CustomHtmlEditorPlaceholder (Atlassian Confluence 8.8.0 API)

```
public interface CustomHtmlEditorPlaceholder
```
An interface implemented by a Macro that wishes to provide its own HTML placeholder to the Confluence Editor.

It should be noted that current implementation restrictions on the editor mean that the custom placeholder must be a single non-editable HTML element. It should be either an IMG tag or an OBJECT tag.

Since:

4.0
