Unable to solve this-- Take a moment to read the code in the app.js file. The code should display a model or pop-over window (built with HTML). In the modal window there should be a place for a message to display and a button to dismiss or close the modal. Check out how the code runs in the preview. There's something wrong. The dismiss button isn't showing in the modal. Can you fix it?
//Create the Modal
var $modal = $("<div id='modal'></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 att it to modal
var $dismissButton = $("<button>Dismiss</button>");
//Hide modal when button is pressed
$dismissButton.click(function(){
$modal.hide(300);
});
$("body").append($modal);
//A function to show a modal
function displayModal(message) {
$placeHolder.text(message);
$modal.show();
}
//Show an example modal
displayModal("Hello World!");

var $dismissButton = $("<button>Dismiss</button>");
$modal.append($dismissButton);

5,735 PointsI did this a little different but it considered it incorrect. In a "real-world" scenario would this work?
var $dismissButton = $modal.append("<button>Dismiss</button>");
