How do I make the prev/next links bigger on the product info page?

[maxreefer]

I would like to change the layout from the product info page.
Which file do I have to edit?

Below is a picture to illustrate what I would like to change:
1. I want the prev - next etc text to be bigger
2. I would like to have a little more space between the prev-next etc text and the heading of the product which is below

Thanks for any help

Since you appear to be using text links, try adjusting the font size for .navNextPrevList. Add to your stylesheet

.navNextPrevList {
    font-size: 1.2em;
    margin-bottom: 2.0em;
    }

Adjust to taste.
If that doesn't help, post a link so we can see your site live.
