I've been trying to do the following in my .hbs file:
<div class="nav-avatar" style="background-image: url('\{{ url }}avatar/\{{ user.pic }}');"></div>
However the CSS when looking through the website looks as so:
<div class="nav-avatar" style="background-image: url('avatar/');"></div>
Both {{ url }} and {{ user.pic }} display as they should otherwise.
