[英]Not able to override Bootstrap in Angular 7 app
在 angular 應用程序中,我試圖通過移除分隔線來覆蓋我的breadcrumb
。 我使用https://getbootstrap.com/docs/4.2/components/breadcrumb/#example
。
但不起作用。 這是我的 angular.json

我的style.scss:
@import '~bootstrap/scss/_functions.scss';
@import '~bootstrap/scss/_variables.scss';
@import '~bootstrap/scss/mixins/_breakpoints.scss';
@import 'global.scss';
$grid-breakpoints: (
sm: 768px,
md: 768px,
lg: 1024px
);
$container-min-widths: (
sm: 768px,
md: 768px,
lg: 1024px
);
//resets;-
html,body{
padding: 0;
margin: 0;
height: 100%;
}
.wrapper.container-fluid{
min-height: 100%;
padding:0;
margin: 0;
}
$breadcrumb-divider: none !important;
有人幫我嗎? 提前致謝。
使用 angular.json 加載 bootstrap.css,而不是為引導樣式導入或使用 CDN,如下所示。 順序應該是首先 bootstrap.css 然后是 style.css
"styles": [
"../node_modules/bootstrap/dist/css/bootstrap.min.css",
"src/styles/styles.scss",
],
您可以使用下面的 css 來覆蓋分隔線。 這不會覆蓋引導程序變量。
.breadcrumb>li+li:before {
padding: 0 5px;
color: #ccc;
content: "";
}
要覆蓋引導程序變量 put "$breadcrumb-divider: none;" 在 style.scss 的頂部。
從 angular.json 中刪除bootstrap.min.css
。
.... "styles": [ "node_modules/font-awesome/css/font-awesome.min.css", "src/styles/styles.scss", ], ....
導入bootstrap.scss
文件。
@import "~bootstrap/scss/bootstrap";
在@import
語句之前設置$breadcrumb-divider
。
$breadcrumb-divider: none; @import "~bootstrap/scss/bootstrap"; ...
最新 Angular 版本的兩個簡單步驟
1)。 在 angular.json 文件中,在引導程序相關的樣式表之后添加您的自定義樣式表,就像我在代碼片段中添加的那樣
"styles": [
"./node_modules/bootstrap/dist/css/bootstrap.min.css",
"src/styles.css"
],
2)。 最后,使用ng serve
命令再次手動運行您的應用程序
angular.json
"extractCss": true
更改為"extractCss": false
應該可以解決問題
