@Component元数据中指定的样式仅适用于该组件的模板内。不被嵌套在模板内的任何组件继承,也不被投射到组件中的任何内容继承。
由于ngb-carousel是组件内部的嵌套组件,所以必须将css包含在全局css文件中。
.carousel-control-prev-icon {
background-image: url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' fill='#{$carousel-control-color}' viewBox='0 0 8 8'%3E%3Cpath d='M5.25 0l-4 4 4 4 1.5-1.5-2.5-2.5 2.5-2.5-1.5-1.5z'/%3E%3C/svg%3E");
}否则,如果要从组件中添加样式,则可以使用::ng-deep。
::ng-deep .carousel-control-prev-icon {
background-image: url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' fill='#{$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");
}检查这个工作的stackblitz
FYI,::ng-deep是不推荐的,但它仍然是有角的。看看这。
