title: React component not showing on mobile after button onClick but working perfectly fine on desktop
body: <p>I made an app that renders a basic sign-in form and sends a fetch request with the username and password, and after clicking the sign-in button another component gets rendered, that opens the google sign-in page in another tab returning a code that needs to be pasted in the component.
  Everything works great on the desktop; on a mobile, on the other hand, the second component doesn't get rendered.
  I think it might be a problem with the CSS, but I'm not sure.</p>
