      <button @click="isShow=false">按钮</button>
    </div>
  </transition>
</template>
<script>
export default {
  data() {
    return {
      isShow: false
    }
  }
}
</script>
<style>
#child {
  display: flex;
  justify-content: center;
  align-items: center;
  position: fixed;
  left: 0;
  right: 0;
  bottom: 70px;
  top: 0;
  background-color: green;
}
.slide-enter-active,
.slide-leave-active {
  transition: all 0.2s linear;
}
.slide-enter,
.slide-leave-to {
  transform: translate3d(100%, 0, 0);
}
.slide-enter-to,
.slide-leave {
  transform: translate3d(0, 0, 0);
}
</style>
