Which four areas must be assessed when converting a site to 508 compliance?

When converting a site to Section 508 compliance, four key areas must be assessed:

1. Accessibility of Content: Ensure that all text, images, and multimedia content are accessible, including the use of alternative text for images and captions for videos.
2. Navigation: Verify that the website is navigable via keyboard and that all links and forms are properly labeled for screen readers.
3. Semantic HTML Structure: Check the use of proper HTML markup to ensure that headings, lists, and tables are correctly structured for assistive technologies.
4. Color Contrast and Visual Elements: Assess color contrast to ensure readability and ensure that visual elements convey information without relying solely on color.
