How to Correctly Animate Background Images with CSS3?

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

1. Animation Property: Instead of using the prefixed -webkit-animation-name property, the updated code uses the modern animation property for cross-browser compatibility.
2. 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.
3. Background Image URLs: The code includes specific URLs for each background image.
4. 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.
