无法覆盖 Angular 7 应用中的 Bootstrap
Not able to override Bootstrap in Angular 7 app
在 angular 应用程序中,我试图通过删除分隔符来覆盖我的 breadcrumb
。我用 https://getbootstrap.com/docs/4.2/components/breadcrumb/#example
.
但是不行。这是我的 angular.json

有人帮帮我吗?提前致谢。
不为 bootstrap 样式导入或使用 CDN,而是使用 angular.json 加载 bootstrap.css,如下所示。顺序应该是先bootstrap.css然后style.css
"styles": [
"../node_modules/bootstrap/dist/css/bootstrap.min.css",
"src/styles/styles.scss",
],
您可以使用下面的 css 来覆盖分隔符。这不会覆盖 bootstrap 变量。
.breadcrumb>li+li:before {
padding: 0 5px;
color: #ccc;
content: "";
}
覆盖 bootstrap 变量 put "$breadcrumb-divider: none;"在 style.scss.
的顶部
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";
...
- 打开
angular.json
- 将
"extractCss": true
更改为 "extractCss": false
应该可以解决问题
最新 angular 版本的两个简单步骤
1).在 angular.json 文件中,在 bootstrap 相关样式表之后添加您的自定义样式表,就像我在代码片段
中添加的一样
"styles": [
"./node_modules/bootstrap/dist/css/bootstrap.min.css",
"src/styles.css"
],
2).最后 运行 您的应用程序再次使用 ng serve
命令
