CSS3 Transition
CSS3 Transition
In CSS3, we can change from one style to another in order to add a certain effect without using Flash animation or JavaScript.
How does it work?
CSS3 Transition is the effect of an element gradually changing from one style to another.
To achieve this, two things must be specified:
Specify the CSS property to add the effect and specify the duration of the effect.
