一款带有发光动画的HTML5表单

今天给大家秀一款带有发光动画的HTML5表单，挺酷的，效果图如下：

  当表单获取焦点时，表单四周就会呈现出发光动画的效果，并不断地进行颜色渐变；当表单失去焦点时，停止发光。其中颜色渐变的动画只有基于webkit的浏览器才有效果，比如chrome和safari。下面简单贴一下实现这个发光HTML5表单的CSS代码和HTML代码，如果你喜欢可以将它分享给你的朋友。

HTML代码如下：

<div class="rain">
    <div class="border start">
        <form>
            <label for="email">Email</label>
            <input name="email" type="text" placeholder="Email"/>
            <label for="pass">Password</label>
            <input name="pass" type="password" 
placeholder="Password"/>
                        <input type="submit" value="LOG IN"/>
        </form>
    </div>
</div>

CSS代码如下：

<style>
    body{
        background: #000;
        color: #DDD;
        font-family: 'Helvetica', 'Lucida Grande', 'Arial', sans-serif;
    }
    .border,
    .rain{
        height: 170px;
        width: 320px;
    }
    /* Layout with mask */
    .rain{
         padding: 10px 12px 12px 10px;

        filter: progid:DXImageTransform.Microsoft.gradient(

        -moz-box-shadow: 0px 1px 1px #000, 0px 1px 0px rgba(255,255,255,.3)

        -webkit-box-shadow: 0px 1px 1px #000, 0px 1px 0px

        text-shadow: 0 1px 1px #000;
        outline: none;
        width:80px;
    }
</style>

其中，表单焦点切换需要jquery支持，js代码如下：

<script 
src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
<script>
    $(function(){
      var $form_inputs =   $('form input');
      var $rainbow_and_border = $('.rain, .border');
      /* Used to provide loping animations in fallback mode */
      $form_inputs.bind('focus', function(){
        $rainbow_and_border.addClass('end').removeClass('unfocus 
start');
      });
      $form_inputs.bind('blur', function(){
        $rainbow_and_border.addClass('unfocus 
start').removeClass('end');
      });
      $form_inputs.first().delay(800).queue(function() {
        $(this).focus();
      });
    });
</script>
