Screenshot; an image taken by a person to record visible items displayed on a screen. This is an action that most developers are familiar because it conveys a lot of visual information that text cannot.

On the desktop, we commonly use browsers apps or widgets to capture elements of a website and this can become tedious overtime. Some of these apps only allow the user to capture what is on their screen instead of the entire page.
