React js example. bs4 beta login

Preview Code

1. First, we need fresh reactjs setup, and for that, we need to run below commands into out terminal, and also we should have latest node version installed on our system:

npx create-react-app my-awesome-project

cd my-awesome-project

npm start

2. Now we need to run below commands into our project terminal to get bootstrap and related modules into our reactjs application:

npm install [email protected] --save

npm start //For start project again

3. Finally for the main output, we need to add below code into our my-awesome-project/src/App.js file or if you have fresh setup then you can replace my-awesome-project/src/App.js file code with below code:

import React from 'react';
import './App.css';
import 'bootstrap/dist/css/bootstrap.min.css';


function App() {
  
	return (
		<div>
			<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css" rel="stylesheet"/>
<br/>
<br/>
<div class="container">
    <div class="row justify-content-center">
      <div class="col-md-8">
        <div class="card-group mb-0">
          <div class="card p-4">
            <div class="card-body">
              <h1>Login</h1>
              <p class="text-muted">Sign In to your account</p>
              <div class="input-group mb-3">
                <span class="input-group-addon"><i class="fa fa-user"></i></span>
                <input type="text" class="form-control" placeholder="Username"/>
              </div>
              <div class="input-group mb-4">
                <span class="input-group-addon"><i class="fa fa-lock"></i></span>
                <input type="password" class="form-control" placeholder="Password"/>
              </div>
              <div class="row">
                <div class="col-6">
                  <button type="button" class="btn btn-primary px-4">Login</button>
                </div>
                <div class="col-6 text-right">
                  <button type="button" class="btn btn-link px-0">Forgot password?</button>
                </div>
              </div>
            </div>
          </div>
          <div class="card text-white bg-primary py-5 d-md-down-none" style={{/*width:44%*/}}>
            <div class="card-body text-center">
              <div>
                <h2>Sign up</h2>
                <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
                <button type="button" class="btn btn-primary active mt-3">Register Now!</button>
              </div>
            </div>
          </div>
        </div>
      </div>
    </div>
  </div>
		</div>
	);
}
export default App;

4. Now we need to add below code into our my-awesome-project/src/App.css file :

body{
    margin-top:20px;
    background:#eee;
}
.container {
    margin-right: auto;
    margin-left: auto;
    padding-right: 15px;
    padding-left: 15px;
    width: 100%;
}

@media (min-width: 576px) {
    .container {
        max-width: 540px;
    }
}

@media (min-width: 768px) {
    .container {
        max-width: 720px;
    }
}

@media (min-width: 992px) {
    .container {
        max-width: 960px;
    }
}

@media (min-width: 1200px) {
    .container {
        max-width: 1140px;
    }
}



.card-columns .card {
    margin-bottom: 0.75rem;
}

@media (min-width: 576px) {
    .card-columns {
        column-count: 3;
        column-gap: 1.25rem;
    }
    .card-columns .card {
        display: inline-block;
        width: 100%;
    }
}
.text-muted {
    color: #9faecb !important;
}

p {
    margin-top: 0;
    margin-bottom: 1rem;
}
.mb-3 {
    margin-bottom: 1rem !important;
}

.input-group {
    position: relative;
    display: flex;
    width: 100%;
}
