API Reference

Root

Contains all the parts of a hover card.

Trigger

The link that opens the hover card when hovered.

PropTypeDefault
asChildbooleanfalse
Data attributeValues
[data-state]"open" | "closed"

Portal

When used, portals the content part into the body.

PropTypeDefault
forceMountboolean—
containerHTMLElementdocument.body

Content

The component that pops out when the hover card is open.

PropTypeDefault
asChildbooleanfalse

CSS VariableDescription
--radix-hover-card-content-transform-originThe transform-origin computed from the content and arrow positions/offsets
--radix-hover-card-content-available-widthThe remaining width between the trigger and the boundary edge
--radix-hover-card-content-available-heightThe remaining height between the trigger and the boundary edge
--radix-hover-card-trigger-widthThe width of the trigger
--radix-hover-card-trigger-heightThe height of the trigger

Arrow

An optional arrow element to render alongside the hover card. This can be used to help visually link the trigger with the HoverCard.Content. Must be rendered inside HoverCard.Content.

PropTypeDefault
asChildbooleanfalse
widthnumber10
heightnumber5

Examples

Show instantly

Use the openDelay prop to control the time it takes for the hover card to open.

import { HoverCard } from "@radix-solid/primitives";
export default () => <HoverCard.Root openDelay={0}>
<HoverCard.Trigger>…</HoverCard.Trigger>
<HoverCard.Content>…</HoverCard.Content>
</HoverCard.Root>;

Constrain the content size

You may want to constrain the width of the content so that it matches the trigger width. You may also want to constrain its height to not exceed the viewport.

We expose several CSS custom properties such as --radix-hover-card-trigger-width and --radix-hover-card-content-available-height to support this. Use them to constrain the content dimensions.

// index.tsx
import { HoverCard } from "@radix-solid/primitives";
import "./styles.css";
export default () => <HoverCard.Root>
<HoverCard.Trigger>…</HoverCard.Trigger>
<HoverCard.Portal>
<HoverCard.Content class="HoverCardContent" sideOffset={5}>
…
</HoverCard.Content>
</HoverCard.Portal>
</HoverCard.Root>;
/* styles.css */
.HoverCardContent {
width: var(--radix-hover-card-trigger-width);
max-height: var(--radix-hover-card-content-available-height);
}

Origin-aware animations

We expose a CSS custom property --radix-hover-card-content-transform-origin. Use it to animate the content from its computed origin based on side, sideOffset, align, alignOffset and any collisions.

// index.tsx
import { HoverCard } from "@radix-solid/primitives";
import "./styles.css";
export default () => <HoverCard.Root>
<HoverCard.Trigger>…</HoverCard.Trigger>
<HoverCard.Content class="HoverCardContent">…</HoverCard.Content>
</HoverCard.Root>;
/* styles.css */
.HoverCardContent {
transform-origin: var(--radix-hover-card-content-transform-origin);
animation: scaleIn 0.5s ease-out;
}
@keyframes scaleIn {
from {
opacity: 0;
transform: scale(0);
}
to {
opacity: 1;
transform: scale(1);
}
}

Collision-aware animations

We expose data-side and data-align attributes. Their values will change at runtime to reflect collisions. Use them to create collision and direction-aware animations.

// index.tsx
import { HoverCard } from "@radix-solid/primitives";
import "./styles.css";
export default () => <HoverCard.Root>
<HoverCard.Trigger>…</HoverCard.Trigger>
<HoverCard.Content class="HoverCardContent">…</HoverCard.Content>
</HoverCard.Root>;
/* styles.css */
.HoverCardContent {
animation-duration: 0.6s;
animation-timing-function: cubic-bezier(0.16, 1, 0.3, 1);
}
.HoverCardContent[data-side="top"] {
animation-name: slideUp;
}
.HoverCardContent[data-side="bottom"] {
animation-name: slideDown;
}
@keyframes slideUp {
from {
opacity: 0;
transform: translateY(10px);
}
to {
opacity: 1;
transform: translateY(0);
}
}
@keyframes slideDown {
from {
opacity: 0;
transform: translateY(-10px);
}
to {
opacity: 1;
transform: translateY(0);
}
}

Accessibility

The hover card is intended for sighted users only, the content will be inaccessible to keyboard users.
