Prev / Next links not working right

Hi,

I’m having a problem getting the prev/next links at the bottom of my blog posts to work. I’m using a child theme of twentysixteen.

Fore example – http://jsdonnelly.com/teaching/working-the-word/

The links are there but the clickable area is currently hovering somewhere above the “PREVIOUS” and “NEXT” labels.

Is there a way to make the whole previous / next area clickable rather than just that little tiny slither? Or even make the post titles the links?

Many thanks
