最佳回答

检查在您的浏览器中没有残疾(大约17人可以残疾)。

另一种想法是,你的形象只有一次:

background: url(yourimage.png) no-repeat;

之后,它只改变与社会保障局的关系,而没有再次纳入形象:

background-position: 0px 100px;

我猜测你正试图这样做,我只是建议不要把每个阶层的形象包括在内,只改变立场。

问题回答

RynoRn是正确的,但我认为他的回答需要扩大,以适应特别安全局,而不仅仅是特别安全局。

为了使用<代码>compass和scs加以确定,我从问题改为:

混血现在没有提及图像,只是改变了立场:

@mixin verticalHoverSprite($row){
    @include sprite-position(1, $row);
    &:hover{
        @include sprite-position(2, $row);
    }
}

and we add the background image to the socialMediaLink class:

.socialMediaLink{

    @include sprite-background("/assets/icons/socialMediaSprite.png");

    @include verticalHoverSprite(1);

    &.facebook{
            @include verticalHoverSprite(2);
    }
    &.twitter{
            @include verticalHoverSprite(3);
    }
}
