I'm not trying to be rude or unappreciative, but it's kinda crazy to me that the website itself doesn't contain the demo of the thing? I see sample code to implement it on my own site, but the site itself doesn't seem to have any highlighting or I highlighted some text and didn't see anything unusual? Maybe it's just me, maybe I'm missing something here? I'd like to see an example of what a thing does before straight up installing the code on my website.
