transform案例

# transform案例

# 结合perspective和transform-style实现两面翻转盒子的效果

代码示例：

<div class="container-trans">
    <div class="content-trans">
        <div class="front">正面</div>
        <div class="back">反面</div>
    </div>
</div>

.container-trans {
    perspective: 800px; /*重点：开启3d透视效果*/
}

.content-trans {
    margin: 0 auto;
    width: 220px;
    height: 220px;
    line-height: 220px;
    font-size: 16px;
    text-align: center;
    position: relative;
    transform-style: preserve-3d; /*重点：开启子元素的3d效果*/
    transition: all 1s;
}

.content-trans:hover {
    transform: rotateY(180deg);
}

.front,
.back {
    position: absolute;
    width: 100%;
    height: 100%;
}

.front {
    background-color: violet;
    z-index: 999;
}

.back {
    background-color: yellow;
    transform: rotateY(180deg); /*重点：将背面展示的盒子先转过去*/
}
