Hi,
You can integrate FontAwesome 6 to template with this way:
1) Download the latest version of Font Awesome from its official site: https://fontawesome.com/download >> select the version for web and download the package
2) Unzip the downloaded package to this folder of template: root/templates/purity_iii/fonts/
For example, I download the free version for web and after unzip, I have folder: 'fontawesome-free-6.4.0-web', copy to template and rename to:
root/templates/purity_iii/fonts/font-awesome-6/ (just for easier recognization)
Now you load into template by opening the XML file: root/templates/purity_iii/etc/assets.xml
Put this line:
<file>fonts/font-awesome-6/css/all.css</file>
under stylesheets tag:
Now you can use new icons from FontAwesome 6.
Hope this helps.
