[Share] List Simple: Hover show Text, Button, Overlay

To achieve layout like this

#1. First, you need to find List Section ID.

In my example, we will have:

section[data-section-id="67079915aa69e8040ff7de42"]

#2. Use this code to Website Tools > Custom CSS

section[data-section-id="67079915aa69e8040ff7de42"] {
  li.list-item {
        pointer-events: initial !important;
        position: relative;
    }
    /* image */
    li.list-item .list-item-media-inner:before {
        content: "";
        background-color: rgba(0,0,0,0.5);
        position: absolute;
        top: 0;
        left: 0;
        width: 100%;
        height: 100%;
        z-index: 9999;
        opacity: 0;
        pointer-events: none;
        transition: all 0.5s ease;
    }
    li.list-item:hover .list-item-media-inner:before {
        opacity: 1;
        transition: all 0.5s ease;
    }
    .list-item-content {
        position: absolute;
        top: 50%;
        left: 50%;
        transform: translate(-50%,-50%);
        width: 100%;
        opacity: 0;
        transition: all 0.5s ease;
        z-index: 9999999;
    }
      /* text color */
    .list-item-content * {
        text-align: center !important;
        color: #fff !important;
    }
    li.list-item:hover .list-item-content {
        opacity: 1;
        transition: all 0.5s ease; 
    }
}
