While this is added to the bbc list, it needs a little explanation
you can add font awesome icons in posts
you can search their library for icons :
Font Awesomeon their site you will see a code
<i class="fas fa-kaaba"></i>
you will want just the inside part
so delete the
<i class="
keep the
fas fa-kaaba
and delete the
"></i>
there are two buttons in the formatting list
![]()
(eventually I will make these two look different)
the first one says "Insert Font Aweasome BBC" this is the button most will use
it will input
[fa][/fa]
into the post, now the above part that you kept you will add between those tags
[fa]fas fa-kaaba[/fa]
and there you go

here's a few other examples
[fa]fab fa-facebook-f[/fa]
[fa]far fa-keyboard[/fa]
now the second button will say "Insert Layered Font Aweasome BBC"
you can layer icons and color them
this one is a bit more tricky
when you click on the button it will insert into the post
[fasi][/fasi]
just as above you would put the part that you kept between the tags
however to layer it with another icon and to color it you need to change the tag a bit by adding a= b= c=
[fasi a=fas fa-stop b=white c=red]fas fa-kaaba[/fasi]
so a is the background icon
b is the background color
c is the foreground color
and the icon between the [fasi] tags is the foreground icon
you can have some fun making your posts and articles stand out
