Here I feel in practice what I have understood what I see is what I have.
Visual Editing (WYSIWYG) is best for New pages and Beginners and Code Editing is best for Existing pages or if you already have a basic knowledge of HTML. Saving your page after it has been altered by WYSIWYG is permanent and can not be reversed. Be Careful when going back and forth between modes and only Save the page you are happy with after you have reviewed your HTML in the Code Editor.
WYSIWYG (what you see is what you get) n. characteristic of applications in which a document appears on-screen exactly as it will appear when printed (Computers).

I wrote to ask for help:

I read between the tip of the day the message below. I would ask what is meant in practice with WYSIWYG in the development of a web page. In particular I would ask how to access to the function WYSIWYG. I use each day the software CoffeeCup HTML Editor Version 2007, but I do not understand how I could use WYSIWYG. Perhaps the message leads to an erroneous conclusion for how is it written? If there is, can you submit the choice menu?

The answer:

Hello Mario,
WYSIWYG stands for What You See Is What You Get, and basically is an acronym for designing your pages visually. If you open a new page and switch to the Visual Editor tab, you can insert images, text, and use other functions without knowledge of HTML. Let us know if you have any other questions.
Thank you.

WYSIWYG sta per ciò che vedi è ciò che si ottiene, e sostanzialmente è un acronimo per progettare le vostre pagine visivamente. Se si apre una nuova pagina e si passa al Visual Editor TAB, si può inserire immagini, testo, e le altre funzioni senza conoscenze di HTML. Fateci sapere se avete altre domande.
