Overlays

ITooltip ​

A short label for a control that cannot say what it does in the space it has. Opens on hover and on keyboard focus, so it is not mouse-only.

An icon-only trigger still needs its own aria-label: the tooltip adds to the name rather than supplying it.

Sides ​

The side is a preference: the tooltip flips when there is not enough room on that edge.

Alignment and offset ​

Arrow ​

Delay ​

delay is how long the pointer must rest before the tooltip opens, in milliseconds. Lower it for a toolbar the reader scans across; raise it where a passing hover should open nothing.

Rich content ​

Use the content slot when the tooltip needs markup. It closes as soon as the pointer leaves, so anything the reader has to interact with belongs in an IPopover or a dialog.

v-model:open controls it directly when you need to open one programmatically.

Slots ​

SlotWhen to use it
triggerThe element the tooltip describes. Required — there is no default slot
contentTooltip content with markup, instead of text

Tooltips do not open on touch, so keep anything essential readable without one.
