Problem in loading icons

I suggest adding this line in the header section:

```
<head>
  <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">
</head>
```

as the icons didn't appear in my browsers (tried Edge & Firefox).
Any way a huge Thank U for this nice template.
