[jQuery] use of jquery to change existing code


Hello,
I am trying to add an effect to my existing JS. Not an expert with JS
by any means, I can manage to work my way around is most instances. I
have jquery library called in my code because of a password strength
meter so I might as well try and utilize it's functions.
My code:
if(value=="UK"){
document.getElementById('vat').style.display='block';}
This is changing a div id=vat with style=display:none to
display:block; as you can see. I'd like that to fade in. Checked out
Cody's examples but can't figure out how to impliment. Can anyone
help?
Thanks
