【问题描述】：
我正在尝试使用 Angular 材质创建导航栏。所以我从几个设置开始：
1) 我用 npm 安装了 Angular 材质 2）我在style.css中配置了如下主题：
/* You can add global styles to this file, and also import other style files */
@import '~@angular/material/prebuilt-themes/deeppurple-amber.css';
@import '~https://fonts.googleapis.com/icon?family=Material+Icons';
3) 我将 Angular Material 主题链接到 index.html，如下所示：
<link href="../node_modules/@angular/material/prebuilt-themes/indigo-pink.css" rel="stylesheet">
<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
有关我的环境的更多信息，请查看我的 angular.json 文件：
