恕我直言，纯 CSS 是不可能的.最简单的解决方案是使用 jQuery.

IMHO, it is not possible to do with pure CSS. The easiest solution will be using jQuery.

// css
.actioner{
    -webkit-transform: translate(540px,0px); 
    -moz-transform: translate(540px,0px); 
    -o-transform: translate(540px,0px); 
    -ms-transform: translate(540px,0px);
}

// script
$(function(){
    $('.kitty').one("mouseover", function() {
        $('.kitty').addClass('actioner');
    });
});
