Flexbox卡无法填充剩余空间

Question

我认为图片是自我解释

我希望这些卡片能填满剩余区域。无论如何，我尝试都会失败...

<div class="card">
    <div class="card-header bg-primary text-light">
        Title
    </div>
    <div class="card-body">
        <div class="d-flex">
            <div class="p-2">
                <ul class="list-group">
                    <li class="list-group-item">abc cba abc</li>
                    <li class="list-group-item">cba abc cba</li>
                </ul>
            </div>
            <div class="flex-column">
                <div class="card p-2 flex-grow-1" style="margin-bottom: 5px;" *ngFor="let phraseByCategory of queries.phrasesByCategory">
                    <h5 class="card-title"> {{phraseByCategory.category}}</h5>
                    <div class="card-body">
                        <textarea class="form-control"></textarea>
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>

您应该在弹性容器flex-grow-1中添加d-flex，因为display: flex仅影响一个1深层。

display属性仅影响给定元素的直接呈现

display docs

<div class="card">
    <div class="card-header bg-primary text-light">
        Title
    </div>
    <div class="card-body">
        <div class="d-flex">
            <div class="p-2">  <!-- they are on same level -->
                <ul class="list-group">
                    <li class="list-group-item">abc cba abc</li>
                    <li class="list-group-item">cba abc cba</li>
                </ul>
            </div>
            <div class="flex-column flex-grow-1"> <!-- here -->  <!-- they are on same level -->
                <div class="card p-2" style="margin-bottom: 5px;" *ngFor="let phraseByCategory of queries.phrasesByCategory">
                    <h5 class="card-title"> {{phraseByCategory.category}}</h5>
                    <div class="card-body">
                        <textarea class="form-control"></textarea>
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>
