无法覆盖 Angular 7 应用程序中的 Bootstrap [英] Not able to override Bootstrap in Angular 7 app

问题描述

在 angular 应用程序中，我试图通过移除分隔符来覆盖我的 breadcrumb.我使用 https://getbootstrap.com/docs/4.2/components/breadcrumb/#example.

In angular app i am trying to override my breadcrumb by removing the divider. i use https://getbootstrap.com/docs/4.2/components/breadcrumb/#example.

但不起作用.这是我的 angular.json

But not works. here is my angular.json

推荐答案

1. 从 angular.json 中删除 bootstrap.min.css.

....
"styles": [
   "node_modules/font-awesome/css/font-awesome.min.css",
   "src/styles/styles.scss",
],
....

导入 bootstrap.scss 文件.

@import "~bootstrap/scss/bootstrap";

在 @import 语句之前设置 $breadcrumb-divider.

$breadcrumb-divider: none;

@import "~bootstrap/scss/bootstrap";
...
