Angular Material Overriding Default Style of SnackBar Component

Question

I am attempting to override the default max-width of the snackbar component in Angular Material.

The CSS applied by Angular Material is shown below:

.mat

As of June 30, 2019, using Angular Material 8.0.1 with Angular 8.0.3, the following SCSS and typescript seems to work for overriding the color of the action button in an Angular Material snackbar *without using !important *:

styles.scss (not the extremely long duration, which allowed me to inspect the styling before it disappeared):

$snackBarTextColor: white;
$snackBarBackgroundNormal: #087a51;
$snackBarActionColor: lightgray;
.snackBarInfo {
    background-color: $snackBarBackgroundNormal;
    color: $snackBarTextColor;


}
.mat-simple-snackbar > span {
    font-weight: bold;
}
.mat-simple-snackbar-action {
    .mat-button {
        .mat-button-wrapper {
            color: $snackBarActionColor;
        }
    }
}

app.module.ts:

import { MAT_SNACK_BAR_DEFAULT_OPTIONS } from '@angular/material/snack-bar';
providers: [
        {
            provide: MAT_SNACK_BAR_DEFAULT_OPTIONS,
            useValue: {
                duration: 41000,
                horizontalPosition: 'center',
                verticalPosition: 'bottom',
                panelClass: 'snackBarInfo'
            }
        }
    ]
