兼容 IE6 的遮罩层,利用“* Html”这个 Hack,设置 IE6 使用 position
;和 expression 来模拟 fixed 的效果,另外设置 background(*)防止抖动。.overlay { position: fixed; z-index: 100000; /*按需设置*/ width: 100%; height: 100%; top: 0; left: 0; filter: alpha(opacity=50); opacity: 0.5; overflow: hidden; background-color: #000; } * html { background: url(*) fixed; } * html body { margin: 0; height: 100%; } * html .overlay { position: absolute; left: expression( documentElement.scrollLeft + documentElement.clientWidth - this.offsetWidth ); top: expression( documentElement.scrollTop + documentElement.clientHeight - this.offsetHeight ); }
