我有两个div，我希望彼此相邻。

Answer 1

将display: flex;添加到.row中

.test, .test2 {
  display: inline-block;
}
.row {display: flex;}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.2/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container">
 <div class="row">
 
<div class="test">
<button type="button" class="btn btn-success">Success</button></div>

<div class="test2">
   <span>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Soluta odit omnis maiores quis, tempore ut dolorum iure, nesciunt dolores laboriosam cumque praesentium blanditiis porro repellat numquam. Ducimus, dolores atque accusantium!
  </span>

Answer 2

由于你.test2 div上没有max-width或width属性，所以第二个div的宽度被视为屏幕宽度以表示文本。尝试将其中任何一个放在.test2上。它应该工作。

Answer 3

看来你正在使用bootstrap，所以使用bootstrap网格系统。我使用了col-sm-2和col-sm-10 classe，我已经删除了test和test2类

<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.1.1/css/bootstrap.css" rel="stylesheet"/>
<div class="container">
  <div class="row">

    <div class="col-sm-2">
      <button type="button" class="btn btn-success">Success</button></div>

    <div class="col-sm-10">
      <span>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Soluta odit omnis maiores quis, tempore ut dolorum iure, nesciunt dolores laboriosam cumque praesentium blanditiis porro repellat numquam. Ducimus, dolores atque accusantium!
      </span>
    </div>

  </div>
