Semantic HTML5 Elements

Semantic HTML5 elements provide meaning to web content beyond mere presentation. They help in creating accessible and search engine friendly web pages by clearly defining the structure and purpose of different parts of web content.

Common Semantic HTML5 Elements

Semantic elements in HTML5 are those that clearly describe their meaning in a human- and machine-readable way. Elements such as <article>, <aside>, <details>, <figcaption>, <figure>, <footer>, <header>, <main>, <mark>, <nav>, <section>, <summary>, and <time> not only help in structuring the content but also define its purpose on the web page.

Tag	Description
