element下拉框背景/选中/鼠标移入样式设置

问题在页面内写穿透无效

<style lang="scss" scoped>
// 这个有效
  ::v-deep .el-input--mini .el-input__inner {
            background: transparent;
            color: #fff;
            border: 1px solid #093B9E;
        }
style>

直接在标签内写

<style>
.el-select-dropdown__list {
    background: rgba(21, 32, 68, 0.9);
    border: 1px solid #093B9E;
}

.el-select-dropdown {
    border: none;
    z-index: 100000 !important;
    background-color: #093B9E;
}

.el-select-dropdown__item.selected {
    color: #fff;
    background: #3879FA;
}

.el-select-dropdown__item {
    color: #fff;
}
/* 鼠标移入样式 */
.el-select-dropdown__item:hover {
    color: #fff;
    background: #093B9E;
}
</style>
