openclaw skills install fec-svg-animationUse when implementing or reviewing SVG animation, path drawing, icon motion, logo animation, illustration motion, micro-interactions, CSS/SMIL/Framer Motion/GSAP choices, motion accessibility, or fallback behavior; Chinese triggers include SVG 动画, 路径描边, 动效.
openclaw skills install fec-svg-animation为 SVG 图标、插画和数据可视化提供可维护、可访问、性能可控的动画方案。
prefers-reduced-motion 提供动效降级。按复杂度和运行时需求选型:
| 场景 | 推荐 |
|---|---|
| hover/focus、opacity、transform | CSS animation/transition |
| 路径描边、简单重复动效 | CSS + stroke-dasharray |
| React 组件状态驱动动画 | Framer Motion |
| 时间轴、复杂编排、滚动触发 | GSAP |
| 需要保持零依赖的静态 SVG | CSS 或 SMIL |
如果动效跨越页面转场、滚动叙事或复杂组件编排,应先按交互动效 workflow 判断强度、懒加载和 reduced-motion 策略;本 skill 只负责 SVG 图形本身的路径、形变和图标 motion。

transform、opacity 和 SVG 路径属性;避免高频修改 layout 相关属性。aria-hidden="true"。prefers-reduced-motion,复杂动效必须提供静态或弱动效降级。产出一个可复用的 SVG 动画组件或样式方案,包含选型理由、动效降级和可访问性处理。验证时检查动画流畅、无布局抖动、键盘与 reduced-motion 场景可用。
