css

.hover-text-3d {
    font-size: 7em;
}
.hover-text-3d {
    position: absolute;
    top: 50%;
    left: 50%;
    -webkit-transform: translate(-50%, -50%);
    -ms-transform: translate(-50%, -50%);
    -o-transform: translate(-50%, -50%);
    transform: translate(-50%, -50%);
    -webkit-text-fill-color: #fff;
    text-fill-color: #fff;
}
.hover-text-3d:before {
    position: absolute;
    overflow: hidden;
    width: 0;
    content: attr(data-text);
    -webkit-transition: 2s;
    -o-transition: 2s;
    transition: 2s;
    -webkit-text-fill-color: #aaf0d1;
    text-fill-color: #aaf0d1;
    -webkit-text-stroke-width: 2px;
    text-stroke-width: 2px;
    -webkit-text-stroke-color: #aaf0d1;
    text-stroke-color: #aaf0d1;
    -webkit-filter: drop-shadow(5px 5px 5px rgba(0, 0, 0, .8));
    -o-filter: drop-shadow(5px 5px 5px rgba(0, 0, 0, .8));
    filter: drop-shadow(5px 5px 5px rgba(0, 0, 0, .8));
