我可以在不使用响应的情况下解决这个问题吗？

Question

我在Bootstrap中使用了卡片元素，每当我放大时，这3张卡片之间的高度是不同的（因为卡片标题）。我该如何解决这个问题，我可以不使用响应技术@media 来解决吗？

这是我的 HTML 代码：

<div class="row">
        <div class="col-12 col-sm-12 col-md-4 col-lg-4 col-xl-4">
          <div class="card">
            <img src="img/card-img.png" class="card-img-top" alt="...">
            <div class="card-body">
              <h5 class="card-title">Massage Therapy</h5>
              <p class="card-text">Living winged said you darkness you're divide gathered and bring one seasons face great dr Waters firmamen: place which.</p>
              <button class="btn btn-hover">read more</button>
            </div>
          </div>
        </div>

        // I have to make the code section smaller, but 2 other cards are the same as the first one above
      </div>

和CSS：

.content > .container .row .card {
    padding: 1.9rem;
}

.content > .container .row .card > .card-body {
    display: flex;
    flex-direction: column;
    align-items: center;
    padding-top: 0;
    position: relative;
}

.content > .container .row .card > .card-body > h5 {
    font-size: 2.3rem;
    margin: 4.2rem 0 2.9rem 0;
}

.content > .container .row .card > .card-body > p {
    font-size: 1.4rem;
    margin-bottom: 4.5rem;
    line-height: 2.6rem;
}

.content > .container .row .card > .card-body > button {
    width: 14rem;
    height: 4.4rem;
    font-size: 1.4rem;
}

.cols 的高度都相同，因此您可以将卡片拉伸到所有列的 100%，这样无论内容或缩放如何，它们都将始终保持相同的高度。

.content > .container .row .card {
    height: 100%;
    padding: 1.9rem;
}

.content > .container .row .card {
    height: 100%;
    padding: 1.9rem;
}

.content > .container .row .card > .card-body {
    display: flex;
    flex-direction: column;
    align-items: center;
    padding-top: 0;
    position: relative;
}

.content > .container .row .card > .card-body > h5 {
    font-size: 2.3rem;
    margin: 4.2rem 0 2.9rem 0;
}

.content > .container .row .card > .card-body > p {
    font-size: 1.4rem;
    margin-bottom: 4.5rem;
    line-height: 2.6rem;
}

.content > .container .row .card > .card-body > button {
    width: 14rem;
    height: 4.4rem;
    font-size: 1.4rem;
}
