Border on a side menu?

I've got a wordpress blog, www.gareth-bale.net

Now at the side on the menu I have a Gareth Bale Facts part and want to put a black border round the facts.

What sort of coding would I need to use, any ideas?

Thanks

 

add on style.css

#FactBox{
border: 1px solid #000; 
}

Code (markup):

 

Thanks, thats worked a treat
