FontAwesome to template Ares after upgrading to 5.0

[RogerK]

With Elxis version 4.5 I  load to the template using the font FontAwesome with $eDoc->addFontAwesome() on function createTPL .
After upgrading to Elxis 5.0 fonts does not display the icons.
What do I need to add to the template to work properly?
what is the path to a new library?
Also, the template Ares needs an upgrade to be compatible with Elxis 5.0

Elxis 5.x uses fontawesome 5. However it is backwards compatible to fontawesome 4. Problems may exist when you display the fonts with CSS using pdeudo-elements.

Example 1
Fontawesome 4:
<i class="fa fa-camera"></i>
Fontawesome 5:
<i class="fas fa-camera"></i>

You will not have problem with the above code for fontawesome 4 in Elxis 5.x because there is backwards compatibility.

Example 2
Fontawesome 4:
.something::before { font-family: "FontAwesome"; font-weight: 900; content: "\f030"; }
Fontawesome 5:
.something::before { font-family: "Font Awesome 5 Free"; font-weight: 900; content: "\f030"; }

You will have problem with the above code for fontawesome 4 in Elxis 5.x because there is no "Fontawesome" font anymore. The correct font-family name is "Font Awesome 5 Free". So, in this case you must edit your css file and change "FontAwesome" to "Font Awesome 5 Free". Also, in some rare cases, the unicode code (here f030) has been changed.

Thank you very much datahell.
I'll try your tips immediately. I already saw in your new template five exactly what you are telling me and I will change what I need.

I found that:
The new version of Font Awesome also requires font-weight: 900; when you use solid icons in custom css classes.
The unicode entrypoint \f005 works without font-weight because it represents a regular icon with a font-weight value of 400.

I love when users do some research by themselves. Good job Roger!

I feel exactly the same! Bravo @RogerK!
