我正在尝试为块式主导航创建 css 功能区，但是当我包含“display：table;”时，功能区的右侧三角形不起作用 或“显示：块；” 在 Clearfix 中。自然，当我删除 Clearfix 时，色带可以正常工作，但包裹消失了。让功能区工作并使用 Clearfix 来防止包装折叠会很棒。任何提示将非常感谢！

可以在这里找到原始代码和我的工作所基于的图像：http: //jsfiddle.net/necolas/xCfeH/

这是我编写的 HTML：

<!DOCTYPE html>

  <html>

    <head>

      <meta charset='UTF-8' />

      <link rel='stylesheet' href='css/style.css' />

    </head>

    <body>

      <div id="page-wrap" class="group">

        <nav id="main-navigation">

           <ul id="ribbon">

               <li><a href="#">ABOUT</a></li>

               <li><a href="#">CLIENTS</a></li>

               <li><a href="#">SERVICES</a></li>

               <li><a href="#">CONTACT</a></li>

           </ul>

        </nav>

      </div> <!-- END page-wrap -->

   </body>

这是CSS：

/*
Description: Ribbon Block Nav Ribbon
*/


/* Clearfix to prevent collapse of bottom body area when divided into two.
------------------------------------------------------------ */
.group:after { content:""; display: table; clear:both;
}

要清除浮动，请尝试添加overflow: hidden到容器中。

任何一个：

#ribbon { overflow: hidden; }

或者：

#main-navigation { overflow:hidden; }

（并简单地省略clearfix类）

问题解决如下：“将#ribbon更改为”position：absolute;”并将“position：relative;”添加到#main-navigation以进行修复。
