Zoom in zoom out animation css Code Snippet in 2025

Creates a zoom in zoom out animation.

• Use @keyframes to define a three-step animation. At the start (0%) and end (100%), the element is its original size (scale(1 ,1)). Halfway through (50%) it's scaled up to 1.5 times its original size (scale(1.5, 1.5)).
• Use width and height to give the element a specific size.
• Use animation to set the appropriate values for the element to make it animated.
