twitter-bootstrap：如何在一行中对齐引导选项卡

时间：2016-08-27 04:34:14

标签： html css twitter-bootstrap twitter-bootstrap-3

以下是我的标签菜单enter image description here

的屏幕截图

但是如果标签菜单项有更多项

，它会跳转到下一行

代码 

<div class="row col-lg-12">
    <ul class="nav nav-tabs">
            <li class="active"><a data-toggle="tab" href="#home">Home</a></li>
            <li><a data-toggle="tab" href="#menu1">Menu 1</a></li>
           ......
    </ul>
    <div class="tab-content">
      <!--Contents goes here -->
     </div>
  </div>

那么我怎样才能将所有的memu项目整合到一行？

您正在寻找的是我们称之为可滚动的选项卡式菜单，您可以通过该菜单单击左/右箭头来浏览多个选项卡。您将需要使用jQuery和CSS来实现此目的。这是一个很好的例子。希望它是你所追求的。

您可以将其扩展为所需的列数。它需要添加 less 功能。

less变量允许在grid.less文件中设置列宽：

@grid-columns:              12;

这是一个我发现有用的代码，可以将它扩展到18列：

//
// Grid system
// --------------------------------------------------

// Set the container width, and override it for fixed navbars in media queries
.container {
  .container-fixed();
}

// mobile first defaults
.row {
  .make-row();
}
