The <nav> element defines a block of navigation links, either within the current document or to other documents. Note, that not all links in the HTML document can be placed inside the <nav> element; it can only include major navigation blocks. For example, the <nav> tag cannot be placed in the <footer> tag for defining links in the footer of the website.
Take a look at the example below:
The code:
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<header>
<h1>My First Website</h1>
</header>
<body>
<nav>
<a href=”#”> MENU</a>
<a href=”#”> CONTACT US</a>
<a href=”#”> ABOUT US</a>
</nav>
