Hello guys in this tutorial we will create advanced animated submenu using HTML CSS & JavaScript
First we need to create two files index.html and style.css then we need to do code for it.
Step:1
Add below code inside index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>Animated Submenu</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta https-equiv="X-UA-Compatible" content="ie=edge" />
<link rel="stylesheet" href="style.css" />
<link href="https://fonts.googleapis.com/css2?family=IBM+Plex+Sans&display=swap" rel="stylesheet">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
</head>
<body>
<header>
<div class="container">
<div class="highlighter"style=""></div>
<nav class="nav">
<ul class="nav_menu">
<li class="nav_item"><a href="#" class="nav_link nav_active-link">Home</a></li>
<li class="nav_item">
<a href="#" class="nav_link">About</a>
<ul class="nav_submenu">
<li class="nav_submenu-item"><a href="#" class="nav_submenu-link">Who We Are</a></li>
<li class="nav_submenu-item"><a href="#" class="nav_submenu-link">Training</a></li>
</ul>
</li>
<li class="nav_item">
<a href="#" class="nav_link">Services</a>
<ul class="nav_submenu">
<li class="nav_submenu-item"><a href="#" class="nav_submenu-link">Service 01</a></li>
<li class="nav_submenu-item"><a href="#" class="nav_submenu-link">Service 02</a></li>
<li class="nav_submenu-item"><a href="#" class="nav_submenu-link">Service 03</a></li>
<li class="nav_submenu-item"><a href="#" class="nav_submenu-link">Service 04</a></li>
</ul>
</li>
<li class="nav_item nav_item--team">
<a href="#" class="nav_link">Career</a>
<div class="nav_submenu">
<p class="paragraph">
Lorem ipsum dolor sit amet consectetur, adipisicing elit.
Illo, quas is iste magnam,
vitae recusandae quaerat inventore repudiandae.
</p>
</div>
</li>
</ul>
</nav>
</div>
</header>
<script>
const highlighter = document.querySelector('.highlighter');
const navItems = document.querySelectorAll('.nav_item');
navItems.forEach((cur, index) => {
cur.addEventListener('mouseenter', handleEnter);
cur.addEventListener('mouseleave', handleLeave);
});
function handleEnter() {
var subMenuCords = this.querySelector('.nav_submenu').getBoundingClientRect();
highlighter.classList.add('open');
var allCords = {
left: subMenuCords.left,
top: subMenuCords.top,
height: subMenuCords.height,
width: subMenuCords.width,
}
highlighter.style.width = `${allCords.width}px`;
highlighter.style.height = `${allCords.height}px`;
highlighter.style.left = `${allCords.left}px`;
highlighter.style.top = `${allCords.top}px`;
}
function handleLeave() {
highlighter.classList.remove('open');
}
</script>
</body>
</html>
