React js example. Login form with css3 animation

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">
    <form id="login-form" class="form-horizontal" style={{/*width:58%;*/}}>
        <div class="col-md-3 text-center">
            <img src="https://bootdey.com/img/Content/avatar/avatar1.png" id="avtar" />
            <hr/>

        </div>
        <div class="col-md-6">
             <div class="form-group">
                <div class="col-sm-10">
                  <input type="email" class="form-control" id="inputEmail3" placeholder="Email"/>
                </div>
              </div>
              <div class="form-group">
                <div class="col-sm-10">
                  <input type="password" class="form-control" id="inputPassword3" placeholder="Password"/>
                </div>
              </div>
            <button class="btn btn-primary" type="submit">Log in</button>
        </div>
    </form>
</div>                    
		</div>
	);
}
export default App;

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

body {
    font-family: sans-serif;
    background-color: #108a93;
}

#login-form {
    position: absolute;
    left: 50%;
    top: 30%;
    margin-left: -110px;
    margin-top: -75px;
    -webkit-animation: login 1s ease-in-out;
    -moz-animation: login 1s ease-in-out;
    -ms-animation: login 1s ease-in-out;
    -o-animation: login 1s ease-in-out;
    animation: login 1s ease-in-out;
}

#avtar{
   border-radius: 6px;
   width:150px;
}
