CSS transitions are a way to define parameters for animating changes
to CSS properties on a specified element. Changes to styles can occur
because of updates in element state ( :hover , :valid , and so on), scripted
changes to styles on an element, or other scripted changes to the DOM
structure causing a change in how selectors are applied.
transition-property designates which CSS property or properties are
animated when a change occurs. Animations can occur with most CSS
properties; however, some properties such as background-image and
■ none : No properties will be animated (default).
■ all : All properties that can be animated will be.
■ <property-name>[, <property-name>] : A comma-separated list of
one or more properties that can be animated if a change occurs.
