## CSS content-visibility for Long Lists
|
||
|
||
Apply `content-visibility: auto` to defer off-screen rendering.
|
||
|
||
**CSS:**
|
||
|
||
```css
|
||
.message-item {
|
||
content-visibility: auto;
|
||
contain-intrinsic-size: 0 80px;
|
||
}
|
||
```
|
||
|
||
**Example:**
|
||
|
||
```tsx
|
||
function MessageList({ messages }: { messages: Message[] }) {
|
||
return (
|
||
<div className="h-screen overflow-y-auto">
|
||
{messages.map((msg) => (
|
||
<div key={msg.id} className="message-item">
|
||
<Avatar user={msg.author} />
|
||
<div>{msg.content}</div>
|
||
</div>
|
||
))}
|
||
</div>
|
||
);
|
||
}
|
||
```
|
||
|
||
For 1000 messages, browser skips layout/paint for ~990 off-screen items (10× faster initial render).
