使用Bootstrap 4模态框实现标签右对齐

Question

如何将这个标签右对齐？我只能将其左对齐。我必须覆盖Bootstrap 4的默认值justify-content: center到justify-content: right !important;但它仍然左对齐。如何将其右对齐？

<div class="modal-body">
    <form class="form-horizontal">
        <div class="form-inline">
            <label class="col-md-4">Type</label>
            <input class="col-md-8" type="email" class="form-control">
        </div>
    </form>
</div>

CSS：

div.form-inline label.col-md-4 {
    justify-content: right !important; 
}

Answer 1

向标签添加"class = text-right"

<div class="modal-body">
    <form class="form-horizontal">
        <div class="form-inline">
            <label class="col-md-4 text-right">Type</label>
            <input class="col-md-8" type="email" class="form-control">
        </div>
    </form>
</div>

Answer 2

您需要将它更改为：

div.form-inline label.col-md-4{
    justify-content: flex-end;
}

justify-content: right is not a valid value.

谢谢。我该如何使标签与输入组对齐到中心？ - Joseph

我上传了一张图片。我的意思是如何使得“类型”和“输入表单”的空间相同，以便它们看起来正确对齐，左右两侧看起来平衡。 - Joseph

我会为输入表单设置一个较小的宽度列。尝试使用.col-md-5或.col-md-6代替.col-md-8。由于输入占据整个容器的宽度，因此没有确切的方法来解决这个问题。 - Florin Pop

Answer 3

justify-content: flex-end 对我没有用（Bootstrap 4.1.0），但是 text-align: right 可以使用：

<style>
label { text-align: right }
</style>

或者在 .css 文件中：

.col-form-label { text-align: right }

Answer 4

Bootstrap 4从block布局转移到了flex布局。您需要使用justify-content: flex-end来适应您的情况。

$('#myModal').on('shown.bs.modal', function () {
  $('#myInput').focus()
})

div.form-inline label.col-md-4{
  justify-content: flex-end; 
}
