Angular 5 Material Snackbar panelClass config

Question

I am trying to add a panelClass config to the Angular Material Snackbar.

I wrote the following code, by following documentations from the official websites.

Answer 1

In angular 7 using ::ng-deep in front of class worked for me.

::ng-deep  .snackBar-fail {
    color: #ffffff !important;
    background-color: #cc3333 !important;
}
