Did anyone already designed checkboxes with font awesome 5 icons inside?
I've already googled it and found only examples for FA-4 like http://flatlogic.github.io/awesome-bootstrap-checkbox/demo/
I updated to FA5 and got other things with CSS pseudo elements to run, but inside a checkbox it's not running. I'm open to other solutions without pseudo elements.
Thanks in advance!
Fiddle-Examples:
/* Checkboxes */
.checkbox input[type="checkbox"] {
  display: none;
}
.checkbox label {
  padding-left: 0;
}
.checkbox label:before {
  content: "";
  width: 20px;
  height: 20px;
  display: inline-block;
  vertical-align: bottom;
  margin-right: 10px;
  line-height: 20px;
  text-align: center;
  border: 1px solid #ccc;
  box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
  font-family: "FontAwesome";
}
.checkbox input[type="checkbox"]:checked+label::before {
  content: "\f00c";
