Answer 1

每当您在引导程序中使用表单元素时，建议您将该特定元素放在表单组类中 - 这样，每个元素下方都有一个 15px 的边距底部。

As per Bootstrap's form example: 将标签和控件包裹在 .form-group 中以获得最佳间距。

.inline-group {
  display: inline-block;
}

但是，form-group 是一个 block 属性，因此，它会在新行中删除每个表单元素，因此您可以添加另一个类，如 .inline-group 并使其成为 display:inline-block如图所示

这是由于您在模态中使用了.row。 .row 没有填充或边距。如果你不想改变你的标记，那么一点点“hack”可能是

.modal-body .row {
   padding-bottom: 16px;
}
