This is awesome - thank you!

While the instructions are clear, I wasted a little time because I first forget the for the JS file, and then second - and even harder to figure out - I failed to add the for the CSS file.

If the Usage section added a brief reminder like the following, that could save folks some time:

"Add <link> tags for the JS and CSS files to the HTML file"

I recognize that folks working with HTML + JS + CSS every day would likely find this obvious.

Cheers! And thank you.

Great thanks for the suggestion. Step 2 specifically referenced the CSS file, but I can also have it reference the JS.
