Unit 1 Introduction To Web Development

Web development encompasses creating, building, and maintaining websites, including web design, publishing, programming, and database management.

HTML's main purpose is to structure the front end of web pages using a markup language.

Frontend development involves the parts of a website that users interact with directly, while backend development handles the server-side functions that users do not see.
