Performance Overhead: One of the primary concerns with CSS animations is the potential performance overhead they might introduce. Complex animations can be resource-intensive, leading to sluggish performance, especially on lower-end devices or browsers. To mitigate this, it's crucial to optimize animations by limiting the number of animated properties and focusing on properties that require less processing power, such as opacity and transform. These properties can be handled by the device's GPU, offering smoother animations without severely impacting performance.
Cross-Browser Compatibility: Another significant challenge is ensuring that animations perform consistently across different browsers and versions. While CSS animations are widely supported, discrepancies in implementation can lead to inconsistent user experiences. To address...
