推荐答案

只需将my-auto用于垂直中心 ...

  <div class="card">
        <img class="img-fluid card-img" src="https://snap-photos.s3.amazonaws.com/img-thumbs/960w/1U2EGZ07GU.jpg" alt="Deer in nature">
        <div class="card-img-overlay d-flex">
            <div class="my-auto mx-auto text-center">
                <h4 class="card-title">Animal Farm</h4>
                <h6 class="text">George Orwell</h6>
                <p class="card-text">Tired of their servitude to man, a group of farm animals revolt and establish their own society...</p>
            </div>
        </div>
  </div>
