I style the button, but it gives me an error.

I get this error: Bummer: Did you make a call to the "addClass" method after calling the "attr" method on the variable named "$submit"?

index.html 
<!DOCTYPE html>
<html lang="en">
<head>
    <title>Document</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <button type="submit" class="submit-btn">Submit If You Can</button>

    <script
    src="jquery-3.2.1.min.js"></script>
    <script src="app.js"></script>
</body>
</html>
app.js 
const $submit = $('.submit-btn');
$submit.attr('disabled', true);

$submit.addClass('disabled');

Your code has the same effect, but it wasn't done in the way specified by the challenge.

The instructions say, "Chain the appropriate jQuery method ...". Remember that chaining is when you call a method directly on the result of a previous call, so everything goes in one statement:

$submit.attr('disabled', true).addClass('disabled');
