/scriptcss本来不该放出来但是我在这里踩坑了觉得其他人也会img图片有默认的拖拽很难禁止所以拿一个伪元素直接放在img上面不给点img就不会踩坑 .range {width: 960px;height: 540px;background-color: pink;position: relative;.iconItem {position: absolute;left: 10px;top: 10px;z-index: 2;display: flex;align-items: center;cursor: move;user-select: none;width: 32px;height: 32px;background: yellow;img {width: 32px;height: 32px;}// 关键::before {content: ;width: 100%;height: 100%;position: absolute;top: 0;left: 0;z-index: 3;}:hover {// span {// display: block;// }}span {display: none;font-size: 12px;font-family: YouSheBiaoTiHei;color: red;}}}完整代码建议按照上面的一点点复制吧有几个文件是外部的base64图片
