推荐答案
方法是 not ，方法是在<ngb-panel class="customclass1" title="Simple">上添加一个类，然后添加一个CSS规则，例如:
The way to do it is not by adding a class on <ngb-panel class="customclass1" title="Simple"> and then adding a css rule such as:
.customclass1{
background-color: yellow!important;
}
您最好通过以下方式添加CSS规则:
You would have a better time adding a css rule by:
ngb-accordion /deep/ .card /deep/ [role=tab]{
background-color: yellow;
}
ngb-accordion /deep/ .card /deep/ [role=tab]#\31 -header{
background-color: red !important;
}
到那时，您将能够根据ID自定义标签:
By then you would be able to customize the tab according to the id:
检查以下plnkr并注意src/accordion-basic.html和src/accordion-basic.css之间使用ID进行样式设置的区别:
Check the following plnkr and notice the difference between src/accordion-basic.html and src/accordion-basic.css for the styling using id:

http://plnkr.co/edit/izfDn4MO3QSjja8mBqq7?p=preview
请注意，/deep/与>>>和::ng-deep::一起已被已弃用，但您将可以使用它，直到将其删除.
Notice the /deep/ it was deprecated altogether with >>> and ::ng-deep:: but you would be able to use it until they're removed.
