Background Animation with CSS3
When implementing animations with CSS3, one may encounter challenges like the lack of response in changing background images. To resolve this issue, it's crucial to understand the proper syntax and techniques.
The code provided involves defining an animation named "test" using the @-webkit-keyframes rule, which specifies the background images at various stages of the animation. However, the problem lies in how the animation property is being applied to the div element.
Updated Solution
The updated solution demonstrates how to correctly animate background image changes using the animation property. The updated CSS code below:
#mydiv {
animation: changeBg 1s infinite;
width: 143px;
height: 100px;
}
@keyframes changeBg {
0%, 100% {
background-image: url("https://i.sstatic.net/YdrqG.png");
}
25% {
background-image: url("https://i.sstatic.net/2wKWi.png");
}
50% {
background-image: url("https://i.sstatic.net/HobHO.png");
}
75% {
background-image: url("https://i.sstatic.net/3hiHO.png");
}
}
Key Differences in Approach
- Animation Property: Instead of using the prefixed -webkit-animation-name property, the updated code uses the modern animation property for cross-browser compatibility.
- Animation Duration and Iteration Count: The updated code sets the animation-duration to 1 second and animation-iteration-count to infinite to ensure seamless looping of the animation.
- Background Image URLs: The code includes specific URLs for each background image.
- Element ID: The updated code introduces an ID of "mydiv" for the target element to ensure specific styling and animation.
By implementing these changes, the background image should now animate as desired. This solution aligns with modern browser standards and provides a more consistent and reliable animation experience.

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.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
