- Click the browser screen (on my iphone it's on the right side) to reveal the URL above
- To the left of the URL is an open book image shrouded in blue (reverse white with blue background)
- Click the open book image and presto! the Bookmarks panel should disappear.
The open book should now be simple outlined in blue still to the left of the URL. To get the Bookmarks panel back, click the open book again.
Note: There is an open book box in the Bookmarks pane. That is not the right one and will only bring up the list of booksmarks and make you frustrated. Be sure you're clicking the one to the left of the URL. If you don't see the URL go back to step #1.
I'm using 6s but assume the process is similar with other iPhone versions.
