分析错误与不透明度

Question

当我做grunt（我用凹编译以下）我买了含有的Progid线分析器错误我得到这个http://pastebin.com/thfyTJ0K

.opacity0 { 
display:block !important; 

-moz-transition:all 500ms ease 0s; 
-o-transition:all 500ms ease 0s; 
-webkit-transition:all 500ms ease 0s; 
transition:all 500ms ease 0s; 

-moz-opacity: 0; 
-khtml-opacity: 0; 
opacity: 0; 
-ms-filter: ~"progid:DXImageTransform.Microsoft.Alpha(Opacity=0)"; 
filter: ~progid:DXImageTransform.Microsoft.Alpha(opacity=0); 
filter:alpha(opacity=0); 
} 

.opacity50 { 
display:block !important; 

-moz-transition:all 500ms ease 0s; 
-o-transition:all 500ms ease 0s; 
-webkit-transition:all 500ms ease 0s; 
transition:all 500ms ease 0s; 

-moz-opacity: 0.5; 
-khtml-opacity: 0.5; 
opacity: 0.5; 
-ms-filter: ~"progid:DXImageTransform.Microsoft.Alpha(Opacity=0.5)"; 
filter: ~progid:DXImageTransform.Microsoft.Alpha(opacity=0.5); 
filter:alpha(opacity=0.5); 
} 

.opacity1 { 
display:block !important; 

-moz-transition:all 500ms ease 0s; 
-o-transition:all 500ms ease 0s; 
-webkit-transition:all 500ms ease 0s; 
transition:all 500ms ease 0s; 

-moz-opacity: 1; 
-khtml-opacity: 1; 
opacity: 1; 
-ms-filter:~"progid:DXImageTransform.Microsoft.Alpha(Opacity=100)"; 
filter: ~progid:DXImageTransform.Microsoft.Alpha(opacity=100); 
filter:alpha(opacity=1);  
} 

。我试图把~这些线路，但没有奏效

Answer 1

.opacity50 { 
    -ms-filter: ~"progid:DXImageTransform.Microsoft.Alpha(opacity=50)"; 
    filter: ~"progid:DXImageTransform.Microsoft.Alpha(opacity=50)"; 
} 

另外：使用而不是(opacity=50)(opacity=.5)
