The landscape of front-end web development has evolved dramatically over the past decade. This paper explores the modern paradigms, features, and best practices of using HTML5, CSS3, and ECMAScript 6+ (ES6+) JavaScript. It covers semantic markup, responsive design with Flexbox and Grid, CSS custom properties, JavaScript modules, asynchronous programming, and the tooling ecosystem. The paper argues that mastery of these core technologies remains essential even with the rise of frameworks, providing the foundation for performant, accessible, and maintainable web applications. async function loadData() try const res = await

// Selecting Elements
const btn = document.querySelector('#submit-btn');
// Event Listener with Arrow Function

    e.preventDefault();
    console.log('Button clicked!');

async function fetchUserData() 
    try 
        const response = await fetch('https://api.example.com/users');
        const data = await response.json();
        console.log(data);
     catch (error) 
        console.error('Error fetching data:', error);
fetchUserData();

async function loadData()

   catch (error) 
    console.error(error);
