html - 卡片图像对齐

Question

我想将卡片中的图像固定在卡片主体的顶部。我已经尝试过 bottom: 0 但它不起作用。我希望卡体具有固定高度并固定在底部（正在工作）。但我希望图像固定在顶部，因为它们具有不同的大小并且会以不同的方式缩放。请有人帮忙。

<div class="card" style="width: 18rem;">

            <img class="card-img-top fluid-img" src="briefcase.png" alt="Card image cap">
        <div class="card-body">
                <h5 class="card-title">Suit</h5>
                 <p class="card-text">Professional, business executive look.</p>
                 <p class="text-center">€299</p>
                <a href="#" class="btn btn-success btn-block">Add to cart</a>

.card-img-top {
  width: 100%;
  border-top-left-radius: calc(0.25rem - 1px);
  border-top-right-radius: calc(0.25rem - 1px);
}

.card {
  position: relative;
  display: -ms-flexbox;
  display: flex;
  -ms-flex-direction: column;
  flex-direction: column;
  min-width: 0;
  height: 650px;
  word-wrap: break-word;
  background-color: #fff;
  background-clip: border-box;
  border: 1px solid rgba(0, 0, 0, 0.125);
  border-radius: 0.25rem;
}

.card-body {
  -ms-flex: 1 1 auto;
  flex: 1 1 auto;
  padding: 1.25rem;
  bottom: 0;
  position: absolute;
}

<div class="card" style="width: 18rem;">

  				<img class="card-img-top fluid-img" src="briefcase.png" alt="Card image cap">
  			<div class="card-body">
    				<h5 class="card-title">Suit</h5>
   					 <p class="card-text">Professional, business executive look.</p>
   					 <p class="text-center">€299</p>
    				<a href="#" class="btn btn-success btn-block">Add to cart</a>
  </div>
