I have incorporated remote resources such as jQuery and icons by linking them like this:
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
My concern is whether these resources will still function if there is no internet connection available. This is crucial for my presentation because I will need to open local .html files without guaranteed internet access. I am worried that functions and icons referenced from online libraries might not work in such situations.
