title: react material ui not responsive when opened in mobile browser
body: <p>I'm trying to build a mobile web application using react material ui library. </p>
  
  <p>But it seems the material UI components are not responsive. They display very well on desktop, but when I open it on my mobile browser, the fonts are very small.</p>
  
  <p>Isn't material UI meant to be used to build mobile App? Why it's even not responsive? </p>
