### AJAX content

Highslide's AJAX engine lets you put your content in a separate file and display it within a Highslide popup. If the file is HTML, you can specify a specific `id` for Highslide to fetch. In this case, the `id` intro was fetched.

To see the source of the linked AJAX file, right click on the anchor link that you clicked to open this popup, then choose Open in new window.

Highslide caches the AJAX content upon page load, so that it sits ready to display instantly when the user clicks the thumbnail or link.

### Dynamic content

Highslide HTML allows the popup size to be recalculated after the content has been changed, either through internal scripts or through external AJAX calls.

This example also has `hs.preserveContent` set to `true`. Try updating the content and move the popup, then close it and open it again.
