  • 让position:fixed在IE6下可用

    * html,* html body{background-image:url(about:blank);background-attachment:fixed}
    * html .plant_header{position:absolute;left:expression(eval(document.documentElement.scrollLeft));top:expression(eval(document.documentElement.scrollTop))}
    这两句是 什么意思?

     /*让position:fixed在IE6下可用!*/

    .fixed-top/*头部固定*/{position:fixed;bottom:auto;top:0px;}
    .fixed-bottom/*底部固定*/{position:fixed;bottom:0px;top:auto;}
    .fixed-left/*左侧固定*/{position:fixed;right:auto;left:0px;}
    .fixed-right/*右侧固定*/{position:fixed;right:0px;left:auto;}
    /*上面的是除了IE6的主流浏览器通用的方法*/
    *html,*htmlbody/*修正IE6振动bug*/{background-image:url(about:blank);background-attachment:fixed;}
    *html.fixed-top/*IE6头部固定*/{position:absolute;bottom:auto;top:expression(eval(document.documentElement.scrollTop));}
    *html.fixed-right/*IE6右侧固定*/{position:absolute;right:auto;left:expression(eval(document.documentElement.scrollLeft+document.documentElement.clientWidth-this.offsetWidth)-(parseInt(this.currentStyle.marginLeft,10)||0)-(parseInt(this.currentStyle.marginRight,10)||0));}
    *html.fixed-bottom/*IE6底部固定*/{position:absolute;bottom:auto;top:expression(eval(document.documentElement.scrollTop+document.documentElement.clientHeight-this.offsetHeight-(parseInt(this.currentStyle.marginTop,10)||0)-(parseInt(this.currentStyle.marginBottom,10)||0)));}
    *html.fixed-left/*IE6左侧固定*/{position:absolute;right:auto;left:expression(eval(document.documentElement.scrollLeft));}
