fontawsome中条形图和条形图o之间有什么区别

Question

在网站http://fontawesome.io/icons/中有条形图和条形图o（别名）图标 但是当点击查看说明时，它会转到同一页面url，所以有什么区别。

C:\Users\mech10>cd superlists

C:\Users\mech10\superlists>python manage.py test
Creating test database for alias 'default'...

没有区别，它只是一个别名！请参阅以下示例，使用两个CSS类：

＆＃13;

＆＃13;

<link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.6.3/css/font-awesome.css" rel="stylesheet"/>
<i class="fa fa-bar-chart" aria-hidden="true"></i>
<i class="fa fa-bar-chart-o" aria-hidden="true"></i>

＆＃13;
