Semantic Web Page

Learn how to make the Web page semantic

---

The term Semantic element means an element with a meaning.

A semantic element clearly describes its meaning to both the browser and the developer.

Example: <form>, <table>, <article>, <main> tags clearly defines what its content will be.

However, the non-semantic elements like <div>, <span> tell nothing about its content.

Structure of Semantic web page

Important semantic elements

• The <header> element represents introductory content, or set of navigational links.
• The <nav> element defines a set of navigation links.
• The <main> specifies the main content of a document.
• The <section> element defines a section in a document.
• The <aside> element defines some content separate from the main content(like a sidebar).
• The <article> element specifies independent, self-contained content.
• The <footer> element defines a footer for a document or section.
• The <figure> tag specifies self-contained content, like illustrations, diagrams, photos etc.
