Layout is broken, cut off or overlapping
Layout problems come from your site’s CSS interacting with the widget.
Widget not showing on Wix
On Wix the widget usually does show — it is cut off.
The short answer
On Wix the widget usually does show — it is cut off. Wix puts embeds in a fixed-size iframe that does not scroll, so anything taller than the element is clipped.
Drag the element taller. That solves most Wix reports.
Cut off at the bottom
The Embed HTML element has a fixed height and the widget does not make it grow. Drag the element until the whole widget fits, and check on mobile separately, where the widget is taller.
Not appearing at all
Not published — Wix requires publishing; the editor preview is not the live site. Wrong element — use Embed HTML, not a text element. Custom Code not saved — for site-wide placement check Settings → Custom Code and that it applies to the pages you expect.
Mobile
Wix keeps a separate mobile layout. An element sized correctly on desktop can still be clipped on mobile, and it needs adjusting in the mobile editor.
