Web design and web development work together to create a successful website, but each serves a different purpose. Web design focuses on the visual presentation and user experience, including layouts, colours, typography, navigation and responsive elements. Web development brings those designs to life through coding, functionality, integrations and the technical systems that make a website operate. Understanding how these disciplines differ can help businesses plan projects, communicate with professionals and choose the right support for their requirements. This article explores the responsibilities of designers and developers, the skills each role involves and the areas where their work overlaps. It also explains why collaboration between both disciplines matters when creating a website that looks appealing, works reliably and supports business objectives. Whether you are planning a new website or improving an existing one, recognising the relationship between design and development can help you make more informed decisions.
