Excessive white space / gap on product pages

Page URL

The gap between the main product description block and the 'additional info' appears on all devices.

I've tried this code but it doesn't work. The first one only moves the bottom block up  ~20 pixels

/* space under product thumbnails */
.product-description {
    margin-top: -300px;
}

/* space between additional info - photo */
section.ProductItem-additional {
    margin-top: -300px !important;
}
