If it is for the purpose of editing some rich content, I don't think that will be possible, as a textarea support text only and does not display HTML as anything but plain text. You could however use a div element, and apply it to that instead.

If you need to post the HTML somewhere, and that is the reason you want to put it on a textarea, I guess you could use a div for the editor, and then copy the content of the div to a hidden input, whenever the content changes. You could then use the hidden input to post the HTML.

The documentation on MDN has an example of a rich text editor that uses a div .
