Super Simple CSS3 Only Bookmark Ribbons

Here are some extremely easy basic CSS 3 only triangular-bottomed bookmark split-ribbon things.
This is accomplished through some creative use of the "border" attribute on divs in CSS. It takes a main div (where the body of the ribbon is) and then two smaller divs that create the actual split ribbon effect.
You can change their color, or even assign a background image for some truly ribbon like effects.
You could probably even throw some nice shadows on it and make it look even better, but, this is just a very simple basic version.

I whipped these up today for something I was working on and realized it was worth sharing with the world.
Thanks to CSS-Tricks.com for the basis of this effect (css triangles).
