title: Popover Previews
---

Like Wikipedia, when you hover over a link in Quartz, there is a popup of a page preview that you can scroll to see the entire content.

By default, Quartz only fetches previews for pages inside your vault due to [CORS](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS). It does this by selecting all HTML elements with the `popover-hint` class. For most pages, this includes the page title, page metadata like words and time to read, tags, and the actual page content.

When [[creating components|creating your own components]], you can include this `popover-hint` class to also include it in the popover.

## Configuration

- Remove popovers: set the `enablePopovers` field in `quartz.config.ts` to be `false`.
- Style: `quartz/components/styles/popover.scss`
- Script: `quartz/components/scripts/popover.inline.ts`
