Final answer:
508 standards require marking up data cells and header cells for accessibility purposes, which aligns with WCAG guidelines. This makes websites more usable for people with disabilities.
Step-by-step explanation:
The 508 standards pertain to web accessibility and require that markup be used to associate data cells and header cells for accessibility. This is essential to ensure that websites are usable by people with disabilities, including those who use screen readers. By following these standards, web content creators can provide more accessible content that aligns with the Web Content Accessibility Guidelines (WCAG).
LibreTexts™ provides an example of adhering to these accessibility standards, by ensuring proper headings, a high contrast ratio between text and background, descriptive alt text for images, and hyperlinks that open in the same window to facilitate navigation for users with disabilities.
