I imagine most of the web dev world hadn't realized that the display module of CSS3 was only in working draft status. There are some serious improvements and equally serious issues involved with this seemingly innocuous property.

We have reached 10 years old, a fair age for any website. Actually the domain was registered in October 2002, the site started with the CSS Generator and I added the forum in March 2003.

Before you post please consider something. We, that is the people that make tech forums like this one viable and useful for the community, keep them alive and provide a little of our experience, and time for free, really do not appreciate people taking advantage of them for what they think is possibly useful SEO gaming, we have to deal with the threads created, wasting our time and more importantly taking the time we may spend helping someone with a genuine need and chucking it away dealing with the utter drivel you post.

Border-image enables the use of images as borders. It overrides the border-style property which can act as a fallback if the image is unavailable or border-image in not supported.
Border-image is shorthand for the following properties with there initial values:
The image can be sliced using 4 length values: top, right, bottom, left. Which creates a grid of 9 areas, the 4 corners, 4 sides and the center which is unused.
