Question

我一直在尝试将搜索栏和提交按钮放在同一行的表单中，方法是为它们分配不同的引导列长度，但表单标签拒绝允许这样做。

使用display:flex

创建包含新类的div的简单方法

.flex{
  display:flex;
}

<html lang="en">

    <!-- Required meta tags -->

代替创建一个全新的类，您可以选择使用Bootstrap的内置框架来处理表单。根据您使用的Bootstrap的特定版本，您可以依赖.input-group-addon或.input-group-append：

＆＃13;

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.3/css/bootstrap.min.css" integrity="sha384-Zug+QiDoJOrZ5t4lssLdxGhVrurbmBWopoEl+M6BdEfwnCJZtKxi1KgxUyJq13dy" crossorigin="anonymous">

<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.9/umd/popper.min.js" integrity="sha384-ApNbgh9B+Y1QKtv3Rn7W3mgPxhU9K/ScQsAP7hUibX39j7fakFPskvXusvfa0b4Q" crossorigin="anonymous"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.3/js/bootstrap.min.js" integrity="sha384-a5N7Y/aK3qNeh15eJKGWxsqtnX/wWdSZSKp+81YjTmS15nvnvxKHuzaWwXHDli+4" crossorigin="anonymous"></script>


<form method="post">

<div class="input-group">
	<input type="text" class="form-control" placeholder="Ex: WRT 102" />
	<div class="input-group-append">
       <button type="submit" class="btn btn-secondary">Submit</button>
	</div>
</div>

</form>

注意：您可以替换＆＃39;提交＆＃39;使用Font Awesome图标，但您可能需要应用其他样式以确保按钮高度保持正确排列。我相信这是最新版本的Bootstrap 4（beta 3）中的一个错误。
