Show Read More in Events Summary Block (7.1)

Resolved: Changed "bottom" to -20px

I'd like to add "Read More" to Event Listings displayed in a summary block. Previous similar question provided code which provides display but text conflicts with excerpt. I presume this can be fixed with updating "position" but I don't know what to use in there. I tried modifying "bottom" but that doesn't change anything.

body#collection-64c524cfef61a10b12b6c05b
.summary-title-link:after {
    content: "Read more";
    font-size: 14px;
    color: var(--paragraphLinkColor);
    font-family: Work Sans;
    font-weight: 400;
    font-style: normal;
    letter-spacing: 0em;
    text-transform: none;
    position: absolute;
    bottom: 60px;
    left:0;  
}
