The Presentation Layer: Frontend

This is where the magic happens for the user. Learn how HTML, CSS, and JavaScript collaborate to build beautiful, responsive applications right inside your browser.

The Client-Side Experience

The Frontend (or client-side) is everything you can see, click, and interact with. It runs entirely within your browser, which is why we call it the Presentation Layer. It's responsible for fetching data from the backend, interpreting it, and drawing the interface.

Key Goals of the Frontend

Responsiveness: Ensuring the layout looks and functions correctly across all screen sizes (phones, tablets, desktops).
Accessibility: Making sure the interface is usable by everyone, including people using assistive technologies (like screen readers).
Interactivity: Providing immediate feedback and dynamic elements without needing to reload the entire page.
