HTML <nav> Tag

The HTML <nav> tag is a semantic element that defines a section of a webpage that contains navigation links. It is used to group together links for easy navigation, making it easier for both users and search engines to understand the structure of a website. The <nav> tag is often used to create menus, lists of links, or any other type of navigational content, helping users move through different sections or pages of a site.

Syntax of the <nav> Tag

html
<nav>
    <!-- Navigation links go here -->
</nav>

The <nav> tag is used to wrap a block of links that lead to different sections of the website or external resources. This tag provides context and meaning to the enclosed links, making it easier for assistive technologies and search engines to interpret the purpose of these links.

Attributes of the <nav> Tag

The <nav> tag does not have any specific attributes of its own but supports global attributes. Some of these commonly used attributes include:

  • id: Assigns a unique identifier to the navigation section, which can be useful for styling or scripting.
  • class: Adds a class name that can be used for CSS styling or JavaScript manipulation.
  • style: Defines inline styles for the navigation section.
  • aria-label: Improves accessibility by providing a descriptive label for screen readers, especially for multiple <nav> sections on the same page.

Example of aria-label usage:

html
<nav aria-label="Main navigation">
    <!-- Navigation links -->
</nav>

Examples of HTML <nav> Tag

Example 1: Basic Navigation Bar

html
<!DOCTYPE html>
<html>
<head>
    <title>Basic Navigation Bar</title>
</head>
<body>
    <nav>
        <ul>
            <li><a href="index.html">Home</a></li>
            <li><a href="about.html">About Us</a></li>
            <li><a href="services.html">Services</a></li>
            <li><a href="contact.html">Contact</a></li>
        </ul>
    </nav>
</body>
</html>

In this example, the <nav> tag contains a simple navigation bar with links to different sections of the website.

Example 2: Multiple Navigation Sections with aria-label.

html
<!DOCTYPE html>
<html>
<head>
    <title>Multiple Navigation Bars</title>
</head>
<body>
    <header>
        <nav aria-label="Main navigation">
            <a href="index.html">Home</a> | 
            <a href="about.html">About Us</a> | 
            <a href="contact.html">Contact</a>
        </nav>
    </header>
    <aside>
        <nav aria-label="Sidebar navigation">
            <ul>
                <li><a href="blog.html">Blog</a></li>
                <li><a href="careers.html">Careers</a></li>
                <li><a href="privacy.html">Privacy Policy</a></li>
            </ul>
        </nav>
    </aside>
</body>
</html>

This example shows the use of multiple <nav> elements, each with an aria-label attribute to enhance accessibility by describing the purpose of each navigation section.
