Overriding Angular Material body typography

Question

I've created a custom theme using Angular Material (v 5.2.4) in an Angular (v 5.2.0) app.

my-theme.scss:

@import '~@angular/material/theming';

@import url('https://fonts.googleapis.com/css?family=IBM+Plex+Sans+Condensed:300,400,500');

@include mat-core();

$my-theme-primary: mat-palette($mat-deep-orange);
$my-theme-accent:  mat-palette($mat-amber, A200, A100, A400);
$my-theme:   mat-light-theme($my-theme-primary, $my-theme-accent);
$my-typography: mat-typography-config(
  $font-family: '"IBM Plex Sans Condensed"'
);

.my-theme {
  @include angular-material-theme($my-theme);
  @include angular-material-typography($my-typography);
}

I've also added the class names mat-app-background mat-typography to the body in the index.html page for my app.

When I add the my-theme class to the container of my app (inside the body), then all of the material components do get the custom font (for things like radio button labels, etc), but nothing outside of a component gets it.

I've also tried using the angular-material-typography() and mat-base-typography() mixins to no avail.

How can I override the fonts from the mat-typography class?

    @import '~@angular/material/theming';
    @import './color_palette.scss'; // contains custom palette
    @import './app_theme.scss'; // contains app mixin

   $app-typography: mat-typography-config(
      $font-family: 'Muli, Roboto, "Helvetica Neue", sans-serif',
      $display-4:     mat-typography-level(112px, 112px, 300),
      $display-3:     mat-typography-level(56px, 56px, 400),
      $display-2:     mat-typography-level(45px, 48px, 400),
      $display-1:     mat-typography-level(34px, 40px, 400),
      $headline:      mat-typography-level(24px, 32px, 400),
      $title:         mat-typography-level(20px, 32px, 500),
      $subheading-2:  mat-typography-level(16px, 28px, 400),
      $subheading-1:  mat-typography-level(15px, 24px, 400),
      $body-2:        mat-typography-level(14px, 24px, 500),
      $body-1:        mat-typography-level(14px, 20px, 400),
      $caption:       mat-typography-level(12px, 20px, 400),
      $button:        mat-typography-level(14px, 14px, 500),
        // Line-height must be unit-less fraction of the font-size.
      $input:         mat-typography-level(16px, 1.25, 400)
    );

    @include mat-core($app-typography);

    $primary: mat-palette($deeppurple); // $deeppurple form color_palette
    $accent:  mat-palette($blue);  // $blue form color_palette
    $warn:    mat-palette($red);  // $red form color_palette
    $theme:   mat-light-theme($primary, $accent, $warn);
    @include  app-theme($theme);  //app mixin from app_theme

    body, html {
      margin: 0;
      height: 100%;
      font-size: mat-font-size($app-typography, body-1);
      font-family: mat-font-family($app-typography);
      line-height: mat-line-height($app-typography, body-1);
    }

Answer 2

The accepted question pointed me in the right direction, this is how I ended up getting it working, for future reference:

@import '~@angular/material/theming';

@import url('https://fonts.googleapis.com/css?family=IBM+Plex+Sans+Condensed:300,400,500');

@include mat-core();

$my-theme-primary: mat-palette($mat-deep-orange);
$my-theme-accent:  mat-palette($mat-amber, A200, A100, A400);
$my-theme:   mat-light-theme($my-theme-primary, $my-theme-accent);
$my-typography: mat-typography-config(
  $font-family: '"IBM Plex Sans Condensed"'
);

.my-theme {
  @include angular-material-theme($my-theme);

  // this is what fixed it
  .mat-typography & {
    font-size: mat-font-size($my-typography, body-1);
    font-family: mat-font-family($my-typography, body-1);
    line-height: mat-line-height($my-typography, body-1);

    h1, h2, h3 {
      font-family: mat-font-family($my-typography, body-1);
    }
  }
}
