Hello,

Yes, the position of the label attribute depends on whether the product has the product gallery.

On your test site, you don’t have it, therefore the label attribute is in the middle of the image.

The bottom position starts with the product gallery (if it is).

If the product doesn’t have the product gallery then the bottom position starts with the main picture of the product.

So as to change the position of the label attribute on your test site, you should just change the bottom: 156px; value as you need.

Kind Regards
