Fix Accessibility Issues in Showcase Thumbnail Links

[huangkevin-apr]

Issue Description

When running IBM Accessibility Checker (Version 4.0.9) on the showcase page, multiple (49) violations were detected indicating that links in the showcase thumbnail component lack accessible names. This creates barriers for screen reader users who cannot understand the purpose of these links. The checker identified multiple instances of "Hyperlink has no link text, label or image with a text alternative" violations.

Solution

Added aria-label attribute to the link element in the ShowcaseThumbnail component, using showcase.name as the accessible label text. This ensures:

• Screen reader users can clearly understand the destination of each link
• Compliance with WCAG accessibility standards
• Improved overall user experience for assistive technology users

Fix Before:

There are 49 violations - "Hyperlink has no link text, label or image with a text alternative"

Violation Element Example:

<a href="https://cursor.com" target="_blank" rel="noopener noreferrer" class="absolute inset-0 z-10"></a>

Fix After:

All 49 violations have been resolved, use the aria-label attribute to point to text visible on the page that identifies the link purpose.

Fixed Violation Element Example:

<a href="https://cursor.com" target="_blank" rel="noopener noreferrer" class="absolute inset-0 z-10" aria-label="Cursor"></a>
