HTML5 CSS JavaScript

The standard triad for building high-performance, responsive, and interactive web applications.

This core stack powers over 98 percent of the web. HTML5 provides the semantic structure through elements like <main> and <section>. CSS3 handles the visual layer using layout engines like Flexbox and Grid for responsive design. JavaScript (ES6+) drives the logic, enabling dynamic DOM manipulation and asynchronous data fetching. Together, these technologies allow developers to build cross-platform tools that run natively in any modern browser (Chrome, Safari, Firefox) without third-party plugins.
