遮罩层按钮事件失效

项目场景：

鼠标悬浮在图片上时，显示删除按钮。点击完成删除操作，

问题描述：

实现完页面效果时，点击删除标识不能触发删除事件。

原因分析：

可能是遮罩层，挡住了按钮事件。

解决方案：

1. 在遮罩层添加pointer-events:none;样式

   .mask{
       position:absolute;
       background:rgba(101,101,101,0.6);
       color:#ebe3e3;
       opacity: 0;
       top: 0;
       right: 0;
       width: 100%;
       height: 100%;
       border-radius: 10px;
       pointer-events:none;
   }
   

2. 在点击元素上，添加pointer-events:auto样式

   <i class="el-icon-delete" style="pointer-events:auto" @click="adjustment_del(index)">i>h3>
