注意：1、写css样式不能加scoped 要在后面加上 !important才生效

  .contentAll {position: fixed;right: 0px;bottom: 0px;background-color: #fff;z-index: 2000 !important;width: 359px !important;.contentHead {width: 100%;height: 40px !important;background-color: #0087ff;display: flex;flex-direction: row;align-items: center;position: relative;padding-left: 20px;box-sizing: border-box;.my-custom-icon {width: 20px !important;height: 20px !important;background-image: url("~assets/images/allwarning/warning.png");background-size: cover;background-repeat: no-repeat;background-position: center center;}.my-custom-text {font-size: 18px;color: #ffffff;margin-left: 10px;}.my-custom-close {font-size: 18px;color: #ffffff;position: absolute;right: 15px;cursor: pointer;}}.contentDeatil {min-height: 100px !important;max-height: 280px !important;padding-left: 20px !important;padding-right: 20px !important;box-sizing: border-box;overflow: auto;.detailText {width: 100%;font-size: 16px !important;line-height: 30px !important;margin-top: 15px !important;margin-bottom: 15px !important;overflow: hidden;white-space: nowrap;text-overflow: ellipsis;&:hover {text-decoration: underline;cursor: pointer;}}}}
