Is there a way to make a shape like the following using only CSS.

I am a newbie so I really don't know much, and I've been googling for hours but nothing. Oh and I found this link http://www.css3shapes.com/ but I don't know how to use the codes there to make the above shape and this too http://jsfiddle.net/JvdKk/ Oh and the borders are 3pt in word.
