Remove card borders

[kpettit]

Hello I have found solutions to this on the forum that do not work with my site. 
I am looking to have the borders removed around the image/video cards, as well as my products.
This site/page is not live yet. Here is the URL

I have tried to put the following code under my assets- base css folder 
.card--outline:not(.card--soft) { border: 0rem solid transparent !important; }
.product__media-list .product__modal-opener { border: 0rem solid transparent !important; } 

I have had no results with that. 

TIA

Hi @kpettit 
Actually your product images have border please upload without border images.
