Product Detail Page Adding Lines & Changing Image Controls

12 hours ago, RGCreative said:

Hello!
Could do with some help making some changes to product detail pages please.

1. I'd like to introduce a line at the top and bottom of the product detail section. I've managed to add a line at the bottom using the product 'additional info' function (see attached) but this is a time consuming way to go about it for each product. Hoping there's an easy css fix to add it to both top and bottom of the section?

2. Also, I've been playing with the product image arrows but they're not quite as I'd like them. Ideally, I'd like them to match those on the gallery slideshow (see attached) I have on the homepage - just a bit smaller and neater.
