WYSIWYG

An editor that allows users to see what the end result will look like while the document is being created.

WYSIWYG (What You See Is What You Get) editors allow users to create and edit content in a form that closely resembles its appearance when printed or displayed as a finished product. For example, WYSIWYG editors are commonly used in website builders and word processors, where users can format text and images without needing to write HTML or other code.
