html - 未应用 Bootstrap 4 卡片组等高

Question

我的问题是 card-deck 的属性(.card-deck 类创建了一个高度和宽度相等的卡片网格。布局将在您插入更多卡片时自动调整。)似乎不是申请。

这是代码:

<div class="container-fluid"> 
<div class="card-group">
    <div class="card" id="col1m">
        <div class="card-header text-center" style="color: #888" id="display1_title">CAUDAL abcdefghi (BPM)</div>
        <div class="card-body text-center" id="col1">
            <p class="card-text" style="font-family:roboto; font-weight: bold; color:#888" id="display1_value">0</p>
        </div>
    </div>

    <div class="card" id="col2m">
        <div class="card-header text-center" style="color: #888;" id="display2_title">VOL. TOTAL (BBL)</div>
        <div class="card-body text-center" id="col2">
            <p class="card-text" style=" font-family:roboto; font-weight: bold;   color: #888" id="display2_value"> 0 </p>
        </div>
    </div>
</div>
</div>
