Semantic HTML

What is Semantic HTML?

Semantic HTML uses HTML elements that convey meaning, both to developers and browsers. Instead of using generic elements like <div> and <span>, semantic tags like <header>, <footer>, and <section> clarify the structure of the content.

Why It Matters: The Evolution of HTML

Early HTML (Pre-HTML5):

• Relied on <div> and <span> for layout.
• Made web pages difficult to read for both humans and machines.

Introduction of HTML5 (2014):

• Added semantic elements like <header>, <footer>, <article>, etc.
• Promoted cleaner and more accessible code.
• Improved machine readability and accessibility for users.

Benefits of Semantic HTML

Accessibility

• Assistive technologies like screen readers understand document structure with semantic tags.
• Tags help screen readers identify sections, enhancing the experience for users with disabilities.

SEO (Search Engine Optimization)

• Semantic tags help search engines interpret content structure and importance.
• Tags like <article> and <header> improve content hierarchy and rankings.
• <main>, <nav>, <header>, and other elements enhance context and relevance for search engines.

Clean Code Structure

• Semantic elements organize code logically, making it easier to read and maintain. Developers can quickly identify content sections, reducing coding errors and improving collaboration across teams.
