Hi,

I want to modify the margins in the product page.

As you can see in the attached picture there ir a lot of space between the principal image and the thumbnail images.

I have used the google tools and I think I have to change something in the class=hikashop_product_main_image but I don't know where I can find the file that has the code. I tried in Configuration->display->public CSS



Thank you for your support.
