Create A Glassmorphism Login Form in HTML and CSS

Web Development CSS HTML

This article will show you how to design a glassmorphism login form using HTML and CSS. Glassmorphism is a popular UI design trend based on frosted glass effects, which make elements look translucent with a blurred background.

What is Glassmorphism?

Glassmorphism is a UI design style that gives an element a frosted-glass effect with the following characteristics

Blurred Background: Creates a glassy, frosted effect.
Transparency: Allows part of the background to show through.
Light Borders and Shadows: Adds depth and defines the shape.

Key CSS Properties for Glassmorphism

.glass-effect {
    background: rgba(255, 255, 255, 0.1);
    backdrop-filter: blur(15px);
    border: 1px solid rgba(255, 255, 255, 0.2);
    border-radius: 15px;
    box-shadow: 0 8px 32px rgba(0, 0, 0, 0.4);
}

Creating the HTML Structure

We start by building the structure of the login form. The container holds the username and password input fields along with a submit button

<!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>
</head>
<body>
    <div class="glass-container">
        <h2>Login</h2>
        <form>
            <input type="text" class="input-field" placeholder="Username" required>
            <input type="password" class="input-field" placeholder="Password" required>
            <button type="submit" class="btn">Login</button>
        </form>
    </div>
</body>
</html>

Complete Glassmorphism Login Form

Here's the complete implementation with all the glassmorphism styling

<!DOCTYPE html>

            overflow: hidden;
        }

        body::before {
