How Can I Control CSS3 Animation Behavior After Completion?

Controlling CSS3 Animation End Behavior

When creating engaging CSS3 animations, it's often necessary to control how they behave at their completion. One common requirement is to freeze an animation on its last frame.

Freezing Animation on Last Frame

The provided code demonstrates a four-part animation that concludes by taking the target element off the screen. However, it repeatedly returns to its original state after execution. To address this issue, we can utilize the animation-fill-mode property.

By setting this property to forwards, the animation will remain at its final state once it completes. The element will appear frozen on the last frame (100%) of the animation.

Alternatively, if you wish to remove the element from the page entirely after the animation, you can apply the following approach:

Here, animation_final_frame is the name of a CSS function that would be executed when the animation concludes. Within that function, you can add logic to remove the element from the DOM using JavaScript or jQuery.
