Hover Card

A floating preview that opens on hover — profile peeks, link previews, glossary terms — with the neobrutalist borders-and-shadows treatment.

import {
  Avatar,
  AvatarFallback,

The hover card floats a panel of rich preview content over the page when the pointer rests on a trigger — no click required. Built on the Base UI Preview Card primitive and styled to the neobrutalist recipe: thick borders, hard shadows, and bold type.

Reach for it when:

Profile peeks — hover a @mention or avatar to show the bio, stats, and a follow button.
Link previews — surface a page's title and summary before the reader commits to the click.
Glossary terms — define jargon inline in docs without navigating away.

Usage

import {
  HoverCard,
  HoverCardContent,
  HoverCardTrigger,
} from "@/components/ui/hover-card"

<HoverCard>
  <HoverCardTrigger>Hover</HoverCardTrigger>
  <HoverCardContent>
    The React Framework – created and maintained by @vercel.
  </HoverCardContent>
</HoverCard>

Composition

Use the following composition to build a HoverCard:

HoverCard
├── HoverCardTrigger
└── HoverCardContent

Trigger Delays

Use delay and closeDelay on the trigger to control when the card opens and closes.

<HoverCard>
  <HoverCardTrigger delay={100} closeDelay={200}>
    Hover
  </HoverCardTrigger>
  <HoverCardContent>Content</HoverCardContent>
</HoverCard>

Positioning

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

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

Accessibility

Hover cards have no dedicated WAI-ARIA pattern — the closest analogue is the Tooltip pattern. The Base UI primitive opens the card on keyboard focus of the trigger and dismisses it with Escape. Still, treat the content as supplemental for sighted users and keep the trigger a real link so the full content stays reachable at its destination.

Keyboard interactions:

Key	Action
`Tab` / `Shift + Tab`	Move focus to the trigger — focusing opens the card, leaving closes it
`Escape`	Close the card
`Enter`	Follow the trigger link
