First, thanks tuanphan, your other posts have already helped me multiple times. But I am using Carson (says Tremont family) and this did not work for me. I tried searching the view-source: of my site for most of these options and I did not find one that works. To many links on to many different backgrounds, the more I could access link color and hover color for different places, like navigation, would help a lot.
The site is not live yet. I think I figured it out. Similar to Square 7.1
.nav-item a:hover {
text-decoration: underline !important;
color: hsl(120, 87%, 52%) !important;
}
