html - 即使通过 Bootstrap 设置宽度后，控件也无法正确对齐

Question

我正在创建一个每行包含四个控件的用户界面。它会有一个标签和控件，后面跟着另一个标签和控件。如果您在我的标记中看到，我已经为标签设置了 col-md-2，为控件设置了 col-md-4，但是第二个控件似乎换行并转到下一行。我不确定为什么要这样做，因为它的总宽度为 12。如果您单击右上角的“编辑”按钮，您可以切换以查看控件

我还创建了一个 stackblitz 来重现这个问题

    label {
        margin-left: 0.5rem;
        vertical-align: middle

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

    .panel-heading .left-label {
        display: inline-block;
        padding-top: 5px !important;

    }
    .panel-heading label {

Answer 1

我认为答案是因为您的标签留有边距。如果你把它去掉，所有元素都应该放在一行中。

通常，当元素不适合 Bootstrap 行时，我的第一个检查始终是查看是否有额外的边距或填充在不应该的地方。

如果您确实需要标签前的额外间距，请尝试将它们包裹在包含的 div 中，然后在该包裹上添加 .col-* 类。然后您可以尝试向标签添加额外的间距。

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