<ul>
<li id="a" class="a"><p>使用方法:</p>
		   <p>1,导入jquery和setwaterfall插件,可直接查看源代码script id="setwaterfall"为该插件,或者点击<a href="setwaterfall.js">setwaterfall.js</a></p>
		   <p>2,如$("li").setwaterfall(),li为要瀑布流化的元素</p>
		   <p>3,设置相应的css,要求父层定位为position:relative;瀑布流的元素定位为position:absolute</p>
		   <p>4,根据需要设置宽和高,padding和mairgin</p>
		   <p>ps:简陋版本,仅供参考</p>
