On Hover Move The Text Up

On Hover Move The Text Up

So I'm trying to move up the text when you hover over the image but I
can't seem to get it to work. I tried using :hover and then using
padding-bottom to move it up but it didn't work. So I basically want the
text "Nature" or "Bengal Tiger" to move up when you hover over the image.
Here's a pic that illustrates what I want to achieve.
