Prerequisites
Basic knowledge of HTML is required. No other prerequisites are needed.
Step-by-Step Guide
Semantic HTML
Semantic HTML is the use of HTML markup to reinforce the semantics or meaning of the content. For example, <p> for paragraphs, <h1> for main headings, <nav> for navigation links, etc.
Examples
-
<header>: This element represents a container for introductory content or a set of navigational links. -
<nav>: This tag is used to define a set of navigation links. -
<main>: This tag is used to specify the main content of a document. -
<footer>: This tag defines a footer for a document or a section.
Best Practices
- Always use a language attribute in the
<html>tag. - Use heading tags where appropriate (h1 for main title, h2 for subheadings, etc.)
- Use alt attributes for images.
- Use ARIA roles and properties if necessary.
Code Examples
Example 1: Semantic HTML structure
<!DOCTYPE html>
<html lang="en">
<head>
<title>Page Title</title>
</head>
<body>
<header>
<h1>Page Title</h1>
<nav>
<a href="#">Link 1</a> |
<a href="#">Link 2</a> |
<a href="#">Link 3</a>
</nav>
</header>
<main>
<h2>Subheading</h2>
<p>This is some text.</p>
<img src="image.jpg" alt="Description of image">
</main>
<footer>
Copyright information
</footer>
</body>
</html>
This code snippet is a template for a basic webpage with semantic HTML tags. It includes a header with a title and navigation links, a main section with a subheading, some text, and an image with an alt description, and a footer with copyright information.
