现在专注于移动端开发项目,对于动画这个点是非常重要的,每当我遇到一个新的知识点,我就会和大家一起分享
animation-fill-mode :把物体动画地从一个地方移动到另一个地方,并让它停留在那里
定义和用法
animation-fill-mode 属性规定当动画不播放时(当动画完成时,或当动画有一个延迟未开始播放时),要应用到元素的样式。
默认情况下,CSS 动画在第一个关键帧播放完之前不会影响元素,在最后一个关键帧完成后停止影响元素。animation-fill-mode 属性可重写该行为。

CSS-in-JS enhances style management flexibility but may increase file size. CSSHoudini allows direct operation of CSS rendering. 3.WebAssembly optimizes browser application performance but has a steep learning curve, and Serverless simplifies development but requires optimization of cold start problems.
