伪元素前面使用标签，用标签选择就只生效阴影，旋转和缩放是不生效的，用伪类就可以生效


<style>

        img{
            display: inline-block;
            position: absolute;

            box-shadow: 0 0 10px rgba(0, 0, 0, .5);
        }
        .img:hover{
            transform: rotateZ(0deg) scale(1.3);
            z-index: 1;
            box-shadow: none;

        }

他这个使用img选择伪元素时，只有那个transform不生效，但是用伪类选择就可以生效

这里吗？有生效的啊

img

transform属性不能同时写scale和rotate吧！你试下用一个属性看下有没有生效
