**Some steps to implement this enhancement-**

- Determine the relevant ARIA attributes to add for each form element.
- Add ARIA roles to the forms and their elements (e.g., "form" role for the main form element).
- Include concise and descriptive ARIA labels using the aria-label attribute.
- Use the aria-describedby attribute to provide additional instructions for the forms.
- Implement ARIA states and properties (e.g., aria-required for required fields).
