前段时间一直在忙微课比赛的事情，博客更新比较少，抱歉，今天抽空一更。

## 1.简介 ##

前面我们曾经用两篇文章《[纯CSS3文字效果推荐][CSS3]》、《[CSS3立体文字最佳实践][CSS3 1]》给大家介绍过利用CSS3 text-shaodwo实现阴影文字、立体文字效果，但是纯css3实现的方式也有局限性，比如大量应用时会延缓页面加载速度，效果的可控制性不强，今天给大家推荐一个js插件来弥补这些缺失，隆重推出[SHINE.js][]。

大家可以看看这篇文章《[Better than Pure CSS3][]》学学使用方法，也可以到[官方网站][SHINE.js]具体学习。

## 2.使用步骤 ##

### a. 引入插件 ###

### b. 实例化shine.js ###

//默认参数实例化，my-shine-object为需要添加阴影的元素
    var shine = new Shine(document.getElementById('my-shine-object'));

我们也可以先设置参数，然后实例化对象

var shine_config = new shinejs.Config({
    	numSteps: 10,
    	offset = 0.25,
    	blur: 100,
    	opacity: 0.5,
     shadowRGB: new shinejs.Color(255, 0, 0)
    });
    var shine = new Shine(document.getElementById("my-shine-object"), shine_config);

### c. 阴影的相关操作 ###

我们可以设置阴影的鼠标移动响应

window.addEventListener('mousemove', function(event) {
      shine.light.position.x = event.clientX;
      shine.light.position.y = event.clientY;
      shine.draw();
    }, false);

## 3.API详解 ##

API详解请大家参考官方 [github主页][SHINE.js]。

### a.构造方法 ###

Shine(domElement, optConfig, optClassPrefix, optShadowProperty)
