Trouble shooting Material styles not loading on mat-button Angular 7?

Question

I created an app with ng new and added Material with ng add @angular/material. When I run ng serve I do not see to have the material style.css loaded despite having in my angular.json

"architect": {
  "build": {                                                         
    "options": {
      "styles": [                                                    
        "./node_modules/@angular/material/prebuilt-themes/indigo-pink.css",                                                                     
        "src/styles.scss"                                            
      ],                                                             
  ...                           

What else am I missing? When I look at the chrome dev console, I see it's loading

• content_scripts.css
• frontend.css
• shadow.css

And one css for the fonts (fonts?family..) and one for the icons icon?family..

I've also tried adding to my styles.scss the following,

@import "~@angular/material/prebuilt-themes/indigo-pink.css"; 

Which also resulted in no additional css files being brought in.

I had a similar issue in Angular 12. I imported the MaterialModule in App Module, but that did not apply the colors. So I fixed it by including the following css file import in the styles.scss file of Angular project. @import '~@angular/material/prebuilt-themes/purple-green.css';

So here's the complete solution:

material.module.ts

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';

import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { MatCheckboxModule } from '@angular/material/checkbox';
import { MatButtonModule } from '@angular/material/button';
import { MatInputModule } from '@angular/material/input';
import { MatAutocompleteModule } from '@angular/material/autocomplete';
import { MatDatepickerModule } from '@angular/material/datepicker';
import { MatFormFieldModule } from '@angular/material/form-field';
import { MatRadioModule } from '@angular/material/radio';
import { MatSelectModule } from '@angular/material/select';
import { MatSliderModule } from '@angular/material/slider';
import { MatSlideToggleModule } from '@angular/material/slide-toggle';
import { MatMenuModule } from '@angular/material/menu';
import { MatSidenavModule } from '@angular/material/sidenav';
import { MatBadgeModule } from '@angular/material/badge';
import { MatToolbarModule } from '@angular/material/toolbar';
import { MatListModule } from '@angular/material/list';
import { MatGridListModule } from '@angular/material/grid-list';
import { MatCardModule } from '@angular/material/card';
import { MatStepperModule } from '@angular/material/stepper';
import { MatTabsModule } from '@angular/material/tabs';
import { MatExpansionModule } from '@angular/material/expansion';
import { MatButtonToggleModule } from '@angular/material/button-toggle';
import { MatChipsModule } from '@angular/material/chips';
import { MatIconModule } from '@angular/material/icon';
import { MatProgressSpinnerModule } from '@angular/material/progress-spinner';
import { MatProgressBarModule } from '@angular/material/progress-bar';
import { MatDialogModule } from '@angular/material/dialog';
import { MatTooltipModule } from '@angular/material/tooltip';
import { MatSnackBarModule } from '@angular/material/snack-bar';
import { MatTableModule } from '@angular/material/table';
import { MatSortModule } from '@angular/material/sort';
import { MatPaginatorModule } from '@angular/material/paginator';
import { MatDividerModule } from '@angular/material/divider';


@NgModule( {
  imports: [
    CommonModule,
    BrowserAnimationsModule,
    MatCheckboxModule,
    MatCheckboxModule,
    MatButtonModule,
    MatInputModule,

    MatTableModule,
    MatSortModule,
    MatPaginatorModule,
  ],
  providers: [
    MatDatepickerModule,
  ]
} )

export class MaterialModule { }

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';

import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { MaterialModule } from './material/material.module'; // For Angular Material support
import { FlexLayoutModule } from "@angular/flex-layout"; // For Angular Flex layout

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    BrowserAnimationsModule,
    MaterialModule,
    FlexLayoutModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

styles.scss

@import '~@angular/material/prebuilt-themes/purple-green.css';

Hope the above solution helps someone.

If the file angular.json is setup correctly, do check if your components attribute color setup properly, i.e.

<mat-component color="primary">

Answer 3

For me, I had created buttons that were unstyled. I actually copied the example from the docs on menu. I didn't realize that the buttons in the example needed more than just that which was documented in the API tab. They otherwise worked with just,

import {MatButtonModule} from '@angular/material/button';

So when I ran that import in my app's module.ts and added it to my imports array it worked. As to why manually including the style with a <link> element didn't work,I was getting the following error when I tried that:

Refused to apply style from 'http://localhost:4200/node_modules/@angular/material/prebuilt-themes/indigo-pink.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

As for the @import in styles.scss, it seems to be a NOP with Angular 7 if you have

@import "~@angular/material/prebuilt-themes/indigo-pink.css"; 

If you also have it configured in your angular.json. Everything is working now without the @import statement anywhere.

Please remove the css import from angular.json and put it into your styles.scss file.

So it will look like this.

angular.json

"architect": { "build": { ... "styles": [ "src/styles.scss" ], ... },

styles.scss

@import '~@angular/material/prebuilt-themes/indigo-pink.css';

If you have issue with upper one add the below lines to styles.scss

@import '~@angular/material/theming'; // Plus imports for other components in your app. // Include the common styles for Angular Material. We include this here so that you only // have to load a single css file for Angular Material in your app. // Be sure that you only ever include this mixin once! @include mat-core(); // Define the palettes for your theme using the Material Design palettes available in palette.scss // (imported above). For each palette, you can optionally specify a default, lighter, and darker // hue. Available color palettes: https://material.io/design/color/ $candy-app-primary: mat-palette($mat-indigo); $candy-app-accent: mat-palette($mat-pink, A200, A100, A400); // The warn palette is optional (defaults to red). $candy-app-warn: mat-palette($mat-red); // Create the theme object (a Sass map containing all of the palettes). $candy-app-theme: mat-light-theme($candy-app-primary, $candy-app-accent, $candy-app-warn); // Include theme styles for core and each component used in your app. // Alternatively, you can import and @include the theme mixins for each component // that you are using. @include angular-material-theme($candy-app-theme);

I just paste it from docs.

Also you can add this to index.html by following code

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

Let me know if its work or you need anything else.
