The process of planning, building, and maintaining a website is known as web development. Usually, a web developer will take an idea that someone else has had and make it a reality. This could entail developing the design ideas, creating the site's framework, coding the features using HTML, CSS, and JavaScript (also known as "web languages"), testing the site to ensure that it works properly, and adding any required graphics or photos.

Front-end developers (those who work on the graphical user interface) and back-end developers are the two main kinds of web developers (those who deal with server side scripting). Due to their responsibility for creating the user interfaces for websites, front-end developers often require less technical knowledge than back-end DJs. They could also be in charge of developing creative concepts for fresh designs or advertising strategies. On the other side, back end developers are more technically adept now.
