css:
（1）即使是旋转，也仍然要在html中设置perspective: xpx;否则无法看出视距
（2）设置rotateZ也是通过 transform: rotateZ(具体数值)；，可以同时设置多个rotateY或者Z
（3）backface-visibility;是用来设置图片的的可见性，默认值为可见

html {
    perspective: 800px;
}

body {
    border: 1px solid red;
}

.box1 {
    width: 366px;
    height: 240px;
    background-image: url('../img/QQ截图20210209193307.png');
    margin: 100px auto;
    transition: 2s;
}

body:hover .box1 {
    transform: rotateZ(1turn) rotateX(1turn);
    /* 设置背面的可见性，一般默认值是可见 */
    backface-visibility: hidden;
}
