title: how to increase font size of ionic app according the device font size
body: <p>I am developing an Ionic 4 application, I have a defined <code>font-size</code> of <code>14px</code> in the app but there is an android native setting called &quot;<code>font-size</code>&quot; where users can make the size of texts on the phone bigger or smaller.</p>
  <p>people can choose 'big' or even 'huge' text size and unfortunately, this affects the text size of the app on the phone and ruins the layout.</p>
  <blockquote>
  <p>eg: text on the button goes out of the defined box if device font-size
  is huge.</p>
  </blockquote>
  <p>I know that there is an <code>accessibility plugin</code> available that can help me to keep the app's<code> font-size</code> size as it is but I don't want that.</p>
  <p>Is there any way to increase the font size of the app according to the font size of the user's device in ionic?</p>
