Answer 1

The correct way to use FontAwesome icons is: <i class="fas fa-map-marker"></i> (look at the final </i> tag).

In your case:

<li><span><i class="fa fa-map-marker"></i></span></li>
<li><span><i class="fa fa-phone"></i></span></li>
<li><span><i class="fa fa-envelope"></i></span></li>

Answer 2

The i tag should be closed.

<ul>
    <li><span><i class="fa fa-map-marker"></i></span></li>
    <li><span><i class="fa fa-phone"></i></span></li>
    <li><span><i class="fa fa-envelope"></i></span></li>
</ul>

The i tag is not an empty html tag nor a solidus tag and hence needs a closing tag
