For the link to Help section of the webpage, I am using <i class="fa fa-lg fa-question-circle"></i> for icon in the sticky footer of the webpage.
What fa-class should i use for the link to Forum?
回答1:
Usually we use these icons,
- commenting
- commenting-o
- comments
- comments-o
You can also build a custom icon by using set of icons available in the font-awesome icon set by stacking and aligning them accordingly.Stacked Icons
Here I designed something for you.You can use this as a forum icon.
<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css" rel="stylesheet"/>
<span class="fa-stack fa-lg">
<i class="fa fa-commenting-o fa-stack-1x" style="margin-left:12px;"></i>
<i class="fa fa-users fa-stack"></i>
