Frontend

Frontend, also written as “front end,” is the part of a website, application, or online store that users see and interact with directly. It includes page layouts, navigation, buttons, forms, images, animations, and the way the interface adapts to different devices.

Frontend development primarily uses HTML, CSS, and JavaScript. HTML defines the content structure, CSS controls its appearance and layout, and JavaScript adds interactions and dynamic behavior. An interface can be developed from scratch or generated by a content management system such as WordPress.

How does the frontend work?

When someone visits a website, the browser downloads the necessary files and renders them as a visible interface. The frontend can also communicate with a server to retrieve products, submit a form, sign in a user, or update a shopping cart without reloading the entire page.

A well-developed frontend should be clear, responsive, fast, and accessible to people using different devices and assistive technologies. It should also work correctly across major web browsers.

What is the difference between frontend and backend?

The frontend is the part of a system presented to the user. The backend operates on the server and handles areas such as business logic, databases, user accounts, permissions, and data processing.

The two layers work together. The frontend sends information provided by the user, the backend validates and processes it, and the result is returned to the interface.

What does a frontend developer do?

A frontend developer turns a visual design into a working website or application. Their work includes building the structure and interactions, adapting the interface to different screen sizes, improving performance and accessibility, and connecting the frontend to the backend.

Frontend development is therefore not limited to a website’s appearance. It also determines how individual elements behave and shapes the overall user experience.
