好的,我可以为您提供一个简单的登录页面的 HTML 和 CSS 代码示例,如下所示:
HTML 代码:
```
<!DOCTYPE html>
<html>
<head>
<title>Login Page</title>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
<div class="login-box">
<h2>Login</h2>
<form>
<div class="user-box">
<input type="text" name="username" required="">
<label>Username</label>
</div>
<div class="user-box">
<input type="password" name="password" required="">
<label>Password</label>
</div>
<a href="#">
<span></span>
<span></span>
<span></span>
<span></span>
<input type="submit" value="Login">
</a>
</form>
</div>
</body>
</html>
```

```
