title: Angular material 2 change font size
body: <p>I have added my custom theme file and I want to reduce font size through out the site. I don't know how change font size through custom theme as there's no proper documentation for this.</p>
  
  <pre><code>@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.
  $candy-app-primary: mat-palette($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);
