ng-add: option to set up typography styles for native elements

[TimoPot]

Reproduction

Steps to reproduce:

1. create new angular app

2. do: ng add @angluar/material
   result:
   added 3 packages from 4 contributors in 15.766s
   UPDATE src/main.ts (391 bytes)
   UPDATE src/app/app.module.ts (577 bytes)
   UPDATE angular.json (3608 bytes)
   UPDATE src/index.html (490 bytes)
   UPDATE src/styles.css (181 bytes)

3. notice that in index.html the fonts links are added but the body tag has no class

Expected Behavior

The schematic should add class="mat-typography" to the body tag in index.html

Actual Behavior

The schematic changes the index.html to add font links but did not change the body tag

Environment

• Angular: 8.1.1
• CDK/Material: 8.1.1
• Operating System (e.g. Windows, macOS, Ubuntu): Windows

[Totati]

In the documentation this is mentioned.

[TimoPot]

Yes you’re correct.
But the schematic does all the steps in the documentation to except this step.
And if a user is not aware of that then no typography is applied and the user wont know why.

@jelbourn Do we actually want to do this as part of ng add. How about adding an option (with prompt) for this?

[jelbourn]

Seems reasonable as a prompt in ng add.

[LayZeeDK]

In @angular/[email protected], this prompt is here:

? Set up global Angular Material typography styles?

but the mat-typography class is added to the body tag no matter what we answer.
