Creating a website's user interface so that users may interact with it. Front-end developers used HTML, CSS, and JS to construct this interface.
To speed up the development process, front-end developers can employ style preprocessors, javascript libraries, and frameworks.
Back-end developers use the markup provided by front-end developers to create a dynamic website and send all essential data to the server and databases.
PHP and MySQL are used by back-end developers to build the website's backbone.
The same integrated web design development environments may be used by front-end and back-end developers (IDEs). These are programs that allow you to design and create the framework for a website.
