悬停时CSS3暗图像

Question

我有 .css 使我的图像在悬停时变暗:

a.darken {
    display: inline-block;
    background: #222222;
    padding: 0;
}

a.darken img {
    display: block;

    -webkit-transition: all 0.5s linear;
       -moz-transition: all 0.5s linear;
        -ms-transition: all 0.5s linear;
         -o-transition: all 0.5s linear;
            transition: all 0.5s linear;
}

a.darken:hover img {
    opacity: 0.1;

}

我想知道我怎么能改变它在正常状态下变暗并且在悬停时正常​​？

Answer 1

将 opacity: 0.1 移动到正常状态并在悬停时将其恢复为 1.0:

a.darken img {
    display: block;
    opacity: 0.1;

    -webkit-transition: all 0.5s linear;
       -moz-transition: all 0.5s linear;
        -ms-transition: all 0.5s linear;
         -o-transition: all 0.5s linear;
            transition: all 0.5s linear;
}

a.darken:hover img {
    opacity: 1.0;
}
