What’s the difference between website designing and website development?

Website design decides how a site looks and how users experience it (layout, colours, typography, user flow), while website development is the technical process of actually coding those designs into a functioning, interactive site using languages like HTML, CSS, and JavaScript. Design typically happens first, usually in a tool like Figma, producing static or interactive mockups that show exactly how each page should look and behave before a single line of production code is written.

Development then translates that visual design into working code, handling everything the design mockup can’t show, such as how the site connects to a database, processes form submissions, handles different screen sizes responsively, and loads efficiently. A designer and a developer often work iteratively together, since some design decisions (like a particular animation or layout) may need to be adjusted once a developer identifies technical constraints or performance costs.

Some professionals work across both disciplines (particularly on smaller projects), but larger website projects typically involve separate design and development specialists, since each requires a distinct and deep skill set.
