Question

如果我将class="nav nav-pills"放在class="pull-right"之前，那么它就会工作。那么，我如何才能解决这个问题。

感谢您的帮助。这是我第一次学习Html :)）

Answer 1

您必须在同一个类标记中包含类名，如下所示：

 <ul  class="nav nav-pills pull-left" role="tablist" >

这种方式不会起作用

 <ul  class="pull-left" class="nav nav-pills" role="tablist" >

Answer 2

你应该这样做https://jsfiddle.net/2Lzo9vfc/153/

<强> HTML

<ul class="nav nav-pills pull-left" role="tablist" >
  <li><a href="rub1ck.php">About Us</a></li>  
  <li><a href="#">Expertise</a></li>
  <li><a href="#">work</a></li>
</ul>

<ul class="nav nav-pills pull-right" role="tablist" >
  <li><a href="#">Blog</a></li>
  <li><a href="#">Contact</a></li>
  <li><a href="login.php"class="btn btn-default" role="button" >Login</a></li>
</ul>

Answer 3

你可以试试这样的课吗

class =＆＃34; pull-left nav nav-pills＆＃34;

据我所知，不支持在同一标签中包含两个类属性...
