如何使用引导程序将 css 应用于列表工具提示

Question

我想将 css 应用于我的工具提示，我希望我的工具提示的背景为灰色，文本为粗体。

问题是我真的不知道该怎么做，特别是因为我有一个包含很多选项的列表并且每个选项都有自己的工具提示，我想将 css 应用于我的选项中的工具提示列表。

这是我列表中的代码：

<select id="worker" class="form-control" [(ngModel)]="selectedExportWorker" [formControl]="workerForm.controls['selectedExportWorker']" (ngModelChange)="selectWorker()">
   <option [ngValue]="blankObject"></option>
   <option *ngFor="let worker of workerExportList; index as i" [ngValue]="worker" class="tooltip" data-toggle="tooltip" data-placement="top" title="{{info_bulle_export[i]}}">{{worker.label}}</option>
</select>

这是我目前拥有的工具提示的结果：

这是我想要获得的工具提示示例：
