Wireframe

A website wireframe is a visual guide that represents a website. There are different types of wireframes, from low-level to high-level wireframes. In software and design, wireframes are created for the purpose of arranging visual elements to describe how a website will look or explain the developers or stakeholders the different components in a website. Wireframes are also created to explain the designers the different components that are part of a website before the designer can start working on the high-level design of the page.

In PowerPoint, you can design a wireframe by arranging components and shapes in the presentation slide.
