HTML Semantic Elements

Semantic HTML elements clearly describe the meaning of the content they contain. They help browsers, developers, and search engines understand the structure of a webpage. Semantic elements make websites easier to read, maintain, and improve accessibility for users.


Common Semantic Elements

HTML5 introduced several semantic elements that describe different parts of a webpage.

  • <header> - Defines the header section of a webpage.
  • <nav> - Defines navigation links.
  • <main> - Defines the main content of a webpage.
  • <section> - Defines a section of related content.
  • <article> - Defines independent content like articles or blog posts.
  • <aside> - Defines sidebar or additional information.
  • <footer> - Defines the footer section.
