Store Design

Hi,

This works! Thanks so much :slight_smile:

However, I am unable to configure the height/width of the afterpay icon. Where do i put the code

#shopify-section-footer > footer > div:nth-child(3) > div > div.grid__item.small–hide.one-half.site-footer-item-center-vertically > div > ul > li:nth-child(6) > img{

width: 100px;
height: 70px;

} -

in the theme liquid?
