how to make the text in the items to float above the image in SwipeJS?

I’m trying to duplicate this effect from the SwipeJS demo page, where the text floats on the bottom part, but not outside of, the image in each slide.

I’ve tried using slide-content like I see in the devtools and I also tried using title and subtitle classes like it says in the docs (in the parallax part). but they all fails, as in showing the texts below the image, instead of over the image. what am I doing wrong? any help is appreciated.

this is my code:

      var swiper = new Swiper(".mySwiper", {
        effect: "coverflow",
        grabCursor: true,
        centeredSlides: true,
        slidesPerView: "auto",
        coverflowEffect: {
          rotate: 50,
          stretch: 0,
          depth: 100,
          modifier: 1,
          slideShadows: true,
        },
        pagination: {
          el: ".swiper-pagination",
        },
      });

      html,
      body {
        position: relative;
        height: 100%;
      }

      body {
        background: #eee;
        font-family: Helvetica Neue, Helvetica, Arial, sans-serif;
        font-size: 14px;
        color: #000;
        margin: 0;
        padding: 0;
      }

      .swiper {
        width: 100%;
        padding-top: 50px;
        padding-bottom: 50px;
      }

      .swiper-slide {
        background-position: center;
        background-size: cover;
        width: 300px;
        height: 300px;
      }

      .swiper-slide img {
        display: block;
        width: 100%;
      }

      .swiper-slide .card-img-text {
        translatey: (-50%);
        mix-blend-mode: exclusion;
      }

      .swiper-slide .card-img-text * {
      }
