Introduction
Web programming is the process of creating interactive and dynamic websites on the internet. In this article, you will get acquainted with the basics of web programming and learn important concepts for beginners.
In web programming, there are basic languages such as HTML, CSS, and JavaScript. With these languages, it is possible to create web pages and control their appearance.
