Font awesome not working in footer

1

I added some font awesome(latest versioon) badge (twitter, github and codepen) in footer, but somehow not working and get square shape instead of badge.
This is my code…

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">
<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.8.1/css/all.css" integrity="sha384-50oBUHEmvpQ+1lW4y57PTFmhCaXp0ML5d60M1M7uH2+nqUivzIebhndOJK28anvf" crossorigin="anonymous">

            <i class="fa fa-twitter" aria-hidden="true" style="font-size: 26px;"></i>
            <i class="fa fa-github" aria-hidden="true" style="font-size: 26px;"></i>
            <i class="fa fa-codepen" aria-hidden="true" style="font-size: 26px;"></i>
            
        </div>

Make them:

<i class="fab fa-twitter" style="font-size: 26px;"></i>
<i class="fab fa-github" style="font-size: 26px;"></i>
<i class="fab fa-codepen" style="font-size: 26px;"></i>
