Connecting jQuery

First, we need to download jQuery from the official site. Then put the resulting file in the folder with your site and connect it like this:

html<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title></title>
    <script src="path to file with jQuery"></script>
  </head>
  <body>
    
  </body>
</html>

Once connected, you can start writing code using this library.
