How to disable the ‘prev & next navigation’ for all post pages

Hi all

First time on here so apologies if there’s a thread already been posted about something like this.

Can experience users here pls kindly advise how I can disable the ‘previous & next navigation’ for ALL post pages within the CSS of the One Page Express template standard version? I tried but failed & there seem to be a few minor errors which I’m not great at deciphering.

Many….. thanks in advance.
