Here is the brief explanation on how to specify the name of the CSS property for the transition effect using the CSS3 Transition-Property property.
Where, none - No property will get a transition effect
all - Default value. All properties will get a transition effect
property - Defines a comma separated list of CSS property names the transition effect is for
initial - Sets this property to its default value.
inherit - Inherits this property from its parent element.
transition-property: width, height;
The transition-property specifies the name of the CSS property the transition effect is for. A transition effect could typically occur when a user hover over an element. Always specify the transition-duration property, otherwise the duration is 0, and the transition will have no effect.
