This is a contributed (third party) filter for Moodle written by Julian (Moodleman) Ridden and shared on Moodle.org
Font Awesome provides sites with scalable vector icons that can instantly be customized — size, color, drop shadow, and anything that can be done with the power of CSS. Font Awesome is fully open source and is GPL compatible. No attribution is required when using the fonts although the project does say it is appreciated.
This filter makes it easy to add FontAwesome icons to course content in any FontAwesome enabled moodle site. Please be sure to target any questions related to this filter in the General Plugins forums at moodle.org and bugs to the GitHub Issue Tracker
The aim of this filter was to provide an easy and functional way for content creators to easily add FontAwesome icons anywhere in course content. If using the recommended method provide by FontAwesome which involves creating custom classes you will find that the text editor strips these out automatically as unrecognised/bad code. This filter provides another mechanism to add FontAwesome icons that won't be stripped out by the editor.
Enabling FontAwesome in Moodle
FontAwesom icon's will not work just by adding this filter to your Moodle. The filter just facilitates adding them to content. You will need to first ensure your site has the FontAwesome font enabled before you can use this filter. You can get FontAwesome running one of two ways.
Install/Use a FontAwesome enabled theme
Some Moodle themes are now coming with FontAwesome already enabled (e.g. Moodle Boost core theme). To find out if they do just read the information found about them in the Modules and Plugins Database.
One such theme that already has FontAwesome contained within is the Essential Theme by Julian Ridden.
Load FontAwesome via CDN
A content delivery network or content distribution network (CDN) is a large distributed system of servers deployed in multiple data centers across the Internet. The goal of a CDN is to serve content to end-users with high availability and high performance. You can pull FontAwesome into your site using any theme by adding a single line to your Admin settings. This line will connect to a dedicated CDN to reliably load FontAwesome into your moodle site.
To add the CDN to your Moodle you need to add the following line to your "Additional HTML" settings in Site Administration. You can find this located under the "Appearance" menu.
Once you are in the "Additional HTML" settings we need to add the following line to the "Within HEAD" section. This will then load the FontAwesome as part of every page load.
<link href="//netdna.bootstrapcdn.com/font-awesome/3.2.1/css/font-awesome.min.css" rel="stylesheet">
It should look like the image below. Once done you are now ready to use the FontAwesome filter.
Adding an icon
Adding an icon to anywhere in your course that you wish is now a simple process. The hardest part is finding the icon you wish to use. To browse the full list of over 360 icons please visit [this link]. Once you have found the icon you are after you just have to surround it with a set of square brackets. e.g.:
If you have typed in the icon name correctly you will see the icon appear once you have hit save.
If you wish to make the icon larger you can use a multiplier. e.g.:
[fa-camera-retro fa-2x] or [fa-camera-retro fa-4x]
If you wish to rotate the icon you can specify how many degrees clockwise. e.g.:
You can also flip an icon horizontally or vertically. e.g.:
[fa-camera-retro fa-flip-horizontal] or [fa-camera-retro fa-flip-vertical]
You can mute the colour to a dull grey. e.g.:
You can "pull" the icon to the left or right. If it is "pulled" to the left text will wrap to the right. e.g.:
All the settings above can be mixed and matched. For example if I was to type in:
[fa-quote-left fa-4x pull-left fa-muted]
Use a few of the new styles together, and you've got easy pull quotes or a great introductory article image. Or spinning icons for loading and refreshing content. Or fun big icons in multi-line buttons. You can combine all of them in any combination to get lots of new possibilities.
