Web design is the design of sites that are found on the internet. It typically refers to the consumer experience in web development. Good web design is responsive, meaning that it should look beautiful across all devices, such as mobile phones, desktops or tablets. It should also be simple, with good structure and categorization.
Web development, on the other hand, refers to the coding or programming of web pages. Web development, just like software outsourcing and development, should have good code quality, should be scalable, secure and should have high performance.
