详解vue2.0 transition 多个元素嵌套使用过渡

<div id='demo'>    <button @click="show = !show">按钮</button>    <transition name='move'>      <div class="v-d" v-show="show">        <div class='in in_move'></div>      </div>    </transition>  </div>

//css.v-d{      width:50px;      height:50px;      padding:10px;      transition: all 0.4s linear    }    .v-d .in{      width:30px;      height:30px;      background:#000;      transition: all 0.4s linear    }    .move-enter-active, .move-leave-active{      transition: all 0.4s linear    }     .move-enter, .move-leave-active{      opacity: 0;      transform: translateX(30px);    }     .move-enter, .move-leave-active .in{      transform: rotate(45deg)    }   

//jswindow.onload = function(){    new Vue({     el: '#demo',     data: {      show: false     }    })  }

.move-enter, .move-leave-active .in{  transform: rotate(180deg)} 

<transition name='move'> <div class="v-d">  <div class='in in_move'></div> </div></transition>.move-enter, .move-leave-active .in_move{  transform: rotate(180deg)}
