This document outlines the acceptance criteria as a checklist for implementing WCAG 2.2 standards and provides examples to ensure clear evaluation. By adhering to these guidelines, we aim to make our project accessible to a wide range of users, including those with disabilities. More information can also be found in Standard Implementation Documentation.

• Alt Text for Non-Text Content

  • All images and icons must include appropriate alternative text that conveys their purpose or content.
  • Examples:

    <img src="profile.jpg" alt="Profile picture of John Doe">
    <img src="tag.png" alt="The logo image of Python" title="Python logo">

• Use of Color & Color Contrast

  • Color contrast should ensure that text is legible against its background, particularly for users with visual impairments.
  • Example: Updating text with low contrast

       --   <p className="line-clamp-3 text-sm font-light text-gray-600">
       ++   <p className="line-clamp-3 text-sm font-light text-gray-800">

• ARIA Labeling for Buttons

  • Buttons should have clear labels describing their action.
  • Example: Submit form aria label

  <button aria-label="Submit form">Submit</button>

• Screen Reader

  • Each icon should have a screen reader-only text.
  • Example: sr-only for icons.

    <a href="#">
    <svg><!-- ... --></svg>
    <span class="sr-only">Links to official website</span>
    </a>

---

• Keyboard Accessibility
  • All interactive elements must be navigable using keyboard inputs, with proper focus indication.
  • Example: Skip link functionality to allow users to jump to main content

  <a
        href="#main-content"
        className="sr-only focus:not-sr-only focus:fixed focus:z-50 focus:block focus:bg-background focus:p-4"
      >
        Skip to main content
      </a>

---

• Clear Instructions

  • Provide concise and clear instructions for completing forms or interacting with components.
  • Example:

    <label for="email">Email Address:</label>
    <input type="email" id="email" required>
    <span class="hint">Please enter a valid email address.</span>

• Error Identification and Suggestions

  • Highlight errors clearly and provide actionable suggestions.
  • Example:

    <div role="alert" class="error">
      Error: Password must be at least 8 characters long.
    </div>

---

• Assistive Technology Compatibility

  • Ensure compatibility with screen readers and other assistive tools by adhering to ARIA standards.
  • Example:

    <div role="tablist" aria-orientation="horizontal">
      <button role="tab" aria-selected="true" aria-controls="panel1">Tab 1</button>
    </div>

• Automated Testing for Accessibility

  • Include automated tests to verify compliance.
  • Example:

    it("should have proper ARIA attributes", () => {
      const tablist = screen.getByRole("tablist");
      expect(tablist).toHaveAttribute("aria-orientation", "horizontal");
    });

This document ensures our WCAG 2.2 implementation aligns with accessibility standards. Each criterion includes examples and evaluation methods to facilitate consistent compliance and foster inclusivity.
