Create Leaving Screen using JQuery

You will create a Leaving screen using Jquery that prompts a user to consider an offer before leaving a website. When a user closes the browser the website is dimmed and a leaving screen is shown centered in the middle of the page. When a user navigates to a website that is not the current website or if the user wants to close the browser, then the leaving screen is shown. The leaving screen will NOT be a javascript confirm box or a javascript alert box. You will implement a leaving screen that displays an HTML web page centered in the middle of the screen with the background dimmed. The desired size of the centered leaving screen is 450 by 450 pixels in size and this value should be configurable. The entire design for this project is included in the attached pdf file. THIS SOLUTION MUST WORK WITH POPUP BLOCKING TURNED ON IN THE BROWSER. ## Deliverables Your deliverable will be a php file with the specified functionality.
