How to Implement Reverse Animation on Mouse Out after Hover
In web design, animations play a crucial role in enhancing user experience. One common scenario is hovering an element to trigger an animation, typically a rotation. However, reversing the animation on mouse out can prove challenging, especially when using CSS3's @keyframes.
Considering the provided CSS example, where on hover the element rotates 360 degrees, the goal is to have it rotate back to 0 degrees on mouse out. Using @keyframes animation, it appears the desired effect cannot be achieved.
The solution lies in understanding the animation-direction property. "To" represents the end state of the animation, while "from" specifies the starting state. By incorporating the "from" keyword in our @keyframes definitions, we can create the reverse animation:
@keyframes in {
from: transform: rotate(0deg);
to: transform: rotate(360deg);
}
@keyframes out {
from: transform: rotate(360deg);
to: transform: rotate(0deg);
}
Additionally, cross-browser compatibility can be ensured by using vendor prefixes:
@-webkit-keyframes in {
...
}
@-webkit-keyframes out {
...
}
To further enhance the animation, it's crucial to specify the animation-direction property:
.class {
animation-direction: alternate;
}
This way, the animation will seamlessly transition from "in" to "out" when the mouse moves out of the element's boundary.
Implementing this approach results in a smooth and efficient reverse animation that responds to mouse movements precisely. Here's a demonstration:

How can I include CSS only on some pages?
Jun 11, 2025 am 12:01 AM
There are three ways to selectively include CSS on a specific page: 1. Inline CSS, suitable for pages that are not frequently accessed or require unique styles; 2. Load external CSS files using JavaScript conditions, suitable for situations where flexibility is required; 3. Containment on the server side, suitable for scenarios using server-side languages. This approach can optimize website performance and maintainability, but requires balance of modularity and performance.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.
