+# usePositionStickyObserver
+
+This composition is abstracts away the logic necessary to determine if a `position: sticky;` element has gone into it's "stuck" mode. This is useful when you want to style the element differently when it's stuck, like if you want to add a background color.
+
+## Example
+
+```typescript
+const stickyHeader = ref<HTMLElement>()
+const { stuck } = usePositionStickyObserver(stickyHeader)
+
+const classes = computed(() ({
+  header: {
+    'header--stuck': stuck.value,
+  }
+}))
+```
+
+## Arguments
+
+| Name    | Type                                           |
+| ------- | ---------------------------------------------- |
+| element | `HTMLElement \| Ref<HTMLElement \| undefined>` |
+| options | '{}'                                           |
+
+### Options
+
+| Name            | Type                                                                                                   |
+| --------------- | ------------------------------------------------------------------------------------------------------ |
+| rootMargin      | `string`, [MDN DOcs](https://developer.mozilla.org/en-US/docs/Web/API/IntersectionObserver/rootMargin) |
+| boundingElement | `HTMLElement \| Ref<HTMLElement \| undefined>`. The scroll container, defaults to the body.            |
+
+## Returns
+
+`UsePositionStickyObserverResponse`
