HTML Semantic Tags

🧠 HTML Semantic Tags

Semantic tags in HTML provide meaningful structure to web content by clearly indicating the role of different parts of a webpage. Unlike generic tags like <div> and <span>, semantic tags enhance accessibility, SEO, and code clarity.

❓ What Are Semantic Tags?

Semantic tags describe the purpose of the content they contain.

For example:

• <article> – Independent piece of content
• <footer> – Section/page footer

They help:

• 🕵️ Search engines understand structure
• 🦯 Screen readers improve navigation
• 👨‍💻 Developers organize code logically
