Accessibility: Improve search input accessibility with ARIA labels and descriptions

[abhijithm34]

Issue Description
The search input currently lacks proper accessibility attributes making it difficult for screen readers and keyboard users to navigate efficiently. Without ARIA labels and descriptions blind users may struggle to understand the purpose of the search field impacting their ability to explore content seamlessly. This issue affects accessibility compliance and overall user experience particularly for those relying on assistive technologies.

Proposed Solution

• Add aria-label="Search articles" to provide clear identification for screen readers
• Use aria-describedby to link a help text that explains search functionality and available options
• Ensure proper association between the input field and its corresponding help text for better usability

Benefits

• Enhances screen reader compatibility making navigation easier for blind and visually impaired users
• Improves keyboard accessibility ensuring all users can interact with the search function efficiently
• Aligns with accessibility standards such as WCAG fostering a more inclusive experience

Implementation

• Add appropriate ARIA attributes to the search input field
• Include a clear descriptive help text to assist users
• Maintain existing functionality while significantly improving accessibility
