What is $(’.btn-undo’) ? The dollar sign and the dot are a bit confusing. Is the dot-string a string to be used in HTML? What about the dollar sign, how does it fit in? -=Thank you.
That’s jQuery, and it selects all elements that have the CSS class btn-undo.
Ah! OK. That makes since . Its been a while since I took the CSS Front end, and I haven’t taken the jQuery course yet. Looks like it is 2 courses away. Thank you for the helpful, quick response.
