Hello everyone,
I want to change the icons for social network, I tried to change the class in “_includes/ svg-icons.html” and it does not work.
I want to make twitter icon like this:
https://fontawesome.com/icons/twitter?style=brands
you can check the repo here:
appreciate your help. 
Good day
Yes you’ll use the snippet provided
<i class="fab fa-twitter"></i>
And you’ll also have to make sure fontawesome CSS gets loaded in your head includes file or a layout. Their website should have instructions.
It might even be available as part of a Jekyll theme, such as jekyll-bulma which I use.
Finally, make sure you match the font awesome version. If you use font awesome v3 then v4 icons won’t work.
Here a tutorial for adding and using Font Awesome in a project
Thank you
I tried to change the class name but it doesn’t work.
how can I know which version I used in font awesome?
Did you add the link tag I recommended for fontawesome to your index.html? Ideally use the latest version 5.0.0 instead of 4.7
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.0.0/css/font-awesome.min.css">
You must add that before the class will work
Here is another reference
Thank you. I will try it.
