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{

</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>以上就是一款带有发光动画的HTML5表单的内容，更多相关内容请关注PHP中文网（www.php.cn）！
