Breadcrumb Accessibility

Ensures breadcrumb components follow WCAG compliance and WAI-ARIA Breadcrumb Pattern specifications.

actions:

• type: enforce conditions:

  Navigation landmark requirement

  • pattern: "(?i)<nav[^>](?:breadcrumb|navigation)[^>]>" pattern_negate: "(aria-label|aria-labelledby)="[^"]+"" message: "Breadcrumb navigation must have aria-label or aria-labelledby attribute."

  Current page aria-current requirement

  • pattern: "(?i)<[^>]*(?:breadcrumb.*current|current.breadcrumb)[^>]>" pattern_negate: "aria-current="page"" message: "Current page in breadcrumb must have aria-current='page' attribute."

  List structure requirement

  • pattern: "(?i)<nav[^>](?:breadcrumb|navigation)[^>]>" pattern_negate: "<ol[^>]*>" message: "Breadcrumb navigation should use ordered list (ol) for proper structure."

• type: suggest message: | Breadcrumb Component Accessibility Best Practices:

  Required ARIA Attributes:

  • aria-label/aria-labelledby: On navigation element to describe the breadcrumb trail
  • aria-current="page": On the current page link or element
  • role="navigation": Implicit on nav element, but can be explicit if needed

  Structure Requirements:

  • Use <nav> element as container
  • Use ordered list (<ol>) for breadcrumb items
  • Use list items (<li>) for each breadcrumb level
  • Current page should be the last item in the list
  • Use appropriate heading level for the breadcrumb container

  Implementation Patterns:

  Basic Breadcrumb:

  <nav aria-label="Breadcrumb">
    <ol class="breadcrumb">
      <li class="breadcrumb-item">
        <a href="/">Home</a>
      </li>
      <li class="breadcrumb-item">
        <a href="/products">Products</a>
      </li>
      <li class="breadcrumb-item" aria-current="page">
        <a href="/products/electronics">Electronics</a>
      </li>
    </ol>
  </nav>

  With aria-labelledby:

  <nav aria-labelledby="breadcrumb-heading">
    <h2 id="breadcrumb-heading" class="visually-hidden">Breadcrumb Navigation</h2>
    <ol class="breadcrumb">
      <li class="breadcrumb-item">
        <a href="/">Home</a>
      </li>
      <li class="breadcrumb-item" aria-current="page">
        <span>Current Page</span>
      </li>
    </ol>
  </nav>

  Accessibility Notes:

  • Navigation landmark helps screen readers identify the breadcrumb trail
  • Ordered list provides semantic structure for the navigation hierarchy
  • aria-current helps users identify their current location
  • Consider using visually-hidden text for better screen reader context
  • Ensure sufficient color contrast for all breadcrumb elements
  • Maintain clear visual separation between items
  • Use clear, descriptive labels for each level

  Testing Checklist:

  • Verify navigation landmark is present and properly labeled
  • Confirm ordered list structure is used
  • Check aria-current is present on current page
  • Test with screen readers to ensure proper announcement
  • Verify visual hierarchy is clear and consistent
  • Ensure all links are keyboard accessible
  • Check color contrast meets WCAG requirements
