title: Increase default font & field & etc size, on Angular Material?
body: <p>Building a website mostly for old people. If I zoom in to 300% it's about right. Without explicitly referencing every relevant HTML tag, how do I make this default?</p>
  
  <p>E.g.: is there a mixin or something?</p>
  
  <p>Or a button I can expose for people on tablets, to increase the zoom using browser native features?</p>
