Make featured post side by side in widget bar

Hi!

I am working with a child theme of twenty twelve theme and am trying to customize the Advanced Featured Post Widget. I would like it to look exactly like this, with the underlined title, bold blue font underneath, and have two articles side by side:

How would I do this? My website is http://betterhousekeeper.com/

Thanks!
