Web development is the process of creating and building websites or web applications for the internet. It involves a variety of tasks such as designing, coding, testing, and maintaining websites.
Web development can be divided into two categories: front-end development and back-end development. Front-end development is the part of web development that deals with the user interface and user experience of a website. It involves designing and coding the visible elements of a website, such as layouts, colors, fonts, and interactive features.
Back-end development is the part of web development that deals with the server-side of a website. It involves creating and managing the database, server-side scripting, and other technical aspects of a website that are not visible to the user.
Web development can be done using a variety of programming languages and frameworks such as HTML, CSS, JavaScript, PHP, Python, and Ruby on Rails. The choice of programming language and framework depends on the requirements of the project and the expertise of the developer.
