即使通过引导程序设置宽度后，控件也无法正确对齐

Question

我正在创建一个UI，每行包含四个控件。它会有一个标签和控件，然后是另一个标签和控件。如果您在我的标记中看到，我已经为标签设置了col-md-2，并为控件设置了col-md-4，但是第二个控件似乎已经包装好并继续下一行。我不确定为什么要这样做，因为总宽度为12。如果您单击右上角的“编辑”按钮，则可以切换以查看控件

我还创建了一个堆栈闪电来复制问题

Answer 1

我认为答案是因为您的标签左边有空白。如果将其取出，则所有元素都应排成一行。

通常，当项目不适合Bootstrap行时，我的第一检查始终是查看是否应有多余的边距或填充。

如果在标签前确实需要额外的间距，请尝试将它们包装在包含div的位置，然后在该包装上添加.col- *类。然后，您可以尝试在标签上添加额外的间距。

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

Answer 2

我整理了一下代码，看看是否适合您。

.panel-heading {
  color: black;
  /* background-color: #F5F7F7; */
  border-color: #ddd;
  overflow: hidden;
  padding-top: 5px;
  padding-bottom: 5px;
}

.panel-heading .left-label {
  display: inline-block;
  padding-top: 5px;
  font-size: 18px;
  font-weight: bold;
}

.panel-heading label {
  margin-bottom: 0;
}

    </div>

  </div>
</div>

如果您仍想在标签上设置左页边距，则可以将label包装在包含div的标签中：

.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中：

.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">
        ...
