Web design and development is the process of creating a website. It involves two major skill sets: web design and web development. Web design determines the look and feel of a website, while web development determines how it functions.

Web designers use programs like Adobe Photoshop and Illustrator to create the visual elements of a website, such as the layout, typography, and images. They also work with clients to understand their needs and goals for the website, and to create a design that meets those needs.

Web developers use programming languages like HTML, CSS, and JavaScript to create the functional aspects of a website. They code the pages so that they can be displayed correctly in web browsers, and they add features like navigation, forms, and e-commerce functionality.
