    }
  ]
}
...

index.html

<body>

  <script src="bundle.js"></script>

  <ewc-dialog></ewc-dialog>

  <script>
    document.addEventListener("DOMContentLoaded", function(event) {
      const el = document.getElementsByTagName("ewc-dialog")[0]
      el.title = "Information"
      el.bodyHtml = "<ul> <li>This</li> <li>That</li> </ul> And some more."
      el.visible = true
    })
  </script>

</body>

main.js

import "@ewc-lib/ewc-css/ewc.css"
import "@ewc-lib/ewc-dialog"

Focus trap

If bodyHtml contains elements which should be included in the focus trap - for example links - there's the possibility to set the focus trap's last element (to the last focusable element from the body html) - after which the first element (the close button) is focussed again, completing a cycle.

Example:

document.getElementById("infoModal").bodyHtml = `<a id="dialog_last_element" href="https://ec.europa.eu/eurostat" title="Link to Estat">Some Link Text</a>`
document.getElementById("infoModal").visible = true
document.getElementById("infoModal").focusTrap.setLastElement(document.getElementById("dialog_last_element") )

This way, the focus is still trapped within the dialog but also includes tab-focusable elements within the bodyHtml.

Note that setLastElement() is called after the visible setter.
