Bootstrap col 右对齐 [英] Bootstrap col align right

问题描述

我正在尝试用 2 列创建一行.左边的一个 col 内容左对齐，第二个 col 内容右对齐(旧的 pull-right).

如何在 alpha-6 中处理这个问题?

我已经尝试了一些东西，但这是我目前所拥有的.我错过了什么?

<div class="col">left</div><div class="col ml-auto">内容需要右对齐</div>

解决方案

Bootstrap 5(2021 年更新)

在 Bootstrap 5 中右对齐元素...

float-right 现在是 float-end
text-right 现在是 text-end
ml-auto 现在是 ms-auto

引导程序 4(原始答案)

对块元素使用 float-right，对内联元素使用 text-right:

<div class="col">left</div><div class="col text-right">内联内容需要右对齐</div>
<div class="row"><div class="col">left</div><div class="col"><div class="float-right">元素需要右对齐</div>

如果 float-right 不起作用，记住 Bootstrap 4 现在是 flexbox，许多元素是 display:flex 可以阻止 float-right 工作.

在某些情况下，诸如 align-self-end 或 ml-auto 之类的实用程序类可用于右对齐 flexbox 容器内的元素，如 Bootstrap 4 .row、Card 或 Nav.ml-auto (margin-left:auto) 在 flexbox 元素中用于将元素向右推送.

Bootstrap 4 对齐正确示例

I'm trying to create a row with 2 cols. One col on the left with its contents aligned left, and the second col with its contents aligned right (old pull-right).

How to do I go about this in alpha-6?

I've tried a few things, but this is what I have so far. What am I missing?

<div class="row">
    <div class="col">left</div>
    <div class="col ml-auto">content needs to be right aligned</div>
</div>

解决方案

Bootstrap 5 (update 2021)

To right align elements in Bootstrap 5...

float-right is now float-end
text-right is now text-end
ml-auto is now ms-auto

Bootstrap 4 (original answer)

Use float-right for block elements, or text-right for inline elements:

<div class="row">
     <div class="col">left</div>
     <div class="col text-right">inline content needs to be right aligned</div>
</div>
<div class="row">
      <div class="col">left</div>
      <div class="col">
          <div class="float-right">element needs to be right aligned</div>
      </div>
</div>

If float-right is not working, remember that Bootstrap 4 is now flexbox, and many elements are display:flex which can prevent float-right from working.

In some cases, the utility classes like align-self-end or ml-auto work to right align elements that are inside a flexbox container like the Bootstrap 4 .row, Card or Nav. The ml-auto (margin-left:auto) is used in a flexbox element to push elements to the right.
