The term front – end defines itself; the interface that interacts with the client-side browser, including content delivery, style guide, graphs/tables, typography or font, buttons, and the navigation menu. An individual who writes code of front end languages is known as a frontend dev or developer. The work of the front end is to create a responsive web layout that is appealing by nature but also has reduced page load time. Most of all front-end architecture includes HTML, CSS, and javascript. When it comes to front end practice, these three programming languages set the core of the basic structure, design system, and how the front end components will respond on tap, which is the back-end term.
