No, unfortunately not. I've encountered that before: You can't add HTML to nav items on cover pages or into the name of a button for a lightbox form, either. Its just the way the system's put together.

I think the retina displays on the newer large are messing this up. Is 667px the number to use to replace 550px to account for that? Or is another number better? I think 667 is the number to use for the width on an iPhone 6/7 and 736 for the 6+/7+. Per https://www.paintcodeapp.com/news/ultimate-guide-to-iphone-resolutions

Yes, it does.

Note that in @cstine's answer above, there's a stray back-tick (aka grave accent mark) at the end of the line of code. If you paste that character into the Code Injection box it can cause problems. Here's the code without that character for easy copy-pasta: <link href="//maxcdn.bootstrapcdn.com/font-awesome/4.2.0/css/font-awesome.min.css" rel="stylesheet"> I've also found that you can change the 4.2.0 numbers to a newer version of Font Awesome to access the new icons. E.G.: <link href="//maxcdn.bootstrapcdn.com/font-awesome/4.4.0/css/font-awesome.min.css" rel="stylesheet"> or <link href="//maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet">
