内容大小动画

¥Animating content size

使用 --radix-collapsible-content-width 和/或 --radix-collapsible-content-height CSS 变量为内容打开/关闭时的大小设置动画。这是一个演示：

¥Use the --radix-collapsible-content-width and/or --radix-collapsible-content-height CSS variables to animate the size of the content when it opens/closes. Here's a demo:

// index.jsx
import { Collapsible } from "radix-ui";
import "./styles.css";

export default () => (
	<Collapsible.Root>
		<Collapsible.Trigger>…</Collapsible.Trigger>
		<Collapsible.Content className="CollapsibleContent">
			…
		</Collapsible.Content>
	</Collapsible.Root>
);

/* styles.css */
.CollapsibleContent {
	overflow: hidden;
}
.CollapsibleContent[data-state="open"] {
	animation: slideDown 300ms ease-out;
}
.CollapsibleContent[data-state="closed"] {
	animation: slideUp 300ms ease-out;
}

@keyframes slideDown {
	from {
		height: 0;
	}
	to {
		height: var(--radix-collapsible-content-height);
	}
}

@keyframes slideUp {
	from {
		height: var(--radix-collapsible-content-height);
	}
	to {
		height: 0;
	}
}
