Background Images in Keyframes: Display Issues in Firefox and Internet Explorer

Background animations are a crucial aspect of web design, allowing websites to add visual depth and interactivity. However, users have reported issues with background images not displaying in keyframes, specifically in Firefox and Internet Explorer.

To understand this behavior, it's important to consider the specifications outlined for CSS background properties. According to the specs, background-image is not an animatable property. Consequently, browsers handle this scenario unpredictably.

While Chrome (Webkit) displays the background image in keyframes, Firefox and IE disregard it altogether. This discrepancy stems from the ambiguous nature of the specifications, which fail to provide clear guidance on the handling of background-image in animation contexts.

In Firefox, there is a subtle inconsistency. When transitioning background-image, the second image appears immediately upon hovering an element. However, during animation, the second image remains hidden.

To address this issue, it's recommended to avoid setting background-image within keyframes. Instead, consider utilizing background-position or opacity to manipulate visual effects. By adhering to this approach, you can ensure consistent behavior across different browsers.
