I am using Font Awesome Free 5.5.0 and define icon in css, like this.
.nav-side-menu li :not(collapsed) .arrow:before {
content: "\f007";
font-family: "Font Awesome 5 Free";
display: inline-block;
padding-left: 10px;
padding-right: 10px;
vertical-align: middle;
float: right;
}
it works fine, but just for few icons. I need to use this one, with code "f107". But this code doesn´t work. I can find this code even in my linked font-awesom file in project, with same class name as in documentation, but when i use it in css, nothing happend.
