Semantic HTML

What is Semantic HTML?

Semantic HTML refers to the use of HTML markup that conveys meaning about the content contained within it. Instead of using generic tags such as <div> or <span>, semantic HTML employs tags that describe the content and its role within the document structure, such as <header>, <article>, and <footer>.

Importance of Semantic HTML

Using semantic HTML is crucial for several reasons:

Improves accessibility for screen readers and other assistive technologies.
Enhances SEO as search engines can better understand the structure and content of the page.
Facilitates better maintainability of code, making it easier for developers to understand the purpose of each section.

Common Semantic Elements

Here are some commonly used semantic HTML elements:

<header> - Represents introductory content or a group of navigational links.
<nav> - Defines a set of navigation links.
<article> - Represents a self-contained composition in a document.
<section> - Defines a section in a document, which can contain multiple articles.
<footer> - Represents the footer for a section or page.
<aside> - Defines content that is related to the main content but can stand alone.
<main> - Represents the dominant content of the <body>.
<figure> - Represents self-contained content, like an image with a caption.
<figcaption> - Provides a caption for the <figure>.

Best Practices

To effectively use semantic HTML, consider the following best practices:

Use the appropriate semantic tag for the content being presented.
Avoid using non-semantic elements (like <div>) when a semantic element is appropriate.
Ensure that your HTML structure is logical and follows a hierarchy.
Use ARIA roles only when necessary, as semantic elements already convey meaning.
