Problem with django-social-share

[sunday honesty]

Hello develops, hope you guys are doing well. Really thankful for all those who make out time to answer our varrying questions.

When I used django-social_share, everything worked fine until I added custom templates.
After creating the templates and styling with W3.CSS, the social link didn't display again... I deleted all the templates and again the link showed...
Can someone help me take a look at my teplates to help determine what I have done wrong.

<span class="W3-badge W3-hover-blue facebook-this">
<a href="{{ facebook_url }} class="W3-xlarge" target="_blank" title="Share to Facebook">li class="fa fa-facebook"></li>
</span>
