即使通过引导程序设置宽度后控件也无法正确对齐答案

【问题标题】：Controls not aligning correctly even after setting width via bootstrap即使通过引导程序设置宽度后控件也无法正确对齐
【发布时间】：2019-05-31 15:55:33
【问题描述】：

我正在创建一个每行包含四个控件的 UI。它将有一个标签和控件，然后是另一个标签和控件。如果您在我的标记中看到，我已将 col-md-2 设置为标签，将 col-md-4 设置为控件，但第二个控件似乎已换行并进入下一行。我不知道它为什么这样做，因为它总共宽度为 12。如果单击右上角的编辑按钮，您可以切换以查看控件

我还创建了一个堆栈闪电战来复制问题

stackblitz 链接不起作用

标签： html css bootstrap-4

【解决方案1】：

我认为答案是因为您的标签有一个左边距。如果你把它拿出来，元素应该都适合一行。

通常，当项目不适合 Bootstrap 行时，我的第一个检查始终是查看不应该有的地方是否有额外的边距或填充。

如果您确实需要标签前的额外间距，请尝试将它们包装在包含 div 中，并在该包装上添加 .col-* 类。然后你可以尝试在标签上添加额外的间距。

<div class="col-md-4"> <label></label> </div>

【讨论】：

如果我要删除 marginleft 并将控件放在标签中，那么控件将包裹标签。我需要标签和控件在同一行
名称
测试名称
我没有 stackblitz——你的链接失效了——但我有这个 CodePen，希望对我有所帮助。检查 CSS 第一行中的注释。这允许项目适合一行。 codepen.io/anon/pen/LowGaa

【解决方案2】：

我稍微整理了您的代码，看看这是否适合您。

如果您仍想在标签上设置左边距，您可以将 label 包裹在包含 div 的内容中：

.col-form-label {
    margin-left: 0.5rem;
}

<div class="form-group row">
    <div class="col-md-2">
      <label for="inputName" class="col-form-label">Name</label>
    </div>
    <div class="col-md-4">
        ...

或将标签文本包装在span：

.col-form-label span {
    display: inline-block;
    margin-left: 0.5rem;
}

<div class="form-group row">
    <label for="inputName" class="col-md-2 col-form-label"><span>Name</span></label>
    <div class="col-md-4">
        ...
