就在已有的页面用js动态插入一段html代码，不改变其它原有标签的属性

我要固定浮动在底部

//只靠这段代码，改变style

该如何实现？

<div style="left:0; bottom:0; POSITION:absolute; width:100px; height:100px; z-index:100;">我要固定浮动在底部</div>

到底要底部哪个位置，自己改下left:***

#foot{position:fixed;_position:absolute;bottom:0px;_bottom:0px;_margin-top:expression(this.style.pixelHeight+document.documentElement.scrollTop)}

试下。

我的意思是随便找个页面，粘贴上这段代码，这个div就可以固定浮动在页面最低端，
拖动滚动条浏览始终在最低端
