because this does not works to WYSIWYG editor.

But you know better if this can be done as product

Yes, the WYSIWYG editor is an inline document, not a textarea, and so cannot be assigned a placeholder attribute.

In order to change the CSS of the placeholder text, it is best to have CSS selectors loaded so that the code for all the different browsers can be included, and a class name can be assigned to the textarea element.
