2. Step-by-Step Guide
2.1 Understanding Semantic HTML
Semantic HTML is the use of HTML markup to reinforce the semantics, or meaning, of the information in webpages rather than merely to define its presentation or look. Semantic HTML is processed by traditional web browsers as well as by many other user agents like screen readers for visually impaired, search engines, etc.
2.2 Importance of Semantic HTML
Semantic HTML plays a crucial role in accessibility. Screen readers for visually impaired users rely on the semantic information to provide context and meaning to the content. Search engines also use semantics to understand and rank pages better.
2.3 Semantic Elements in HTML
HTML5 introduced a set of semantic elements. These include <header>, <footer>, <article>, <section>, <nav>, and <aside> among others.
3. Code Examples
Example 1: Using <header>, <footer>, and <nav>
<!-- This is the header of your webpage -->
<header>
<h1>Welcome to My Website</h1>
</header>
<!-- This is the navigation bar -->
<nav>
<a href="#home">Home</a> |
<a href="#blog">Blog</a> |
<a href="#contact">Contact</a>
</nav>
<!-- This is the footer of your webpage -->
<footer>
<p>Copyright © 2022 My Website</p>
</footer>
In the above code:
- The <header> element represents a container for introductory content or a set of navigational links.
- The <nav> element is used to define a set of navigation links.
- The <footer> element typically contains information about its section such as who wrote it, links to related documents, copyright data, and the like.
Example 2: Using <article> and <section>
<article>
<h2>My First Blog Post</h2>
<section>
<h3>Introduction</h3>
<p>This is the introduction to my first blog post...</p>
</section>
<section>
<h3>Main Content</h3>
<p>This is the main content of my blog post...</p>
</section>
</article>
Here:
- The <article> element specifies independent, self-contained content.
- The <section> element defines sections in a document, such as chapters, headers, footers, or any other sections of the document.
