React js example. Login form with background image

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 bootstrap snippets bootdey">
    <div class="row">
        <div class="col-md-4 col-md-offset-7">
            <div class="panel panel-default">
                <div class="panel-heading"> <strong class="">Login</strong>

                </div>
                <div class="panel-body">
                    <form class="form-horizontal" role="form">
                        <div class="form-group">
                            <label for="inputEmail3" class="col-sm-3 control-label">Email</label>
                            <div class="col-sm-9">
                                <input type="email" class="form-control" id="inputEmail3" placeholder="Email" required=""/>
                            </div>
                        </div>
                        <div class="form-group">
                            <label for="inputPassword3" class="col-sm-3 control-label">Password</label>
                            <div class="col-sm-9">
                                <input type="password" class="form-control" id="inputPassword3" placeholder="Password" required=""/>
                            </div>
                        </div>
                        <div class="form-group">
                            <div class="col-sm-offset-3 col-sm-9">
                                <div class="checkbox">
                                    <label class="">
                                        <input type="checkbox" class=""/>Remember me</label>
                                </div>
                            </div>
                        </div>
                        <div class="form-group last">
                            <div class="col-sm-offset-3 col-sm-9">
                                <button type="submit" class="btn btn-success btn-sm">Sign in</button>
                                <button type="reset" class="btn btn-default btn-sm">Reset</button>
                            </div>
                        </div>
                    </form>
                </div>
                <div class="panel-footer">Not Registered? <a href="#/" class="">Register here</a>
                </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 :

/* CSS used here will be applied after bootstrap.css */

body { 
 background: url('https://bootdey.com/img/Content/bg1.jpg') no-repeat center center fixed; 
 -webkit-background-size: cover;
 -moz-background-size: cover;
 -o-background-size: cover;
 background-size: cover;
}

.panel-default {
 opacity: 0.9;
 margin-top:30px;
}
.form-group.last {
 margin-bottom:0px;
}
