How to align button to right in bootstrap 4
提问by Nathan Ruth
I tried looking this up here but I can't find anything related to this specific problem.
我尝试在此处查找此内容，但找不到与此特定问题相关的任何内容。
I'm trying to make a header which has a button on the left and right of the screen with a logo in the middle, but whenever I make the window smaller or larger the button on the right doesnt stay aligned.
我正在尝试制作一个标题，它在屏幕的左侧和右侧有一个按钮，中间有一个徽标，但是每当我使窗口变小或变大时，右侧的按钮就不会保持对齐。
Here is the code:

<header>
<div id="container-fluid">
<div class="row">
<div class=" col-2">
Menu

<div class="col-2 float-right">
Contact
</div>
</div>

</header>

wrap your content so it can be aligned according to the parent container.
包装您的内容，以便它可以根据父容器对齐。

You havn't defined what size of column grid you are using. Using col-xs,col-sm, col-md,col-lg will have different effects for the particular code. Run the snippet code in full page below and see how the col-size affects when the browser is resized.
您还没有定义您使用的列网格的大小。使用 col-xs,col-sm, col-md,col-lg 将对特定代码产生不同的影响。在下面的整页中运行片段代码，并查看调整浏览器大小时 col-size 的影响。
Update - Bootstrap 4 has replaced the col-xs with col- .
更新 - Bootstrap 4 已将 col-xs 替换为 col- 。
