Build a Login Form with React & Tailwind CSS
By Braincuber Team
Published on January 16, 2026
Building authentication interfaces is fundamental to web development. A well-designed login form creates the first impression of your application's security and professionalism. This hands-on guide walks you through creating a polished, accessible login form using React's component architecture paired with Tailwind CSS's utility-first styling approach.
Whether you're building a SaaS dashboard, e-commerce platform, or internal tool, mastering form creation with these technologies gives you the foundation for scalable, maintainable authentication flows.
What You'll Build:
- Responsive login form with email and password fields
- Modern glassmorphism design with smooth animations
- Accessible form elements with proper labeling
- Form validation and state management
- Reusable component structure
Prerequisites
Node.js 18+
JavaScript runtime for development
HTML & JavaScript
Basic web development knowledge
Terminal Access
Command line for running scripts
Step 1: Initialize Your React Project
Start by creating a fresh React application. We'll use Create React App for quick setup, though you could also use Vite for faster builds.
npx create-react-app secure-login-form
cd secure-login-form
Next, install Tailwind CSS along with its peer dependencies:
npm install -D tailwindcss@3 postcss autoprefixer
npx tailwindcss init -p
Configure Tailwind
Update tailwind.config.js to scan your React files:
/** @type {import('tailwindcss').Config} */
module.exports = {
content: [
"./src/**/*.{js,jsx,ts,tsx}",
],
theme: {
extend: {},
},
plugins: [],
}
Add Tailwind directives to src/index.css:
@tailwind base;
@tailwind components;
@tailwind utilities;
Step 2: Build the Login Form Component
Create src/components/LoginForm.jsx with a modern, accessible design:
import React, { useState } from 'react';
function LoginForm() {
const [email, setEmail] = useState('');
const [password, setPassword] = useState('');
const [isLoading, setIsLoading] = useState(false);
const handleSubmit = async (e) => {
e.preventDefault();
setIsLoading(true);
// Simulate API call
await new Promise(resolve => setTimeout(resolve, 1500));
console.log('Login attempt:', { email, password });
setIsLoading(false);
};
return (

);
}
export default LoginForm;
Step 3: Integrate the Component
Update src/App.js to render your login form:
import React from 'react';
import LoginForm from './components/LoginForm';
function App() {
return <LoginForm />;
}
export default App;
Launch the development server:
npm start
