如何使用引导程序将图像设置为相同高度？

Question

我正在尝试为所有卡放置相同大小的图像，但是有些图像的高度已经很小，那么该如何解决呢？

<div class="row">
    <div class="col">
        <div class="card h-100" style="width: 18rem;">
            <img class="card-img-top" src="/assets/prewedding/pic1.jpg">
        </div>
    </div>
    <div class="col">
        <div class="card h-100" style="width: 18rem;">
            <img class="card-img-top" src="/assets/prewedding/pic2.jpg">
        </div>
    </div>
</div>

您只需要设置from pandas import DataFrame df = DataFrame([ {"User": "User1", "Action": "A", "id": 1}, {"User": "User1", "Action": "B", "id": 2}, {"User": "User1", "Action": "B", "id": 3}, {"User": "User1", "Action": "C", "id": 4}, {"User": "User1", "Action": "C", "id": 5}, {"User": "User1", "Action": "C", "id": 6}, {"User": "User2", "Action": "A", "id": 7}, {"User": "User2", "Action": "B", "id": 8}, {"User": "User2", "Action": "B", "id": 9}, {"User": "User2", "Action": "C", "id": 10}, {"User": "User2", "Action": "C", "id": 11}, {"User": "User2", "Action": "C", "id": 12}, {"User": "User3", "Action": "A", "id": 13}, {"User": "User3", "Action": "B", "id": 14}, {"User": "User3", "Action": "B", "id": 15}, {"User": "User3", "Action": "C", "id": 16}, {"User": "User3", "Action": "C", "id": 17}, ]) print(df) df_agg = df.groupby(["Action", "User"]).agg({"id": ["count"]}) print(df_agg) df_result = DataFrame([ {"Action": "A", "Mean usage per user": 1}, {"Action": "B", "Mean usage per user": 2}, {"Action": "C", "Mean usage per user": 8 / 3}, ]) print(df_result) 即可覆盖容器，例如
