Employee facebook logo to linked in not working!

Hi!!!

I tried this CSS Code before and it worked magically but I don’t know what happened the magic stopped working :(((. Anyone can help me?

Here is the CSS code I copied from other post and suddenly stop working
.team-social .fa-facebook::before {
content: ‘f0e1’;
}

Here is the link to my website. If you see the employee section, bottom of the home page, http://www.promentors.us.com/
it shows the ‘f0e1’ rather than the linkedin icon… why that happened?

Hi,

It’s content: ‘\f0e1’;. You’re missing the </code>.

Hi Vlad,

I tried to add \ to my code, but after I save the code, \ is gone and the linkedin icon is still not here.
