└── HoverCardContent
```

## Trigger Delays

Use `openDelay` and `closeDelay` on the `HoverCard` to control when the card opens and
closes.

```tsx showLineNumbers
<HoverCard openDelay={100} closeDelay={200}>
  <HoverCardTrigger>Hover</HoverCardTrigger>
  <HoverCardContent>Content</HoverCardContent>
</HoverCard>
```

## Positioning

Use the `side` and `align` props on `HoverCardContent` to control placement.

```tsx showLineNumbers
<HoverCard>
  <HoverCardTrigger>Hover</HoverCardTrigger>
  <HoverCardContent side="top" align="start">
    Content
  </HoverCardContent>
</HoverCard>
```
