I am trying to check if Ads are visible or not(blocked) when user loads my web-application page, if not show a message, which is already hidden by default,so how can I detect if an element is visible in the current page after loading it, and if is not-visible make it visible(some other div to show user's a message to load ads on my website and support us) using jQuery or javascript?

Also is it possible to toggle the visibility of an element, using the function toggle() or any other function?
