设置的颜色不显示

原因：没有导入主题

material

https://material.angular.io//theming

• Available pre-built themes:

deeppurple-amber.css
indigo-pink.css
pink-bluegrey.css
purple-green.css

解决方法：

1. If you're using Angular CLI, this is as simple as including one line in your styles.css file:

@import '@angular/material/prebuilt-themes/deeppurple-amber.css';

2. Alternatively, you can just reference the file directly in index.html. This would look something like:

<link href="node_modules/@angular/material/prebuilt-themes/indigo-pink.css" rel="stylesheet">

materialize

导入 node_modules/ materialize.css
