Internet is full of boring popups. So, it’s a time to break this trend. That’s why I created “Layered Popups” (WordPress popups plugin). With this plugin you can realize your imagination and make unique multi-layers WordPress popup windows. You can create multiple layers with whatever-you-want content and add custom transitions/animations for each layer. You can embed AJAX-ed subscription/contact form which works with 29 email marketing providers.
