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>
			<div class="container h-100">
    		<div class="row h-100">
				<div class="col-sm-10 col-md-8 col-lg-6 mx-auto d-table h-100">
					<div class="d-table-cell align-middle">

						<div class="text-center mt-4">
							<h1 class="h2">Welcome back, Dey</h1>
							<p class="lead">
								Sign in to your account to continue
							</p>
						</div>

						<div class="card">
							<div class="card-body">
								<div class="m-sm-4">
									<div class="text-center">
										<img src="https://bootdey.com/img/Content/avatar/avatar6.png" alt="Andrew Jones" class="img-fluid rounded-circle" width="132" height="132"/>
									</div>
									<form>
										<div class="form-group">
											<label>Email</label>
											<input class="form-control form-control-lg" type="email" name="email" placeholder="Enter your email"/>
										</div>
										<div class="form-group">
											<label>Password</label>
											<input class="form-control form-control-lg" type="password" name="password" placeholder="Enter your password"/>
											<small>
            <a href="pages-reset-password.html">Forgot password?</a>
          </small>
										</div>
										<div>
											<div class="custom-control custom-checkbox align-items-center">
												<input type="checkbox" class="custom-control-input" value="remember-me" name="remember-me" checked=""/>
												<label class="custom-control-label text-small">Remember me next time</label>
											</div>
										</div>
										<div class="text-center mt-3">
											<a href="index.html" class="btn btn-lg btn-primary">Sign in</a>
											
										</div>
									</form>
								</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{
    background-color: #DCDCDC;
    margin-top:20px;
}
.card {
    margin-bottom: 1.5rem;
    box-shadow: 0 1px 15px 1px rgba(52,40,104,.08);
}

.card {
    position: relative;
    display: -ms-flexbox;
    display: flex;
    -ms-flex-direction: column;
    flex-direction: column;
    min-width: 0;
    word-wrap: break-word;
    background-color: #fff;
    background-clip: border-box;
    border: 1px solid #e5e9f2;
    border-radius: .2rem;
}
