Introduction to the <nav> Element
The <nav> element in HTML is used to define a block of navigation links, typically displayed as a menu on a webpage. This element is crucial for helping users navigate through the website and find the content they are looking for.
Basic Usage of the <nav> Element
The <nav> element can contain lists of links that lead to different sections of the site or to other websites. It's a semantic element, meaning it specifically indicates that the content within it is a navigation section.
Example: Creating a Simple Navigation Bar
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Sample Navigation</title>
</head>
<body>
<header>
<h1>My Website</h1>
<nav>
<ul>
<li><a href="#home">Home</a></li>
<li><a href="#about">About</a></li>
<li><a href="#services">Services</a></li>
<li><a href="#contact">Contact</a></li>
</ul>
</nav>
</header>
</body>
</html>
In this example, the <nav> element is used to enclose an unordered list of links that make up the navigation bar. This structure is common and helps ensure that the navigation is easily recognizable and accessible.
Fun Question
Why do you think the element is named "nav"? Imagine if you had to name it—what would you call it? How would that name reflect its purpose?
