Squarespace 7.1, product thumbnails slideshow, how to create an even viewing of thumbnail images without a slider and how to setup customer size....solved.

This is what I did to change the appearance of the slideshow thumbnail views below the product image when on desktop.

.tweak-product-basic-item-gallery-aspect-ratio-169-widescreen .ProductItem-gallery-thumbnails-item {
    height: 45px;
    width: 80px;
}
.tweak-product-basic-item-thumbnail-placement-below .ProductItem-gallery-thumbnails-item {
    margin-right: 0px;
}
.tweak-product-basic-item-gallery-design-slideshow.tweak-product-basic-item-thumbnail-placement-below .ProductItem-gallery-thumbnails {
    overflow-x: hidden;
    text-align: center;
}

I am trying to post all of my changes/solutions to this forum for the new 7.1, but my code is all mixed up, so I apologize if I missed something.  If anyone has any issues, please comment below.
