How to make post preview when hovering over thumbnail?

Question

WordPress

Good day to all. If anyone can help a beginner - do not pass by) You need to do the following: the page contains previews (thumbnails) of a certain category, how to make it so that when you hover over a thumbnail (or rather a block with a thumbnail), a window of certain sizes appears (without reloading the page) in which there is already a full picture and not a thumbnail and an explanation, that is, roughly speaking, when you hover over the thumbnail, a window with a record appears (naturally, each thumbnail has its own record). And if not difficult, at least a little more. Thank you in advance!

Good afternoon.
Here's what you need: mentor-framework.ru/?p=216
You need to create a div with content in it, and then hide it and show it on click, hover.
In the example, there is no movement using Z-index, but it is better to add.
