Question

下午好！有必要使用doesnotexist在Opera 12的手写笔黑客上书写：-o-prefocus，.selector

有这样的代码：

.class-name 
    background url('my.svg') no-repeat
    background-size contain

    .svg_no &
       &.icon_size
            &_16
                background url('my_size_16.png') no-repeat
            &_32
                background url('my_size_32.png') no-repeat
            &_56
                background url('my_size_56.png') no-repeat

现在位于：

.class-name {
  background: url("my.svg") no-repeat;
  background-size: contain;
}
.svg_no .class-name.icon_size_16 {
   background: url("my_size_16.png") no-repeat;
}
.svg_no .class-name.icon_size_32 {
   background: url("my_size_32.png") no-repeat;
}
.svg_no .class-name.icon_size_56 {
  background: url("my_size_56.png") no-repeat;
}

如何添加以下行：“donotexist：-o-prefocus，.selector”：

.class-name {
  background: url("my.svg") no-repeat;
  background-size: contain;
}
doesnotexist:-o-prefocus, .class-name.icon_size_16,
.svg_no .class-name.icon_size_16 {
   background: url("my_size_16.png") no-repeat;
}
doesnotexist:-o-prefocus, .class-name.icon_size_32,
.svg_no .class-name.icon_size_32 {
   background: url("my_size_32.png") no-repeat;
}
doesnotexist:-o-prefocus, .class-name.icon_size_56,
.svg_no .class-name.icon_size_56 {
    background: url("my_size_56.png") no-repeat;
}

试试这个：

.class-name
    background url('my.svg') no-repeat
    background-size contain

    &.icon_size
        &_16
            /doesnotexist:-o-prefocus
            &
            .svg_no &
                background url('my_size_16.png') no-repeat
        &_32
            /doesnotexist:-o-prefocus
            &
            .svg_no &
                background url('my_size_32.png') no-repeat
        &_56
            /doesnotexist:-o-prefocus
            &
            .svg_no &
                background url('my_size_56.png') no-repeat

如何在手写笔上为Opera 12编写一个hack？
