css - 图像在圆形图像上被拉伸(stretch) - Bootstrap 和 SCSS

Question

请帮忙!!!

我正在使用引导卡来制作我网站的一部分。我在卡片的圆形图像中遇到问题。我希望我的图像在将它们放入卡片的图像圈时不会拉伸(stretch)。有没有办法可以在以圆圈显示图像的同时放大图像的中间，还是我在 scss 代码中做错了什么？？

问题是:

预期输出:

这些图像的尺寸:

910x592、1230x802、1230x794

引导代码:

卡片部分的 SCSS:

.about-cards-section{

    .card-wrapper{
        margin: 5% 0;

        .card-style{
            text-align: center;
            border-radius: initial;
            border: initial;


            .circle-image{

                width: 60%;
                height: 200px;
                text-align: center;
                display: block;
                margin-left: auto;
                margin-right: auto;
                margin-bottom: 20px;
            }
            .card-title{

                text-transform: uppercase;
                letter-spacing: 1.1px;
            }
            .card-text{
                font-family: MerriweatherRegular;
                font-size: 22px;
                line-height: initial;

            }
        }
}

在我看来，你只需要调整.circle-image 类的宽度和高度，并添加object-fit: cover; 属性。但是由于您使用的是 Bootstrap，我们可以使用 BS4 中的预定义类最小化您的 css

示例:

.card-wrapper {
  margin: 5% 0;
}

/* You can adjust the image size by increasing/decreasing the width, height */
.custom-circle-image {
  width: 20vw; /* note i used vw not px for better responsive */
  height: 20vw;
}

.custom-circle-image img {
  object-fit: cover;
}

.card-title {
  letter-spacing: 1.1px;
}

.card-text {
  font-family: MerriweatherRegular;
  font-size: 22px;
  line-height: initial;
}
