无法覆盖某些默认图片属性

Question

我有一个卡身，并且卡身内，我想要一张封面图片和顶部，那张照片的作者的姓名和照片，但现在，作者图片太大了，几乎无法覆盖整个卡身遮盖了卡片背景图像。如何将作者图片缩小到30x30px左右。现在是160x160px。

<div key={photo.id} className="grid__item card">
        <div className="card__body">
          <img
            src={photo.urls.small}
            alt=""
            onClick={() => setModalIsOpen(true)}
          />
          <div className="card__footer media">
            <img
              src={photo.user.profile_image.small}
              alt=""
              width="30px"
              className="media__obj"
            />
            <div className="media__body">
              <a href={photo.user.portfolio_url} target="_blank">
                {photo.user.name}
              </a>
            </div>
          </div>
        </div>
      </div>
