Bootstrap表单设计问题

Question

在我的引导程序表单中，行之间存在不寻常的间隙，尽管它们具有相似的声明。此外，选择框看起来比我在示例中看到的要大，

这是问题，

知道什么是错的吗？

这是代码，

<div class="panel-body">
                <div class="tab-content">
                        <div id="content_obsinfo" class="tab-pane active">
                            <div class="col-sm-12">

当我检查第一行和第二行时，清楚地看到差异

Answer 1

项目中的另一个CSS可能吗？

在col-sm里面排？

排在行内？
