Specifically, the next and previous buttons at the bottom. I don't want to display it like a hyperlink (i.e. underlined and blue). Currently, it displays boxes around the two words on hover. However, I'd rather that it be obvious without having the user scroll over the text.
Commonly, text that is clickable is underlined and colored differently. Stylistically, just keeping all clickable text styled the same will lead to the user being able to better predict what text will also be clickable later down the road.
