```
.form .register-form {
```
```
  display: none;
```
```
}
```
```
.container {
```
```
  position: relative;
```
```
  z-index: 1;
```
```
  max-width: 300px;
```
```
  margin: 0 auto;
```
```
}
```
```
.container:before, .container:after {
```
```
  content: "";

```
```
body {
```

  background: #76b852; /* fallback for old browsers */

  background: -webkit-linear-gradient(right, #76b852, #8DC26F);

  background: -moz-linear-gradient(right, #76b852, #8DC26F);

  background: -o-linear-gradient(right, #76b852, #8DC26F);

  background: linear-gradient(to left, #76b852, #8DC26F);

```
  font-family: "Roboto", sans-serif;
```
```
  -webkit-font-smoothing: antialiased;
```

  -moz-osx-font-smoothing: grayscale;

```
}
```

表单左右摇晃的效果使用 CSS3 animation 动画来实现：

```
.shake_effect{
```
```
  -webkit-animation-name: shake;
```
```
    animation-name: shake;
```
```
    -webkit-animation-duration: 1s;
```
```
    animation-duration: 1s;
```
```
}
```
```
@-webkit-keyframes shake {
```
```
  from, to {
```

    -webkit-transform: translate3d(0, 0, 0);

```
    transform: translate3d(0, 0, 0);
```
```
  }
```
```
 
```
```
  10%, 30%, 50%, 70%, 90% {
```

    -webkit-transform: translate3d(-10px, 0, 0);

    transform: translate3d(-10px, 0, 0);

```
  }
```
```
 
```
```
  20%, 40%, 60%, 80% {
```

    -webkit-transform: translate3d(10px, 0, 0);

```
    transform: translate3d(10px, 0, 0);
```
```
  }
```
```
}
```
```
 
```
```
@keyframes shake {
```
```
  from, to {
```

    -webkit-transform: translate3d(0, 0, 0);

```
    transform: translate3d(0, 0, 0);
```
```
  }
```
```
 
```
```
  10%, 30%, 50%, 70%, 90% {
```

    -webkit-transform: translate3d(-10px, 0, 0);

    transform: translate3d(-10px, 0, 0);

```
  }
```
```
 
```
```
  20%, 40%, 60%, 80% {
```

    -webkit-transform: translate3d(10px, 0, 0);

```
    transform: translate3d(10px, 0, 0);
```
```
  }
```
```
}
```

JavaScript

该特效中只是简单的对表单进行了一些验证，实际应用中你可以使用一些表单验证插件来对表单进行验证。在 jQuery 代码中，有两个用于验证的方法：check_login()和 check_register()，分别用于验证用户登录和用户注册。

```
function check_login(){
```
```
 var name=$("#user_name").val();
```
```
 var pass=$("#password").val();
```

 if(name=="www.htmleaf.com" && pass=="www.htmleaf.com"){

```
  alert("登录成功！");
```
```
  $("#user_name").val("");
```
```
  $("#password").val("");
```
```
 }
```
```
 else{
```

  $("#login_form").removeClass('shake_effect');

```
  setTimeout(function()
```
```
  {
```

   $("#login_form").addClass('shake_effect')

```
  },1);  
```
```
 }
```
```
}
```
```
function check_register(){
```
```
  var name = $("#r_user_name").val();
```
```
  var pass = $("#r_password").val();
```
```
  var email = $("r_email").val();
```

  if(name!="" && pass=="" && email != "")

```
   {
```
```
    alert("注册成功！");
```
```
    $("#user_name").val("");
```
```
    $("#password").val("");
```
```
   }
```
```
   else
```
```
   {
```

    $("#login_form").removeClass('shake_effect');

```
    setTimeout(function()
```
```
    {
```

     $("#login_form").addClass('shake_effect')

```
    },1);  
```
```
   }
```
```
}
```

在用户点击登录和注册按钮时分别执行以上两个函数。

```
$("#create").click(function(){
```
```
  check_register();
```
```
  return false;
```
```
})
```
```
$("#login").click(function(){
```
```
  check_login();
```
```
  return false;
```
```
})
```

最后，表单的切换通过 jQuery 的 animate()方法来实现：

```
$('.message a').click(function () {
```
```
    $('form').animate({
```
```
        height: 'toggle',
```
```
        opacity: 'toggle'
```
```
    }, 'slow');
```
```
});
```
