Change hover to touch

问题

I am trying to make this effect touch-friendly. I have a thumbnail gallery that has titles and descriptions. The title is displayed on load, and when the user hovers over the thumbnail they see the longer description. Then they can click on the entire image to go to the linked page.

I have tried several options, like this one but none seem to work. I'd be fine if the hover acted as a touch to display caption info, and a second touch will open the link that is assigned to the image. Right now, the first touch displays the description for a half second, then follows the link.

I'm open to CSS or js options- I just need to get something to work!

.caption {
    position: relative;
    overflow: hidden;

    /* Only the -webkit- prefix is required these days */
    -webkit-transform: translateZ(0);
            transform: translateZ(0);
}

.caption::before {
    content: ' ';
    position: absolute;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    background: transparent;
    transition: background .35s ease-out;
}

.caption:hover::before {
    background: rgba(0, 0, 0, .5);
}

.caption__media {
    display: block;
    min-width: 100%;
    max-width: 100%;
    height: auto;
}

.caption__overlay {
    position: absolute;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    padding: 10px;
    color: white;

    -webkit-transform: translateY(100%);
            transform: translateY(100%);

    transition: -webkit-transform .35s ease-out;
    transition:         transform .35s ease-out;
}

.caption:hover .caption__overlay {
    -webkit-transform: translateY(0);
            transform: translateY(0);
}

.caption__overlay__title {
    -webkit-transform: translateY( -webkit-calc(-100% - 10px) );
            transform: translateY( calc(-100% - 10px) );

    transition: -webkit-transform .35s ease-out;
    transition:         transform .35s ease-out;
}

.caption:hover .caption__overlay__title {
    -webkit-transform: translateY(0);
            transform: translateY(0);
}
