What is a floating action button in software development?

A floating action button (FAB) is a type of button that is used in software development. It is generally used to perform an action that is related to the primary task of the user. For example, a FAB could be used to add a new contact to a list or to create a new document. The floating action button is designed to be placed on top of other content so that it is easily accessible by the user. It is usually positioned in the bottom-right corner of the screen. The floating action button has become a popular feature in many mobile apps and web applications.
