我为轮播开发了一个功能,我想更改图标(下一个图标和上一个图标)的颜色,可以吗?和thnak的(我使用Angular 5)
file.html:
<ngb-carousel [interval]="3000">
<ng-template ngbSlide> ... </ng-template>
<ng-template ngbSlide> ... </ng-template>

@Component元数据中指定的样式仅适用于该组件的模板。 模板中嵌套的任何组件或组件中投影的任何内容都不会继承它们。
由于ngb-carousel是组件内部的嵌套组件,因此必须在全局css文件中包含css。
.carousel-control-prev-icon {
background-image: url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' fill='#{$carousel-control-color}' viewBox='0 0 8 8'%3E%3Cpath d='M5.25 0l-4 4 4 4 1.5-1.5-2.5-2.5 2.5-2.5-1.5-1.5z'/%3E%3C/svg%3E");
}
否则,如果您要从组件之一添加样式,则可以使用::ng-deep
::ng-deep .carousel-control-prev-icon {
background-image: url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' fill='#{$carousel-control-color}' viewBox='0 0 8 8'%3E%3Cpath d='M5.25 0l-4 4 4 4 1.5-1.5-2.5-2.5 2.5-2.5-1.5-1.5z'/%3E%3C/svg%3E");
}

仅供参考,::ng-deep
