A wireframe is a simplified sketch of a website or app interface. It shows where each element appears, whether it’s headings, text, images, buttons, menus, or forms.
It may omit colors, actual images, and a fully developed design, consisting instead of boxes, lines, and placeholders. This conceptual phase focuses on layout, structure, and user navigation—not on visual design.
The wireframe answers fundamental questions: What elements does the page need? In what order do they appear? How does the visitor navigate the page?
