development, and content structure. Addressing these items helps mitigate legal risks and improves the overall quality of your digital presence for every visitor.
What is the WCAG 2.2 standard and why does it matter?
The Web Content Accessibility Guidelines (WCAG) 2.2 were published in October 2023. These guidelines represent the current global benchmark for web accessibility. They provide a specific framework to measure if a digital product can be used effectively by those relying on assistive technology. Adhering to these standards is no longer just a best practice for inclusive design.
Legal landscapes are shifting rapidly across international borders. For example, the European Accessibility Act applies from June 2025, mandating that many private sector websites meet strict accessibility criteria. Ignoring these updates can lead to significant compliance gaps for businesses operating internationally. An Alien Road audit often reveals that minor adjustments to code and design can bring a site into alignment with these updated requirements.
How do you ensure proper visual contrast on your pages?
Visual contrast is the most frequent point of failure in standard web design. The WCAG 2.2 requirement specifies a contrast ratio of at least 4.5:1 for standard text against its background. This ensures that users with low vision or color blindness can distinguish characters from the surrounding area. High contrast settings are not just for accessibility; they often improve readability for everyone in bright environments.
You should verify contrast in your CSS files or CMS theme settings. When designing a new landing page, check that your brand colors meet this 4.5:1 threshold. If your current palette fails, consider modifying the shade or adding a dark overlay behind text elements. Do not rely on color alone to convey meaning, as this creates barriers for those who cannot perceive specific hues.
Critical technical steps for your accessibility checklist
- Implement alt text for all non-decorative images to describe content for screen reader users.
- Ensure all interactive elements have a focus visible state that is clearly identifiable when navigating via keyboard.
- Verify that target sizes for buttons and links are large enough to be activated easily, reducing accidental clicks.
- Structure your HTML using proper header tags (H1 through H6) to create a logical document hierarchy.
- Ensure all form fields have descriptive labels that persist when the field is selected.
- Test keyboard navigation to confirm that every element reachable by a mouse can also be accessed without one.
Why is keyboard navigation essential for compliance?
Many users rely on keyboards or switch devices rather than a mouse to move through a website. A focus visible indicator is the primary tool these users have to track their current location on a page. If the outline disappears when a user tabs through your menu, they lose their place instantly. This behavior is a common barrier that prevents successful navigation.
When developers write CSS for interactive components, they often use the outline: none property to remove browser default styles. This is a practice to avoid. Instead, use the focus-visible pseudo-class to style your own clear, high-contrast borders for focused items. This small change ensures that keyboard users always know exactly which link or button they are about to activate.
How to handle image content and alt text?
Alt text provides a text-based alternative for visual content. Screen readers read this text aloud, allowing users with visual impairments to understand the context of an image. When writing alt text, focus on the function or the information conveyed by the visual. If an image is purely decorative, such as a background swirl, use an empty alt attribute to allow screen readers to ignore it.
In a typical account, marketers often forget to update alt text when swapping promotional banners. Make it a habit to include alt text requirements in your content creation workflow. If you are using a CMS like WordPress, enter the description in the media library settings. This ensures that every image uploaded to your site automatically carries its accessibility metadata, reducing the need for manual updates later.
The importance of target size in mobile layouts
Target size refers to the physical dimensions of touchable elements like buttons and links. Small targets are difficult for users with motor impairments to activate accurately. WCAG 2.2 emphasizes that these targets must be large enough to minimize errors. While the exact requirements depend on the context, ensuring a comfortable gap between buttons is a highly effective way to comply.
Review your mobile navigation menu and primary call-to-action buttons. If buttons are placed too close together, a user might accidentally tap the wrong link. Increase the padding around your buttons in your style sheet to expand the clickable area without necessarily changing the visual size of the button itself. This simple CSS adjustment helps users maintain control while browsing on touch devices.
Accessibility checklist maintenance plan
- Audit existing image alt text across your primary landing pages.
- Use a browser inspection tool to check the contrast ratio of your primary text against the background.
- Navigate your homepage using only the ‘Tab’ key to check for focus indicators.
- Review your mobile button layouts to ensure they provide enough space for easy tapping.
- Add a recurring reminder to check your accessibility status every quarter.
- Ensure all new video content includes captions to support hearing-impaired users.
Where to start this week
Start your accessibility journey by identifying the top three most-visited pages on your site. These pages represent the majority of your user interactions. Run a basic keyboard-only navigation test on these pages to identify immediate gaps in focus visibility. If your navigation menu disappears or the focus indicator is invisible, prioritize those fixes first.
Second, check your color contrast on these specific pages. If your primary text fails the 4.5:1 ratio, update your CSS style definitions to improve legibility. Finally, document your progress in a simple spreadsheet. This log serves as your evidence of consistent effort, which is useful when preparing for the June 2025 compliance deadlines. Taking these small, deliberate steps will significantly improve your site for every visitor.
