## Where it can go

- **Anywhere** on the page.
- **Out of place,** it stays in the page and does nothing: injected by Smootify, never placed by the designer.

## What it requires

Nothing beyond Smootify: it works on every plan.

## Attributes on the element

- **It reads** `data-url`.

## Loading

Its code loads only on pages that have `smootify-error-banner`.
