Question

我有一个bootstrap 4卡，我想将h3和输入组彼此对齐。

我尝试过在输入组中添加float-right，但是没有用。我也尝试过使h3和input-group inline-block仍然无效。附言我使用了内联样式表。

<div class="card-header">
    <h3 class="card-title" style="inline-block">Product List</h3>
    <div class="input-group input-group-sm col-sm-3" style="inline-block">
    <input type="text" class="form-control">
    <div class="input-group-append">
        <button class="btn btn-primary" type="button"><i class="fas fa-search"></i></button>
    </div>
    </div>
</div>

只需将.card-header放在该部分上，然后将title和.input-group包裹到.row > .col-*-*

Answer 3

只需在您的row类之前添加一个input-group类。因为您将col-sm-3与input-group一起使用，并且在元素的左右添加了15px的填充。通过添加row类，您将在输入组之前添加负边距，并使输入组与h3对齐。

<div class="card-header">
    <h3 class="card-title" style="inline-block">Product List</h3>
    <div class="row">
        <div class="input-group input-group-sm col-sm-3" style="inline-block">
            <input type="text" class="form-control">
            <div class="input-group-append">
                <button class="btn btn-primary" type="button"><i class="fas fa-search"></i></button>
            </div>
        </div>
    </div>
</div>
