Hover effects on site links

Site URL: https://www.inclusivecreative.services/

Hi, I'm trying to figure out how to add a hover effect to hyperlinks in the body of my site (navs are fine). Right now the only design option to indicate links is a color and I feel it looks like a design feature not a link. I've tried adding some css to make this happen, but I'm not sure which selector to choose. I'm using the Hayden template

Add to Home > Design > Custom CSS

#page .html-block a:hover {
    color: red;
}
