Question

Alter the color scheme of the material dialog's background

I have been trying to change the background color of a dialog, but so far I have only been successful in changing the outline. I used the panelClass property as I believed it was the correct way to do it.

Answer №1

The reason why the outline property is effective while the background-color property isn't, stems from the fact that the test class is being applied to the dialog container rather than the dialog itself. This means that the background-color may be functioning on the container, but it remains unseen as the dialog covers it. On the other hand, the outline appears outside the dialog, hence its visibility.

Typically, when styling a component with a stylesheet, we use the :host selector like this:

:host{
    background-color: yellow;
}

Since you're not utilizing a stylesheet in your component, I enclosed your code within a <section> tag, as shown here:

<section class="dialogContainer">

  <h1 mat-dialog-title>Hi {{data.name}}</h1>
  <div mat-dialog-content>
    <p>What's your favorite animal?</p>
    <mat-form-field>
      <mat-label>Favorite Animal</mat-label>
      <input matInput [(ngModel)]="data.animal">
    </mat-form-field>
  </div>
  <div mat-dialog-actions>
    <button mat-button (click)="onNoClick()">No Thanks</button>
    <button mat-button [mat-dialog-close]="data.animal" cdkFocusInitial>Ok</button>
  </div>
  
</section>

I have now applied the background color to the <section> element in your styles.scss, as demonstrated below:

.dialogContainer{
  background-color: yellow;
}

As a result, the background now displays correctly.

In order to customize the appearance of a specific element, you must target it using the test class in your CSS. The code snippet below demonstrates how you can achieve this:

.test {
  .mat-mdc-dialog-surface.mdc-dialog__surface {
    border: 2px solid purple;
    background-color: black;
  }
}
