How to change mat-icon size in Material

In my case, this works perfectly. I use newest material (6.2.0)

CSS:

.icon {
    font-size: 36px;
}

HTML:

  <div class="icon">
    <mat-icon [inline]="true">done</mat-icon>
  </div>

The main thing is to set: [inline]="true"

From the API:

@Input() inline: boolean – Whether the icon should be inlined,
automatically sizing the icon to match the font size of the element
the icon is contained in.
