title: Components overlapping each other in React
body: <p>I am rendering 2 components in my React application, which should show one after the other on the screen. But they are overlapping. Also the layout is also not how I expected it to be, <a href="https://i.stack.imgur.com/Er5uW.png" rel="noreferrer">see photo of error</a>. I am not able to figure out the cause. Link to actual project: <a href="https://evening-coast-59870.herokuapp.com/register" rel="noreferrer">https://evening-coast-59870.herokuapp.com/register</a></p>
  
  <p>Here is my main component App.js which renders Navbar, Login and Register components as per the route.</p>
  
  <pre><code>import React, { Fragment } from "react";
  import "./App.css";
  import { BrowserRouter as Router, Route, Switch } from "react-router-dom";
  import Navbar from "./components/layout/Navbar";
  import Landing from "./components/layout/Landing";
  import Login from "./components/auth/Login";
  import Register from "./components/auth/Register";
  
  const App = () =&gt; (
  &lt;Router&gt;
  &lt;Fragment&gt;
    &lt;Navbar /&gt;
  
    &lt;Switch&gt;
      &lt;Route exact path="/" component={Landing} /&gt;
      &lt;Route exact path="/login" component={Login} /&gt;
      &lt;Route exact path="/register" component={Register} /&gt;
    &lt;/Switch&gt;
  &lt;/Fragment&gt;
  &lt;/Router&gt;
  );
  
  export default App;
  </code></pre>
  
  <p>Register.js:</p>
  
  <pre><code>import React, { Fragment } from "react";
  import { Link } from "react-router-dom";
  const Register = () =&gt; {
  return (
  &lt;Fragment&gt;
    &lt;h1 className="large text-primary"&gt;Sign Up&lt;/h1&gt;
    &lt;p className="lead"&gt;
      &lt;i className="fas fa-user"&gt;&lt;/i&gt; Create Your Account
    &lt;/p&gt;
