Question

您好，我正在Angular 5中开发Web应用程序。我正在尝试开发手风琴，并且正在关注https://codepen.io/rugor/pen/hwyzn。我已经使用angular cli创建了Angular 5应用。之后，在已安装的引导程序和通过npm的Jquery中。我从Codepen复制了相同的代码。下面是我的angular.json文件，其中包含引导程序和jquery的链接。

    }

}

每当我运行代码时，所有内容均显示为纯文本，如下图所示。我可以知道不应用引导样式的原因是什么？有人可以帮我吗？任何帮助，将不胜感激。谢谢

您在angular.json配置中缺少引导CSS文件

尝试在脚本属性级别添加styles属性

"styles": [
  "node_modules/bootstrap/dist/css/bootstrap.min.css"
],

Bootstrap手风琴不能在Angular 5中使用？
