Answer 1

將clearfix添加到page-header

<div class="page-header clearfix">

 <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" /> <div class="container"> <div class="page-header clearfix "> <h2>Header</h2> <div class="btn-group <!-- pull-right -->"> <a class="btn btn-success" href="/Scope/New">Create</a> <div class="btn-group"> <button type="button" class="btn btn-success dropdown-toggle" data-toggle="dropdown"> <span class="caret"></span> </button> <ul class="dropdown-menu pre-scrollable" role="menu"> <li class="dropdown-header">Create as copy: </li> <li><a href="/Scope/New/1">Test 1</a></li> <li><a href="/Scope/New/2">Test 45</a></li> <li><a href="/Scope/New/3">Lorem ipsum</a></li> </ul> </div> </div> </div> </div> 

Answer 2

在page-header添加clearfix ，還添加display: inline; 到h2 。
這樣可以解決您的問題。 （當前h2內聯添加的，您可以將其放在CSS文件中）

 <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" /> <div class="container"> <div class="page-header clearfix "> <h2 style="display: inline;">Header</h2> <div class="btn-group <!-- pull-right -->"> <a class="btn btn-success" href="/Scope/New">Create</a> <div class="btn-group"> <button type="button" class="btn btn-success dropdown-toggle" data-toggle="dropdown"> <span class="caret"></span> </button> <ul class="dropdown-menu pre-scrollable" role="menu"> <li class="dropdown-header">Create as copy: </li> <li><a href="/Scope/New/1">Test 1</a></li> <li><a href="/Scope/New/2">Test 45</a></li> <li><a href="/Scope/New/3">Lorem ipsum</a></li> </ul> </div> </div> </div> </div> 

Answer 3

 .page-header { padding-bottom: 9px; margin: 40px 0 20px; border-bottom: 1px solid #eee; display: flex; align-items: center; justify-content: space-between; } 

  <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" /> <div class="container"> <div class="page-header"> <h2>Header</h2> <div class="btn-group"> <a class="btn btn-success" href="/Scope/New">Create</a> <div class="btn-group"> <button type="button" class="btn btn-success dropdown-toggle" data-toggle="dropdown"> <span class="caret"></span> </button> <ul class="dropdown-menu pre-scrollable" role="menu"> <li class="dropdown-header">Create as copy: </li> <li><a href="/Scope/New/1">Test 1</a></li> <li><a href="/Scope/New/2">Test 45</a></li> <li><a href="/Scope/New/3">Lorem ipsum</a></li> </ul> </div> </div> </div> </div> 

就是這樣，您可以使用flex。
