CSS3 Rotate Animation: Resolving CSS Issues for Image Rotation
CSS3 animations provide a powerful tool for creating dynamic and visually engaging web experiences. One common use case is rotating an image or element using the transform property. However, incorrect CSS can prevent the animation from functioning correctly.
An example of such an issue is provided, where an image is intended to rotate 360 degrees but remains static. The problem lies within the provided CSS.
The Correct CSS
To fix the issue, the following revised CSS has been created:
.image {</p> <pre class="brush:php;toolbar:false">position: absolute; top: 50%; left: 50%; width: 120px; height: 120px; margin:-60px 0 0 -60px; -webkit-animation:spin 4s linear infinite; -moz-animation:spin 4s linear infinite; animation:spin 4s linear infinite;
}
@-moz-keyframes spin {
100% { -moz-transform: rotate(360deg); }
}
@-webkit-keyframes spin {
100% { -webkit-transform: rotate(360deg); }
}
@keyframes spin {
100% { -webkit-transform: rotate(360deg); transform:rotate(360deg); }
}
The key difference lies in the margin property and the removal of the from and to states from the animation keyframes.
Explanation
The margin property correctly positions the image in the center of the page. The transform property, which applies the rotation, is set for all frames in the animation using the 100% state. By removing the from and to states, the animation becomes smoother, avoiding an abrupt transition at the beginning and end of the rotation.
With these changes implemented, the animated image should now rotate smoothly and continuously.

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.

Advanced usage: Use nested counters to create complex numbers, such as chapter and section numbers. 3.
