What you see is what you get (WYSIWYG)

WYSIWYG implies a user interface that allows the user to view something very similar to the end result while the document is being created. In general WYSIWYG implies the ability to directly manipulate the layout of a document without having to type or remember names of layout commands.

Microsoft Word is a good example of a WYSIWYG editor. The document you create looks like the final printed version. In web design, WYSIWYG HTML editors help content authors create web content without having to know how to write HTML.
