.slider{ width: 100%; height:200px; position: relative; user-select: none; .content{ position: absolute; left: 0; right: 0; top: 0; bottom: 0; background:green; z-index: 100; // 设置过渡动画 transition: 0.3s;

}
.remove{
  position: absolute;
  width:200px;
  height:200px;
  background:red;
  right: 0;
  top: 0;
  color:#fff;
  text-align: center;
  font-size: 40px;
  line-height: 200px;
}

}

效果,使用v-bind:style="deleteSlider" }
