HTML5 Bootstrap3：并排显示信用卡到期月份和年份？

Question

我一直在使用 Bootstrap v3 制作移动友好的支付表单/应用程序。我在显示并排字段 (2) 和普通文本字段时遇到了一些困难。有信用卡到期月份和信用卡到期年份。更改页面宽度时，标签/字段不会以相同的方式进行调整。下拉菜单有时也很难阅读。我应该只对下拉列表应用一个固定的吗？有什么建议么？请参阅 JSFiddle 示例。

我想这就是你要找的。我重新创建了您的布局并使其稀疏，因此您可以看到我做了什么以及它与您的代码相比如何。基本上，我认为您与cols 混淆了，这真的很容易做到。 :)

<div class="container">
    <form class="form-horizontal">

        <label class="col-sm-5 control-label">Card Number</label>
        <div class="col-sm-7">
            <div class="form-group">
                <input type="text" class="form-control">
            </div>
        </div>

        <label class="col-sm-5 control-label">Card Expiration</label>
        <div class="col-sm-7">
            <!-- wrap in a .row to remove padding so it matches input:text field -->
            <div class="row">
                <div class="col-sm-6">
                    <div class="form-group">
                        <select class="form-control">
                            <option>Year</option>
                        </select>
                    </div>
                </div>
                <!-- offset by 1 so it's not smashed up to the year select -->
                <div class="col-sm-5 col-sm-offset-1">
                    <div class="form-group">
                        <select class="form-control">
                            <option>Month</option>
                        </select>
                    </div>
                </div>
            </div>
        </div>

    </form>
</div>
