必须在单个过滤器调用中形成要应用的过滤器。设置如下:
progid : DXImageTransform.Microsoft.BasicImage(grayscale = 1)
CSS的工作方式如下:
.demo { background: transparent; -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr = #00FFFFFF,endColorstr = #00FFFFFF) progid:DXImageTransform.Microsoft.BasicImage(grayscale = 1)"; /* IE8 */ zoom: 1; }
