What Tooltip & Popover Designer does and how it behaves

A tooltip is the small label that appears beside an element on hover or focus; a popover is the larger card that can carry links and buttons. This designer styles both: you choose which edge the arrow points from, pick a light or dark theme, and set the trigger behavior that shows and hides the bubble. Every change redraws the preview against a sample anchor, and the work stays in the browser - nothing is uploaded. The mistake most users make is treating hover as the only trigger: a hover-only bubble never appears for keyboard users, and a bubble separated from its anchor flickers as the pointer crosses the gap.

How the result is produced

Arrow placement

Placement picks the edge the arrow leaves from - top, bottom, left, or right - and the preview redraws the bubble on that side of the anchor. Placement depends on a positioned anchor: a bubble offset a few pixels from its anchor only lands where the preview shows it if the anchor establishes a positioning context, which is one line of CSS on the wrapper.

Themes and triggers

Themes restyle the bubble as one unit - background, text, border, and arrow color move together in light and dark variants. Trigger behavior decides what reveals the bubble and what hides it: hover, click, or focus, and a click-triggered popover also needs a dismissal path, usually an outside click or the Escape key. Pair the trigger with the content: text-only labels suit hover, anything clickable inside belongs on click.

Good uses

Give a data table or dashboard chart a styled tooltip that matches the site theme instead of the browser's default title-attribute bubble.
Design a help popover for a form field or icon that opens on click and can hold a documentation link.
Spec a consistent set of variants - four placements in light and dark - to hand to a design system or component library.

Limits and checks

Hover gap: with hover as the trigger, any space between the anchor and the bubble makes the pointer cross empty territory, and the bubble disappears before the user can reach it. Keep the bubble touching the anchor or widen the effective trigger zone.
Keyboard reach: hover is a pointer-only interaction, so a hover-only design never appears for keyboard users. Per the WAI-ARIA tooltip pattern, tooltip content must be non-interactive - links and buttons belong in a popover, not a tooltip - so check what the result does on focus.
Positioning context: the preview places the bubble against its anchor, and the result behaves the same on your page only when the anchor establishes a positioning context. Without it, the bubble lands at the document's top-left corner instead of beside the element.

Common questions

Why does my hover tooltip vanish when I move the pointer toward it?

Because the pointer has left the trigger: with hover as the trigger, the bubble hides the moment the trigger loses the pointer, and the gap between anchor and bubble kills it before you can enter it. Attach the bubble to the anchor, widen the trigger zone, or switch to a click trigger - the right fix when the bubble contains anything interactive.

What is the difference between a tooltip and a popover in this tool?

A tooltip is a short, text-only label shown on hover or focus; a popover is a larger card that may hold links, buttons, or a form, opens on click, and dismisses on outside click or Escape. The WAI-ARIA tooltip pattern says interactive content does not belong inside a tooltip, so use the popover side of the designer for anything clickable.
