make-footer-styling

[oreyes1991]

in the footer there's a secction call foot-socials
css:
.foot-socials { display: grid; grid-template-columns: 4em 4em 4em; place-self: center; }

the idea is to make each feel like can be clicked

TASK:

1. make the cursor to display the hand when is hover insted of the dafault cursor.
2. make the some sort of style change when you hovered, like "background-color", "box-shadow"
   OPTIONAL:
   1. make a transition with the hover change style, like fade in or fade out

HINT:
each one has a class = 'icon-round'
