btn-group创建第一个按钮太高 [英] btn-group create first button too hight

问题描述

我正在使用 btn-group 将 buttons 的宽度设置为100％，效果很好，但是我在第一个按钮上得到了一个奇怪的结果，实际上，如果您看一下在图片上:

I'm using btn-group to make the buttons 100% width, this works well but I get a strange result on the first button, infact if you look at the picture:

您会看到第一个按钮的高度过高，另外两个按钮过高.为什么会这样?

as you can see the first button is too height agains the other two. Why happened this?

这是我的代码:

<div class="btn-group btn-group-justified custom-class btn-block">
    <button type="button" class="btn btn-secondary btn-block">First</button>
    <button type="button" class="btn btn-secondary btn-block">Second</button>
    <button type="button" class="btn btn-secondary btn-block">Third</button>
</div>

这是 JSFIDDLE .

推荐答案

如果您查看Bootstrap 4的文档，则应该这样做:

If you look at the documentation for Bootstrap 4, this is how you should do:

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous">


<div class="btn-group d-flex" role="group">
  <a href="#" class="btn btn-primary w-100">Apple</a>
  <a href="#" class="btn btn-primary w-100">Samsung</a>
  <a href="#" class="btn btn-primary w-100">Sony</a>
</div>

在此处查看文档: https://getbootstrap.com/docs/4.1/迁移/#button-group

已删除.btn-group-justified.作为替代，您可以将.w-100用作元素的包装.

Removed .btn-group-justified. As a replacement you can use as a wrapper around elements with .w-100.
