I would like a pop up to appear on my website for a visitor who has never visited my site before. The main aim of the pop up is to get people to like the page on Facebook. With a Like button on it that directly links in with my company Facebook page. This should work on the homescreen as well as direct links to other pages that someone else has clicked on external to the site.
I want it so that it gracefully appears in the site with the background of the site turning translucent so the main attention is on the pop up.
Attached is a mockup of the pop up, as well as another mockup of how I want it to appear on the website.
Website is a shopify site: [url removed, login to view]
