Semantic elements in HTML5 are special tags that provide meaning and structure to the content of a web page. They help both browsers and developers understand the type and purpose of the content. Some common semantic elements include <header>, <nav>, <section>, <article>, <footer>, <aside>, and <main>. These elements are more descriptive than generic <div> tags and assist in creating well-structured, accessible, and SEO-friendly web pages.

Semantic elements in HTML5 are a set of tags designed to give meaning and structure to the content of a web page. They play a crucial role in improving the accessibility and search engine optimization (SEO) of a website. Here are some key semantic elements: <header>, <nav>, <section>, <article>, <footer>, <aside>, and <main>.
In earlier days of web development, we primarily used generic <div> elements with IDs like <div id="header"> and <div id="footer"> to structure our web pages. While this approach worked, it lacked semantic meaning. With the introduction of semantic elements in HTML5, we gained a more structured and meaningful way to define these sections.
For example, instead of a generic <div id="header">, we can now use <header> to clearly indicate the introductory section of our webpage. Similarly, <footer> provides a more semantic representation of the footer section. These semantic elements not only make our HTML code cleaner but also improve accessibility and SEO by conveying the purpose and hierarchy of the content to both browsers and screen readers.
