Tooltip
A popup that displays information related to an element when hovered or focused, built on the Base UI Tooltip primitive.
Installation
Bash
Usage
Accessibility
Base UI treats tooltips as supplementary visual labels: the popup carries
no role="tooltip" or aria-describedby wiring by design. Screen reader
users hear the trigger’s accessible name instead — so whenever the
trigger’s visible content doesn’t match the tooltip (icon buttons,
“Hover me” style triggers), give the trigger an aria-label that mirrors
the tooltip text.
API reference
Tooltips are intentionally disabled on touch devices (Base UI behavior —
there’s no hover to trigger them); for info icons that need to work on
touch, use a Popover with openOnHover
instead.
TooltipProvider
Shares open/close delays across every tooltip it wraps — once one
tooltip has opened, moving to another within the timeout window opens
the next one instantly, skipping its own delay.
| Prop | Type | Default |
|---|---|---|
timeout | number | 400 (ms) |
TooltipTrigger
Extends the Base UI Tooltip
Trigger — delays live here (Base UI 1.7 moved them off the Root). Use
the render prop for the trigger element:
render={<Button variant="outline" />}.
| Prop | Type | Default |
|---|---|---|
delay | number | 600 (ms) |
closeDelay | number | 0 (ms) |
TooltipContent
| Prop | Type | Default |
|---|---|---|
side / align | positioner placement | "top" / "center" |
sideOffset | number | 8 |
side defaulting to top makes Tooltip the only overlay in the
registry whose default isn’t bottom.
