a img{
filter: Alpha(Opacity=50, FinishOpacity=50, Style=50, StartX=50, StartY=50, FinishX=50, FinishY=50);
border:0px;
}
a img:hover{
filter: Alpha(Opacity=100, FinishOpacity=100, Style=100, StartX=100, StartY=100, FinishX=100, FinishY=100);
border:0px;

border:#CCCCCC solid 1px;
border-bottom:2px #999999 solid;
border-right:2px #999999 solid;

Answer 1

伪类不是这么写的~a img{
filter: Alpha(Opacity=50, FinishOpacity=50, Style=50, StartX=50, StartY=50, FinishX=50, FinishY=50);
border:0px;
}
a:hover img{
filter: Alpha(Opacity=100, FinishOpacity=100, Style=100, StartX=100, StartY=100, FinishX=100, FinishY=100);
border:0px;
}
a:visted img{
filter: Alpha(Opacity=50, FinishOpacity=50, Style=50, StartX=50, StartY=50, FinishX=50, FinishY=50);
border:#CCCCCC solid 1px;
border-bottom:2px #999999 solid;
border-right:2px #999999 solid;
}

Answer 2

class="ico" 这个没有定义

Answer 3

建议把 a img 直接改为 .ico
