项目需求
要求制作上图所看到的的效果，能达到灵活可配的效果。
我想初步想法是用div+css来制作。
------------------------------------------------------------------------------------------------------
模型抽象
以下的这个模型是我抽象出来的一个简单的解决方式。div能够表示一个矩形。然后再加上一个旋转90度的div就能够组起来达到我们想要的效果了。使用div就能够非常方便地对应各种事件。使站点灵活可配。
------------------------------------------------------------------------------------------------------
技术难点
1、怎样做到让div旋转？
假设设置的值为正数表示顺时针旋转，假设设置的值为负数，则表示逆时针旋转
2、怎样设置div的层次关系？
z-index

<script type="text/javascript" src="js/text.js"></script>
</head>

实践效果
总结思考
1、面对复杂的问题。要学会抽象当前的问题。
2、不将就是发现的原动力。
