el-popover ::after style overwrite bug All In One

overwrite bug ?

.table-custom-popover-class 与 .el-popper 或 .el-popper[x-placement^="top"]

类名同优先级

.table-custom-popover-class {
    min-width: 30px !important;
    width: auto !important;
    font-size: 12px !important;
    color: #FFFFFF !important;
    background: #303133 !important;
    .el-popper[x-placement^="top"] .popper__arrow,
    .el-popper[x-placement^="top"] .popper__arrow::after {
        border-top-color:#303133 !important;
        display: none !important;
        border-color: #303133 !important;
    }
}

solution

CSS 优先级 bug，同级别的多个 class, 后面 class 会覆盖前面的样式, 导致前面的样式失效 ?

.custom-popover-class {
    min-width: 30px !important;
    width: auto !important;
    font-size: 12px !important;
    color: #FFFFFF !important;
    background: #303133 !important;
}

.custom-popover-class .popper__arrow::after {
    border-top-color:#303133 !important;
}

/*
.custom-popover-class.el-popper[x-placement^="top"] .popper__arrow::after {
     border-top-color:#303133 !important;
}
*/
