There are various accessibility issues on the website that hinder user experience, particularly for users relying on assistive technologies.
The website has several accessibility issues that can hinder user experience, particularly those relying on assistive technologies. These issues violate accessibility standards and can lead to a poor user experience.

## Description

The following accessibility issues were detected using an accessibility tool:

### Resolved
- #822
- ✅ **Document language not identified:** Affects how screen readers interpret content.
- ✅ **Image alternative text is missing:** Alt text is essential for users who rely on screen readers.
Skipped heading levels: Disrupts content hierarchy, making it harder for assistive technologies to navigate.
- ✅ **A link contains no text:** Links should have meaningful text to describe their purpose.
- ✅ **Form control missing labels:** Labels are crucial for screen readers and user understanding.
- ✅ **Form labels not correctly associated with controls:** Proper association helps assistive tech convey information.
- #838
- ✅ **Low contrast between text and background:** Poor contrast makes text hard to read, particularly for visually impaired users.

### Pending resolution
- #802
- ✅ **Adjacent links lead to the same URL:** Creates redundancy and confusion.

## Alternatives
Conducting a comprehensive accessibility audit and implementing automated and manual testing can help identify and fix issues systematically. Promptly addressing these specific issues will enhance user experience for all visitors, especially those with disabilities.
