Post Preview when mouse over Link?

Hi,

I set up a website on North Korea news on wordpress – https://www.nknews.org

I am using the ‘Category Show’ plugin to dynamically create the headlines on the front page. When I post new stories to the site, Category Show puts their headlines on the main page as you can see.

The thing is, I want users to be able to hover their mouse over any given headline and a popup preview box comes up with an excerpt of the post – so they can decide if they want to click it or not. Kind of like Snapshots I guess, but only on the homepage – and not as cumbersome as snapshots (i.e just txt only)

Is this possible?

Thanks!
