Pros and Cons of a Glassmorphism Login Form
Before diving into the code, it is important to understand the advantages and limitations of using a Glassmorphism Login Form in your UI/UX workflow.
Pros
- Modern Aesthetic: Gives your website a high-end, premium, and futuristic feel that stands out from flat designs.
- Visual Hierarchy: The blur effect helps create a clear sense of depth, making the login container pop against vibrant backgrounds.
- Versatility: Works beautifully with colorful, animated, or gradient backgrounds.
- Lightweight: Achieving this look requires very little code and no heavy image assets.
Cons
- Browser Compatibility: Older browsers (like Internet Explorer) do not support the
backdrop-filterproperty. - Accessibility Risks: If not implemented carefully, the transparency can make text difficult to read for users with visual impairments.
- Performance: Applying heavy blur effects on very large areas can sometimes cause lag on low-end mobile devices.

Why Use a Glassmorphism Login Form?
This login form features:
- A dark gradient background with colorful floating blurred blobs for depth.
- A glass-like container with backdrop-filter blur and subtle borders.
- Smooth inputs with rounded corners and high-contrast placeholder text.
- A functional “show password” toggle using an SVG eye icon.
It’s lightweight, requires no external libraries, and works perfectly on desktop and mobile devices.

Step 1: Building the Glassmorphism Login Form HTML
First, we create the basic HTML skeleton. We use a full-screen section with floating color blobs for the background effect, followed by the main glass container.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Glassmorphism Login Form</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<section>
<!-- Floating background blobs -->

<div class="inputBox">

<!-- Eye icon for toggle -->
<div class="eye-icon" onclick="togglePassword()">
<svg width="20px" height="20px" viewBox="0 0 24 24" fill="none" xmlns="[http://www.w3.org/2000/svg](http://www.w3.org/2000/svg)">

<script src="script.js"></script>

<div id=”step-2″></div>
Step 2: Adding the Glass Effect with CSS
The magic of the Glassmorphism Login Form happens in the CSS. We utilize the backdrop-filter property to create that blurred glass aesthetic.
* {
margin: 0;
padding: 0;
box-sizing: border-box;
font-family: 'Segoe UI', Tahoma, Geneva, Verdana, sans-serif;
}
body {
overflow: hidden;
}
section {
display: flex;
justify-content: center;
align-items: center;
min-height: 100vh;
background: linear-gradient(to bottom, #0f0c29, #302b63, #24243e);
}
/* Floating Background Blobs */
section .color {
position: absolute;
filter: blur(150px);
}
section .color:nth-child(1) {
top: -350px;
width: 600px;
height: 600px;
background: #ff359b;
}
section .color:nth-child(2) {
bottom: -150px;
left: 100px;
width: 500px;
height: 500px;
background: #fffd87;
}
section .color:nth-child(3) {
bottom: 50px;
right: 100px;
width: 300px;
height: 300px;
background: #00d2ff;
}
/* Glassmorphism Container */
.container {
position: relative;
width: 400px;
min-height: 400px;
background: rgba(255, 255, 255, 0.1);
border-radius: 10px;
display: flex;
justify-content: center;
align-items: center;
backdrop-filter: blur(10px);
border: 1px solid rgba(255, 255, 255, 0.5);
border-right: 1px solid rgba(255, 255, 255, 0.2);
border-bottom: 1px solid rgba(255, 255, 255, 0.2);
box-shadow: 0 25px 45px rgba(0, 0, 0, 0.2);
}
/* ...rest of the styling remains the same ... */
<div id=”step-3″></div>
Step 3: Password Toggle JavaScript
To make our Glassmorphism Login Form more user-friendly, we add a simple JavaScript function to toggle password visibility. This improves user experience significantly.
function togglePassword() {
const passwordInput = document.getElementById('password');
if (passwordInput.type === 'password') {
passwordInput.type = 'text';
} else {
passwordInput.type = 'password';
}
}<div id=”customization”></div>
Customization and SEO Tips
To further improve your project, consider these tips:
- Colors: Modify the floating blob colors to match your brand.
- Accessibility: Ensure your contrast ratios are high enough for all users to read.
- Performance: Check the MDN documentation for browser compatibility regarding
backdrop-filter.
This design is elegant, modern, and easy to implement. Feel free to use this code in your upcoming projects. If you found this Glassmorphism Login Form tutorial helpful, check out our other guides on [Modern Web Design] or [JavaScript UI Projects].
