What is a wireframe?

Wireframes are schematic representations of the structure of a website or app that serve as the basic framework of the design. They show the layout of the page, the placement of elements and the navigation, without going into details such as colours or typefaces. Wireframes help to put the focus on functionality and user guidance before visual aspects are designed. They are an important tool for agreeing the foundations of a project and ensuring that the design meets users' requirements.
