This is an example of Simp Modal Window WordPress Plugin, in this example i am displaying facebook like box, the like box will be displayed once, revisit again after 6 hours to see it again or alternatively delete cookie from your browser to see it again in action.
why it’s, because i have enabled cookie for this facebook like box modal (popup) and set expiry value for 6 hours, when you’ve visit this page facebook like box was displayed to you, now refresh the page the like box will not shown untill cookie will be expired or deleted from your browser.
Simp Modal WordPress plugin has ton of settings, which you can customize to your specific needs, you can control the popup where to display, when to display and how to display everything is highly customizable from popup creation/editing screen.
