The best way to structure semantic HTML landmarks for web accessibility is replacing generic divs with native elements like header, nav, main, section, article, and footer to enforce standards-compliant structure by default.

Fix improper heading order and missing alt text in JSX by enforcing semantics-first structure and built-in accessibility guidelines. This ensures proper heading hierarchy and meaningful image descriptions across your project.
