为了简化示例，我们将创建一个简单的登录表单的CSS样式。以下是一个基本的HTML和CSS代码示例：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Login Page</title>
<style>
body {
font-family: Arial, sans-serif;
background-color: #f4f4f4;
padding: 20px;
}
.login-container {
background-color: #fff;
padding: 20px;
border-radius: 5px;
box-shadow: 0 2px 5px rgba(0, 0, 0, 0.2);
max-width: 300px;
margin: 100px auto;
}
input[type="text"], input[type="password"] {
width: 100%;
padding: 10px;
margin: 10px 0;
border: 1px solid #ccc;
border-radius: 4px;
}
input[type="submit"] {
width: 100%;
padding: 10px;
background-color: #007bff;
color: white;
border: none;
border-radius: 4px;
cursor: pointer;
font-size: 16px;
}
input[type="submit"]:hover {
background-color: #0056b3;
}
.forgot-password {
text-align: right;
font-size: 14px;
}
</style>
</head>
<body>
<div class="login-container">
<form action="/submit-your-login-form" method="post">
<h2>Login</h2>
<div>
<input type="text" placeholder="Username" name="username" required>
</div>
<div>
<input type="password" placeholder="Password" name="password" required>
</div>
<div class="forgot-password">
<a href="/forgot-password">Forgot password?</a>
</div>
<div>
<input type="submit" value="Login">
</div>
</form>
</div>
</body>
</html>这个简单的HTML和CSS样式将创建一个有基本布局、颜色、边框和阴影的登录表单。用户可以根据自己的需求进一步美化这个登录页面。
