Optimizing CSS time-based animations with new CSS functions

The introduction of new CSS functions like mod(), round(), and trigonometric functions has significantly enhanced the ability to create time-based animations in CSS, which were previously limited by the rigidity of traditional keyframes. These functions allow for dynamic, flexible animations by using mathematical calculations to create smooth transitions, altering properties like position, size, and color over time. This advancement offers developers greater control and performance efficiency, as these animations are less CPU-intensive and more GPU-friendly compared to JavaScript-based alternatives. While CSS functions excel in simplicity and reusability, their compatibility is not universal across all browsers, unlike JavaScript or keyframe animations. The article also highlights the importance of understanding CSS animations and transitions, as well as basic JavaScript, to fully explore the potential of these new CSS functions.
