Creating an animated login page in HTML can be achieved using a combination of HTML, CSS, and a bit of JavaScript for enhanced interactivity. Below is an example of a simple animated login page.
HTML
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Animated Login Page</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<div class="login-container">
<div class="login-box">
<h2>Login</h2>
<form>
<div class="input-group">
<input type="text" required>
<label>Username</label>
</div>
<div class="input-group">
<input type="password" required>
<label>Password</label>
</div>
<button type="submit">Login</button>
</form>
</div>
</div>
</body>
</html>

CSS (style.css)

border-radius: 5px;
cursor: pointer;
transition: background 0.3s;
}
button:hover {

}
@keyframes fadeIn {

Explanation
HTML:
- Defines the structure of the login page with a form that includes input fields for the username and password.
- The
labelelements are positioned over the input fields and move up when the input is focused or contains a value.
CSS:
- Styles the body to center the login box and applies a gradient background.
- Adds styles for the login box, including padding, border-radius, and a box-shadow for a card-like effect.
- Animates the login box on page load with a fade-in effect.
- Styles the input fields and labels to create a floating label effect.
- Styles the submit button with a hover effect for visual feedback.
This example creates a visually appealing and interactive login form with simple animations. You can further customize it by adding more styles or JavaScript for additional functionality.
