wordpress - 为二十十二主题添加丝带包装

Question

我想在我的页面左侧添加一个功能区。我正在使用 word press 这个伟大的平台。具体来说，二十二模板。我进入代码并在 themes/twentytwelve/style.css & themes/twentytwelve/header.php 下进行编辑。问题是它仅以纯文本形式显示在右侧。 Css 没有做任何事情。这是我试图在 wp 主题中完成的:http://jsfiddle.net/H6rQ6/9448/

ribbon- themes/twentytwelve/style.css 的 CSS

与fiddle相比，CSS中没有.wrapper规则；但是指向 Wordpress 版本的链接将有助于了解这里出了什么问题。
