/距离上边为0/
.sl-fixed-top{
bottom:auto;
top:0;
_bottom:auto;
_top:expression(eval(document.documentElement.scrollTop))
}
/距离底部为0/
.sl-fixed-bottom{
bottom:0;
top:0;
_bottom:auto
_top:expression(eval(document.documentElement.scrollTop+document.documentElement.clientHeight-(parseInt(this.currentStyle.marginTop,10||0)-(parseInt(this.currentStyle.marginBottom,10||0))));
}
/距离左边为0;
.sl-fixed-left{
left:0;
_position:absolute;
right:auto;
_left:expression(eval(document.documentElement.scrollLeft))
}
/对于右边为0/
.sl-fixed-right{
right:0;
left:auto;
_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)i);
}
