+title: Tooltip
+---
+
+A tooltip's target is its _first child element_, so you should only wrap one element inside of the tooltip. If you need the tooltip to show up for multiple elements, nest them inside a container first.
+
+Tooltips use `display: contents` so they won't interfere with how elements are positioned in a flex or grid layout.
+
+<ha-tooltip content="This is a tooltip">
+  <ha-button>Hover Me</ha-button>
+</ha-tooltip>
+
+```
+<ha-tooltip content="This is a tooltip">
+  <ha-button>Hover Me</ha-button>
+</ha-tooltip>
+```
+
+## Documentation
+
+This element is based on sholace `sl-tooltip` it only sets some css tokens and has a custom show/hide animation.
+
+<a href="https://shoelace.style/components/tooltip" target="_blank" rel="noopener noreferrer">Shoelace documentation</a>

+### HA style tokens
+
+In your theme settings use this without the prefixed `--`.
