动画
为 HeroUI v3 组件添加流畅的动画和过渡
HeroUI 组件支持多种动画方法:内置 CSS 过渡、自定义 CSS 动画以及 Framer Motion 等 JavaScript 库。
内置动画
HeroUI 组件使用数据属性来公开其动画状态:
/* Popover entrance/exit */
.popover[data-entering] {
@apply animate-in zoom-in-90 fade-in-0 duration-200;
}
.popover[data-exiting] {
@apply animate-out zoom-out-95 fade-out duration-150;
}
/* Button press effect */
.button:active,
.button[data-pressed="true"] {
transform: scale(0.97);
}
/* Accordion expansion */
.accordion__panel[aria-hidden="false"] {
@apply h-[var(--panel-height)] opacity-100;
}状态样式属性:
[data-hovered="true"]- 悬停状态[data-pressed="true"]- 活动/按下状态[data-focus-visible="true"]- 键盘焦点[data-disabled="true"]- 禁用状态[data-entering]/[data-exiting]- 过渡状态[aria-expanded="true"]- 展开状态
CSS 动画
使用 Tailwind 实用程序:
// Pulse on hover
<Button className="hover:animate-pulse">
Hover me
</Button>
// Fade in entrance
<Alert className="animate-fade-in">
Welcome message
</Alert>
// Staggered list
<div className="space-y-2">
<Card className="animate-fade-in animate-delay-100">Item 1</Card>
<Card className="animate-fade-in animate-delay-200">Item 2</Card>
</div>自定义过渡:
/* Slower accordion */
.accordion__panel {
@apply transition-all duration-500;
}
/* Bouncy button */
.button:active {
animation: bounce 0.3s;
}
@keyframes bounce {
50% { transform: scale(0.95); }
}Framer Motion
HeroUI 组件与 Framer Motion 无缝协作,实现高级动画。
基本用法:
import { motion } from 'framer-motion';
import { Button } from '@heroui/react';
const MotionButton = motion(Button);
<MotionButton
whileHover={{ scale: 1.05 }}
whileTap={{ scale: 0.95 }}
>
Animated Button
</MotionButton>入口动画:
<motion.div
initial={{ opacity: 0, y: 20 }}
animate={{ opacity: 1, y: 0 }}
transition={{ duration: 0.5 }}
>
<Alert>
<Alert.Title>Welcome!</Alert.Title>
</Alert>
</motion.div>布局动画:
import { AnimatePresence, motion } from 'framer-motion';
function Tabs({ items, selected }) {
return (
<div className="flex gap-2">
{items.map((item, i) => (
<Button key={i} onPress={() => setSelected(i)}>
{item}
{selected === i && (
<motion.div
layoutId="active"
className="absolute inset-0 bg-accent"
transition={{ type: "spring", bounce: 0.2 }}
/>
)}
</Button>
))}
</div>
);
}渲染属性
根据组件状态应用动态动画:
<Button>
{({ isPressed, isHovered }) => (
<motion.span
animate={{
scale: isPressed ? 0.95 : isHovered ? 1.05 : 1
}}
>
Interactive Button
</motion.span>
)}
</Button>无障碍
尊重动态偏好: HeroUI 使用 Tailwind 的 motion-reduce 工具自动尊重用户动态效果偏好。当用户在系统设置中启用“减少动态效果”时,所有内置的过渡和动画效果都将被禁用。
HeroUI 扩展了 Tailwind 的 motion-reduce: 变体,以同时支持原生 prefers-reduced-motion 媒体查询和 data-reduce-motion 属性。
/* HeroUI pattern - uses Tailwind's motion-reduce: */
.button {
@apply transition-colors motion-reduce:transition-none;
}
/* Expands to support both approaches: */
@media (prefers-reduced-motion: reduce) {
.button {
transition: none;
}
}
[data-reduce-motion="true"] .button {
transition: none;
}使用Framer Motion:
import { useReducedMotion } from 'framer-motion';
function AnimatedCard() {
const shouldReduceMotion = useReducedMotion();
return (
<motion.div
initial={{ opacity: 0 }}
animate={{ opacity: 1 }}
transition={{ duration: shouldReduceMotion ? 0 : 0.5 }}
>
<Card>Content</Card>
</motion.div>
);
}全局禁用动画: 添加data-reduce-motion="true"到<html>或者<body>标签:
<html data-reduce-motion="true">
<!-- All HeroUI animations will be disabled -->
</html>HeroUI自动检测用户的prefers-reduced-motion: reduce相应地设置并禁用动画。
性能技巧
使用 GPU 加速属性: 首选transform和opacity对于流畅的动画:
/* Good - GPU accelerated */
.slide-in {
transform: translateX(-100%);
transition: transform 0.3s;
}
/* Avoid - Triggers layout */
.slide-in {
left: -100%;
transition: left 0.3s;
}will-change优化: 使用will-change优化动画,但在不设置动画时将其删除:
.button {
will-change: transform;
}
.button:not(:hover) {
will-change: auto;
}
