1、平面转换-多重转换
多重转换技巧：先平移再旋转

<style>
.box {
width: 800px;
height: 200px;
border: 1px solid #000;
}
img {
width: 200px;
transition: all 5s;
}
/* 鼠标移入box，图片边走边转 */
.box:hover img {
/* 先平移再旋转 */
transform: translate(600px) rotate(360deg);
/* 旋转会改变坐标轴向 */
/* 多重转换：以第一种转换形态的坐标轴为准 */
/* transform: rotate(360deg) translate(600px); */
/* 层叠性 */
/* transform: translate(600px);
transform: rotate(360deg); */
}

2、平面转换-缩放
属性
技巧：
- 通常，只为scale()设置一个值，表示X轴和Y轴等比例缩放
- 取值大于1表示放大，取值小于1表示缩小

<style>
.box {
width: 300px;
height: 210px;
margin: 100px auto;
background-color: pink;
}
.box img {
width: 100%;
transition: all 0.5s;
}
.box:hover img {
/* 修改宽高尺寸，从左上角开始缩放 */
/* width: 500px;
height: 400px; */
/* 大于1，表示放大 */
transform: scale(2);
/* 小于1，表示缩小 */
transform: scale(0.5);
/* 等于1，不变 */
transform: scale(1);
}
</style>

}
.box p {

padding: 10px 10px 0 10px;
}
/* 1. 摆放播放按钮：图片区域的中间 */
.box li {
overflow: hidden;
}
.pic {
position: relative;
}
.pic::after {
position: absolute;
left: 50%;
top: 50%;
/* margin-left: -29px;
margin-top: -29px; */
/* transform: translate(-50%, -50%); */
content: '';
width: 58px;
height: 58px;
background-image: url(./images/play.png);
transform: translate(-50%, -50%) scale(5);
opacity: 0;
transition: all .5s;
}
/* 2. hover效果：大按钮，看不见：透明是0 → 小按钮，看得见：透明度1 */
.box li:hover .pic::after {
transform: translate(-50%, -50%) scale(1);
opacity: 1;
}
</style>

4、 平面转换-倾斜
取值：
- 角度度数deg

div {
margin: 100px auto;
width: 100px;
height: 200px;
background-color: pink;
transition: all 0.5s;
}
div:hover {
transform: skew(30deg);
transform: skew(-30deg);
}
</style>
