Using the dollar sign is not recognized when creating a new variable

I need help figuring out how to create a scroll animation from the bottom in my code. When inspecting, I keep getting an error "$ is not defined". Here's the snippet:

var navopen = false;
function togglenav(){

    // Code for toggling navigation
}
// CSS styling

body{
  width: 100vw;
  height: 100vh;
  overflow-x: hidden;
}

// More styling...
<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>Piano Life</title>
    <link href="style.css" rel="stylesheet" type="text/css" />

    // Linking libraries and external resources
  </head>
  <body class="" id="body">
    <div id="navbar" onclick="togglenav();">
        <div id="line1"></div>
        <div id="line2"></div>
        <div id="line3"></div>
        
    </div>

    // More HTML content...

</body>
</html>
