The web version doesn’t have the same view options as the desktop version. If you’re using the online version of Microsoft Word, this is the best way to display one page at a time in Microsoft Word. It should either appear alongside the existing page or below it, depending on what you chose. If the document is not already two or more pages long, such as what happens when you open Word to try this, add another page with Ctrl + Enter.
Go back to the left and change it to 100%.
Once you’ve done this, you’ll see that Word’s zoom level is going to change.
