Answer 1

缩放图像作为背景。

 <div class="card-image" style="background-image: url('img/4.jpg');"></div>

在CSS中

.card-image {
  background-repeat: no-repeat;
  background-position: 50% 50%;
  background-size: cover;
  width: 300px;
  height: 300px;
}

Answer 2

可以改变CSS

.card-image{ height: 300px; //or however you want it width:auto; //so that the image ratio stays the same }
