帮我用css和js做一个拟态滑动登录注册页面

好的，以下是一个简单的拟态滑动登录注册页面的样式和代码：

HTML代码：

<div class="container">
  <div class="form-container sign-up-container">
    <form action="#">
      <h1>Create Account</h1>
      <input type="text" placeholder="Name" />
      <input type="email" placeholder="Email" />
      <input type="password" placeholder="Password" />
      <button>Sign Up</button>
    </form>
  </div>
  <div class="form-container sign-in-container">
    <form action="#">
      <h1>Sign in</h1>
      <input type="email" placeholder="Email" />
      <input type="password" placeholder="Password" />
      <a href="#">Forgot your password?</a>
      <button>Sign In</button>
    </form>
  </div>
  <div class="overlay-container">
    <div class="overlay">
      <div class="overlay-panel overlay-left">
        <h1>Welcome Back!</h1>
        <p>To keep connected with us please login with your personal info</p>
        <button class="ghost" id="signIn">Sign In</button>
      </div>
      <div class="overlay-panel overlay-right">
        <h1>Hello, Friend!</h1>
        <p>Enter your personal details and start journey with us</p>
        <button class="ghost" id="signUp">Sign Up</button>
      </div>
    </div>
  </div>
</div>

  font-weight: 500;
  cursor: pointer;
  transition: all 0.3s ease-in-out;
}

form button:hover {
  background-color: #fff;

form button.ghost {
  background-color: transparent;
  border-color: #fff;

form a {

form a:hover {
  text-decoration: underline;
}

.overlay-right .ghost {
  background-color: #fff;
  border-color: #fff;
  color: #FF4B2B;
}

.overlay-right .ghost:hover {
  background-color: #FF4B2B;
  color: #fff;
}

.overlay-right button {
  background-color: transparent;
  border-color: #fff;
  color: #fff;
}

.overlay-right button:hover {
  background-color: #fff;
  color: #FF4B2B;
  border-color: #fff;
}

JavaScript代码：

const signUpButton = document.getElementById('signUp');
const signInButton = document.getElementById('signIn');
const container = document.getElementById('container');

signUpButton.addEventListener('click', () => {
  container.classList.add('right-panel-active');
});

signInButton.addEventListener('click', () => {
  container.classList.remove('right-panel-active');
});

以上代码实现了一个拟态滑动登录注册页面，其中包括两个表单（登录和注册），以及一个覆盖整个页面的背景和两个覆盖表单的覆盖层。通过点击“Sign Up”或“Sign In”按钮，可以在两个表单之间进行切换，同时覆盖层和背景也会相应地滑动切换。您可以根据需要进行修改和优化。
