I got the overlay to disappear but I have no idea what I'm doing

I can't figure out how to make the dismiss button appear

js/app.js 
//Create the Modal
var $modal = $("<div id='modal'>var $dismissButton = $("<button>Dismiss</button>");</div>");

//Create a placeholder for text in the modal
var $placeHolder = $("<p id='placeHolder'></p>");
$modal.append($placeHolder);

//Create a button to dismiss modal and add it to modal
var $dismissButton = $("<button>Dismiss</button>");

//Hide modal when button is pressed
$dismissButton.click(function($dismissButton){
  $modal.hide($modal);
});

$("body").append($modal);

//A function to show a modal
function displayModal(message) {
  $placeHolder.text(message);
  $modal.show();
}

//Show an example modal
displayModal("Hello World!");
index.html 
<!DOCTYPE html>
<html>
<head>
    <link rel="stylesheet" href="css/style.css" type="text/css" media="screen" title="no title" charset="utf-8">
    <title>Modal Example</title>
</head>
<body>
    <h1>Modal Example Page</h1>

    <script src="//code.jquery.com/jquery-1.11.0.min.js" type="text/javascript" charset="utf-8"></script>
    <script src="js/app.js" type="text/javascript" charset="utf-8"></script>
</body>
</html>

Hi there! So instead of giving a straight up solution, I'm going to give a hint. In the lines just above the creation of the dismiss button you have the creation of a $placeHolder variable. This is then appended to the modal.

Now, you have the creation of a $dismissButton variable. All that's left now is to append it to the modal. The same way it was done in the lines above :sparkles:
