What is the purpose of semantic HTML?

• A. To optimize for search engine indexing.
• B. To replace CSS for styling.
• C. To describe the structure and meaning of content for browsers and assistive technologies.
• D. To define presentation and layout only.

Answer: (C)

Semantic HTML aims to describe the structure and meaning of content for browsers and assistive technologies. By using elements that indicate purpose—such as header for the page header, nav for navigation, main for the main content, article for a standalone piece, section for a thematic group, aside for related or tangential content, and footer for the page footer—you convey how the page is organized. This makes it easier for screen readers and other assistive tech to navigate, interpret, and present the content to users, and it helps search engines understand the page’s meaning more accurately. It also supports maintainability and reusability of markup. This isn’t about replacing CSS or defining presentation; styling remains the job of CSS, while semantic HTML focuses on meaning rather than how things look.
