Wireframing is the practice of designing the structural layout and content hierarchy of an interface without introducing visual styling, colour, or brand elements. It represents the skeleton of a screen: where navigation lives, how content is prioritised, what interactive elements exist, and how the page flows. By separating structure from style, wireframing forces clear thinking about information architecture and user flow before visual design begins, which consistently produces better structural decisions than designing in full fidelity from the start.
