React js example. Floating label css

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">
    <div class="jumbotron">
		<h1>Floating label css</h1>
	</div>
    
    <div class="col-md-5 col-md-offset-1">
		<form role="form"  id="floating-label">
		
			<div class="form-group">
				<label class="control-label">First Name</label>
				<input type="text" class="form-control" />
			</div>

			<div class="form-group">
				<label class="control-label">Last Name</label>
				<input type="text" class="form-control"/>
			</div>
		
		</form>
	</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;}

#floating-label .form-group {
    									display: flex;
										height: 55px;
									}

									#floating-label .control-label {
										font-size: 16px;
										font-weight: 400;
										opacity: 0.4;
										pointer-events: none;
										position: absolute;
										transform: translate3d(6px, 22px, 0) scale(1);
										transform-origin: left top;
										transition: 240ms;
									}

									#floating-label .form-group.focused .control-label {
										opacity: 1;
										transform: scale(0.75);
									}

									#floating-label .form-control {
										align-self: flex-end;
									}

									#floating-label .form-control::-webkit-input-placeholder {
										color: transparent;
										transition: 240ms;
									}

									#floating-label .form-control:focus::-webkit-input-placeholder {
										transition: none;
									}

									#floating-label .form-group.focused .form-control::-webkit-input-placeholder {
										color: #bbb;
									}
