Bootstrap停止在移动宽度环绕的内联输入和按钮

Question

我在输入文本框的两侧都有小按钮。它在桌面屏幕宽度上显示OK。但是大约700个像素，所有三个对象都包装成不同的行。我已经尝试将它们放入行和列中。这只会让事情变得更糟;即使在宽屏幕宽度下也没有显示内联。

<div class="form-inline">
    <div class="row">
        <div class="col-xs-9">
            <button id="mnBlue" type="button" class="btn btn-warning glyphicon glyphicon-arrow-down"></button>
            <div class="form-group">
                <label class="sr-only">Blue Quantity</label>
                <input class="form-control" id="QuantityEdit_Blue" name="QuantityEdit.Blue" type="number" value="" />
                <button id="plBlue" type="button" class="btn btn-success glyphicon glyphicon-arrow-up"></button>
            </div>
        </div>
    </div>
</div>
<div class="form-group form-inline">

    <label class="control-label">Quantity</label>
    <div class="input-group">
        <button id="mnRed" type="button" class="btn btn-warning glyphicon glyphicon-arrow-down"></button>
        <input class="form-control" id="QuantityEdit_Red" name="QuantityEdit.Red" type="number" value="" />
        <button id="plRed" type="button" class="btn btn-success glyphicon glyphicon-arrow-up"></button>
        <span class="field-validation-valid text-danger" data-valmsg-for="QuantityEdit.Red" data-valmsg-replace="true"></span>
    </div>
</div>

链接屏幕截图中的顶部按钮和文本框显示我正在尝试在手机大小的屏幕上实现的显示。底部显示移动屏幕宽度发生的情况。
