change required in navigation types

Hi, Greetings..!
can someone help me with navigation type?
I have to put next and previous buttons displayed on screen in middle and not at the bottom. Like I highlighted in the screenshot that I have attached.

please help me, what code changes do i need to do for getting navigation buttons on screen?

Thanks in advance.

This isn't a particularly easy change to make. You would need to use css (and possibly some javascript) to make the buttons appear in those locations. You would also need to adjust the width of the pageHolder div as the page content would normally fill the width of this area. If you didn't adjust this then your buttons would often overlap the content on the page. This is a change that I wouldn't recommend doing unless you are very comfortable writing your own css and are able to do a lot of testing.
