Hi Treehouse
I've always struggled to get to grips with the new CSS3 border-image property. I've been looking through the library and can't find anything relating to the technique.
http://www.w3schools.com/cssref/css3_pr_border-image.asp
Is there a tutorial or deepdive available on the subject?
Many thanks Dan

Exactly what I was looking for, just used it on a stage site and it works a charm!

Next, you need to specify the image you want as a border, using its url()
Finally, you need to specify the width, height and if you want to stretch, or repeat ( use round) the image that you're using for the border.
border-image: url(/* Image url */) 30 40 stretch;
The first number (30) refers to the width The second number (40) refers to the height
When you are done, your syntax should look something like this:
-webkit-border-image:url(/* Image url */) 30 40 /*styling the image*/; /* Safari 5 */
-o-border-image:url(/* Image url */) 30 40 /*styling the image*/; /* Opera */
I hope this will help you.
