WYSIWYG stands for ‘What You See Is What You Get’ editor. WYSIWYG editors are text editors that allow you to enter text into an area where you can apply formatting. And what you see as you’re typing is how it is presented when saved.
A WYSIWYG Editor stores the underlying data and formatting as HTML stands for HyperText Markup Language. It was developed as the standard for how to create, format and display web... to be displayed on websites in that exact format. You may think of this as the editor you see within Microsoft word. When you set text to bold or a heading and then print the text, it is the same formatting. Hence, what you see is what you get.
