What is a wireframe?

A wireframe serves as a visual blueprint for a web page, capturing its layout and structure without the distractions of design elements such as colors and fonts. This conceptual tool allows designers and developers to focus on the arrangement of content, functionality, and user experience elements. By using a wireframe, stakeholders can visualize how users will interact with the website, ensuring the essential components are strategically placed for optimal usability.

In other contexts, the choices may represent different aspects of web design or project management, but they do not serve the specific purpose that a wireframe does. While aspects like color schemes and fonts (mentioned in the first choice) are significant in web design, they pertain more to the visual design phase, whereas wireframes deal with layout and functionality. Similarly, project timelines and milestones are critical for project management but do not provide the same visual representation as a wireframe. The mention of an interactive tutorial relates to educational resources rather than the structural planning involved in creating a web page. Thus, wireframes are distinct in their function, focusing primarily on the structural aspects of web design, making the identification of the correct answer clear.
