Switching-off borders?

Hi folks -- I wonder if any of you could give me some advice on a matter to do with my site design. I did not design the site myself but got professional web developers to do it for me -- and I'm very happy with the design. But I've now noticed that the appearance of the products on the 'Featured Products' page looks better than the products category pages. I think the product category pages would look better if they did not have the pink border around them but I don't know how to remove the border and I'm scared to touch anything incase I mess it up. And -- trust me -- I could, as I don't have a clue about how to do such a thing. The site has been 'live' for about a month and I'm 'signed-off' with the designers, so I'd like to be able to do it without calling in a professional, if possible. :cry:

The site is at:www.larkinandcatcher.com

take a look at your stylesheet_new.css file and find this line:
(around line 529)

.centerBoxContentsProducts {
text-align: center;border:1px solid #FC55FF;margin:2px;font-size:70%;
}

and change it to this:

.centerBoxContentsProducts {
text-align: center;border:0px solid #FC55FF;margin:2px;font-size:70%;
}

simply change the border pixel to 0. hope tht works. just change it back to 1px if you want to enable the border line.
