There's a way to prevent the return to the original CSS style after an animation?

Question

What I need to do is something like an auto-start transition. But the transitions can't start automatically, so I thought to utilize an animation that not return to the original CSS style of an element after the end of the animation.

Answer 1

animation-fill-mode: forwards is what you're looking for. This makes the element keep the values from the last keyframe of the animation.
