Impulse theme Removing boxes around product images

[RedCC]

Hello, I am having trouble removing the box around the product collections. I don't want any borders around any of my listed products in my store. Can someone please walk me through removing this? Thank you.

Please add the following code at the bottom of your assets/custom.css file.

.grid-product .grid-product__image-mask {
    border: 0px solid transparent !important;
    border-radius: 0px !important;
}

Thanks!

Hello! This worked great for my Dawn theme. Now I just have an extraneous } Character hanging on the top (please see below) Any ideas on how I can get this out?  Thanks!
