Oh creating a single html from that site I expect might be painful and difficult.
1) You have to learn how to use an html compiler although this can be done with a text editor by someone who knows what they are doing.
2) You might write the Vatican...they might have these already as a single html.
3) if not, you can do the following for EACH of the web sites html files to extract the html code. Sorry, this activity is drudgery.but you asked.
then using a Chrome browser; right click on that page to bring up a MENU ... select View page source (Ctrl + U) and the following screen will display
This is the start of numerous Genesis html file
links.. Now right click on
__P1.HTM (highlighted as a 2). Clicking will bring you to this page
...and you see displayed the first book in Genesis . You want the html that displays that .. Right click the screen and bring up the MENU again and select View page source (Ctrl + U) You should then see the first html file of this version of the Bible.
This is the html source for the pretty Genesis 1 display above. Copy it all as a text file and save it as Genesis1.htm You can view it in your WebViewer (see the initial link I provided earlier for an example of the technique showing how to make eBooks).
Unedited, the html looks like this viewed on the WebViewer
See the genesis aia.
Now, keep repeating for the rest of the books.... that is a lot of work. Then save separate html files and link them or combine them into a single html. Be aware,
my experience is all the New Testament will compile in App Inventor when used as separate html files but the Old Testament will not compile as AI cannot handle that many files.
Attached is a King James bible in English with all the books consolidated as a single html file (see the attached aia.) The app is made from the files from here
https://www.gutenberg.org/ebooks/10 Theoretically, you should be able to create a lot of individual html files or be able to consolidate them into a single html as show in the eBook example. Merging the individual files is possible. It would be time consuming and difficult to create something similar in Italian. Realistically, all the Old Testament files saved as multiple html files is not practical. However, a single HTML with all the Books works fine!
