The $ symbol is used by the jquery library. You should review the basics of HTML and write a proper structure of your document, using correct tags for head, script and body. If you use a correct source for the jquery script, it works. <html> <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.7.1/jquery.min.js"> </script> </head> <body> ... </body> </html>
