Revealing module content on hover can have some helpful benefits.
1) It can be a great way to have a more compact or elegant design of your web page initially.

3) It can entice users to interact with your page.
4) It looks cool :). The basic idea is to show only a portion of the module content (like a teaser) which makes it enticing for visitors to hover over to see more. Once they do hover over the module, the entire content is revealed with a smooth hover effect that opens and closes like a shutter.
