When you surf the Internet with the Safari Browser on iPhone X, you may not see the entire website on your screen in landscape mode. The reason is that half of the page is covered by the bookmarks bar.
But most of the time, you also want to display the website in full screen in landscape format. To do this, you'll need to make the following settings on your iPhone X:
If you have opened the Safari app on your iPhone X and are holding your phone in Landscape mode, simply tap the blue "Book" icon at the top left of the input field.
This will turn the book icon white and you'll see the web page in full screen when you hold the phone in landscape mode.
To re-display the bookmarks bar in Safari Browser, tap the book icon again.
Done, you know now how to hide the Bookmarks Bar on iPhone X.
