Step 1: HTML – Creating the Navigation Bar Structure
We’ll start by setting up the HTML structure for the navigation menu.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Lava Lamp Navigation Bar</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<div class="nav">
<div class="lamp"></div>
<a href="#" onmouseover="moveLamp(this)">Home</a>
<a href="#" onmouseover="moveLamp(this)">About</a>
<a href="#" onmouseover="moveLamp(this)">Services</a>
<a href="#" onmouseover="moveLamp(this)">Contact</a>
</div>
<script src="script.js"></script>
</body>
</html>
Step 2: CSS – Styling the Navigation Bar & Lava Lamp Effect
The CSS styles will create a modern, dark-themed navbar with a glowing hover effect that follows the mouse.
body {
margin: 0;
font-family: Arial, sans-serif;
display: flex;
justify-content: center;
align-items: center;
height: 100vh;
background: #222;
}
.nav {
position: relative;
display: flex;
background: #333;
padding: 10px;
border-radius: 50px;
}
.nav a {
position: relative;
color: white;
text-decoration: none;
padding: 15px 30px;
font-size: 18px;
z-index: 2;
}
.nav .lamp {
position: absolute;
width: 80px;
height: 40px;
background: linear-gradient(45deg, #ff416c, #ff4b2b);
border-radius: 20px;
transition: 0.4s;
top: 10px;
left: 15px;
z-index: 1;
}
Step 3: JavaScript – Making the Lava Lamp Move on Hover
Now, we’ll use JavaScript to detect which navigation link the mouse is over and move the lava lamp smoothly.
function moveLamp(element) {
let lamp = document.querySelector(".lamp");
let rect = element.getBoundingClientRect();
let navRect = document.querySelector(".nav").getBoundingClientRect();
lamp.style.left = rect.left - navRect.left + "px";
lamp.style.width = rect.width + "px";
}
How It Works
1️⃣ User hovers over a navigation link (e.g., “Home”, “About”).
2️⃣ The JavaScript function calculates the position of the hovered link.
3️⃣ The lava lamp moves smoothly to match the hovered link.
4️⃣ The CSS gradient effect creates a glowing hover transition.
