How Can I Reverse CSS Keyframe Animations Smoothly on Mouse Out?

Animation Reversal on Mouse Out: Addressing the Challenge

In the realm of web animation, achieving a smooth animation reversal on mouse out can be a tricky endeavor, especially when employing keyframe animations. Let's explore the original question and its solution, delving into the intricacies of CSS keyframes for an optimal outcome.

The Problem

As outlined in the initial inquiry, attempting to create a mouse out animation that reverses the hover animation using keyframes has proven challenging. The code snippet demonstrates a basic transform rotation animation that works on hover but does not revert back to its original state on mouse out.

The Solution

The key to achieving the desired animation reversal lies in utilizing both the "from" and "to" properties within the keyframe declarations. By specifying the initial transform state ("from") in the "in" keyframe and the final transform state ("to") in the "out" keyframe, we effectively create a smooth transition between the two.

Optimal Implementation

To ensure cross-browser compatibility, it's essential to use the correct keyframe syntax for different browsers. Here's the updated CSS code that takes these considerations into account:

@-webkit-keyframes in {
  from: transform: rotate(0deg);
  to: transform: rotate(360deg);
}

@-moz-keyframes in {
  from: transform: rotate(0deg);
  to: transform: rotate(360deg);
}

@-o-keyframes in {
  from: transform: rotate(0deg);
  to: transform: rotate(360deg);
}

@keyframes in {
  from: transform: rotate(0deg);
  to: transform: rotate(360deg);
}

@-webkit-keyframes out {
  from: transform: rotate(360deg);
  to: transform: rotate(0deg);
}

@-moz-keyframes out {
  from: transform: rotate(360deg);
  to: transform: rotate(0deg);
}

@-o-keyframes out {
  from: transform: rotate(360deg);
  to: transform: rotate(0deg);
}

@keyframes out {
  from: transform: rotate(360deg);
  to: transform: rotate(0deg);
}

This code ensures that the animation will function correctly in major browsers, providing a seamless animation experience that transitions smoothly from the hover to the non-hover state.
