HTML5 semantic tags are crucial for several reasons, primarily enhancing accessibility, improving search engine optimization (SEO), and facilitating clearer code structure and maintenance.
Enhancing Accessibility
Semantic tags provide specific meanings to the content they enclose, which helps assistive technologies like screen readers interpret the page content correctly.
