关键帧令牌：在项目中标准化动画

Animations can be one of the most joyful parts of building interfaces, but without structure, they can also become one of the biggest sources of frustration. By consolidating and standardizing keyframes, you take something that is usually messy and hard to manage and turn it into a clear, predictable system.

动画可以是构建界面中最愉快的部分之一，但如果没有结构，它们也可能成为最大来源的挫折。通过整合和标准化关键帧，您将通常混乱且难以管理的内容转变为一个清晰、可预测的系统。

Picture this: you join a new project, dive into the codebase, and within the first few hours, you discover something frustratingly familiar. Scattered throughout the stylesheets, you find multiple @keyframes definitions for the same basic animations. Three different fade-in effects, two or three slide variations, a handful of zoom animations, and at least two different spin animations because, well, why not?

想象一下：你加入一个新项目，深入代码库，在头几个小时内，你发现了一些令人沮丧的熟悉感。在样式表中，你发现多个相同基本动画的 @keyframes 定义。三种不同的淡入效果，两到三种滑动变体，一些缩放动画，以及至少两种不同的旋转动画，因为，嗯，为什么不呢？

@keyframes pulse { from { scale: 1; } to { scale: 1.1; }
} @keyframes bigger-pulse { 0%, 20%, 100% { scale: 1; } 10%, 40% { scale: 1.2; }
}

If this scenario sounds familiar, you’re not alone. In my experience across various projects, one of the most consistent quick wins I can deliver is consolidating and standardizing keyframes. It’s become such a reliable pattern that I now look forward to this cleanup as one of my first tasks on any new codebase.

如果这个场景听起来很熟悉，你并不孤单。在我参与的各种项目中，我能提供的最一致的快速胜利之一就是 整合和标准化关键帧。这已经成为一个如此可靠的模式，以至于我现在期待在任何新的代码库中将这项清理作为我的首要任务之一。

The Logic Behind The Chaos #

混乱背后的逻辑#

This redundancy makes perfect sense when you think about it. We all use the same fundamental animations in our day-to-day work: fades, slides, zooms, spins, and other common effects. These animations are pretty straightforward, and it’s easy to whip up a quick @keyframes definition to get the job done.

当你考虑这一点时，这种冗余是完全合理的。我们在日常工作中都使用相同的基本动画：渐变、滑动、缩放、旋转和其他常见效果。这些动画相当简单，快速编写一个 @keyframes 定义来完成工作也很容易。

Without a centralized animation system, developers naturally write these keyframes from scratch, unaware that simi...
