## 1. HTML基础结构
```html

<link rel="stylesheet" href="styles.css">
</head>
<body>
<div class="register-container">
<h2>创建账户</h2>
<form id="registerForm">
<div class="form-group">
<label for="username">用户名</label>
<input type="text" id="username" name="username" required>
<span class="error-message"></span>
</div>
<div class="form-group">
<label for="email">电子邮箱</label>
<input type="email" id="email" name="email" required>

</div>
<div class="form-group">

}
CSRF防护:
<input type="hidden" name="_csrf" value="<!-- 服务器生成token -->">
密码加密:
// 使用crypto-js等库进行前端加密
import sha256 from 'crypto-js/sha256';
const encryptedPassword = sha256(password).toString();
速率限制:
// 提交按钮防抖
let isSubmitting = false;
function handleSubmit() {
if (isSubmitting) return;
isSubmitting = true;
// ...提交逻辑
}
HSTS头部(服务器配置):
Strict-Transport-Security: max-age=31536000; includeSubDomains

完整项目结构:
/register-page
├── index.html
├── styles.css
├── script.js
└── README.md
第三方登录:
<div class="social-login">
<button class="google-login">
<img src="google-icon.png" alt=""> Google登录
</button>
</div>
密码可见切换:
function togglePasswordVisibility(fieldId) {
const field = document.getElementById(fieldId);
field.type = field.type === 'password' ? 'text' : 'password';
}
进度条指示器:
.password-strength {
height: 4px;
background: #eee;
margin-top: 5px;
}
验证码功能:
<div class="form-group">
<label>验证码</label>
<div class="captcha-container">
<input type="text" id="captcha" required>
<img src="/captcha" alt="验证码" class="captcha-img">
</div>
</div>
多步骤注册表单:
// 使用CSS隐藏非当前步骤
document.querySelectorAll('.form-step').forEach((step, index) => {
step.style.display = index === 0 ? 'block' : 'none';
});
通过以上技术组合,您可以构建出: - 符合现代Web标准的响应式注册页面 - 具有完善客户端验证的用户体验 - 包含基本安全防护措施的健壮系统 - 易于扩展的功能基础架构 “`
