using border-radius


Prompted by a recent comment I give you my CSS version of Fibonacci's spiral (and no, I hadn't heard of it either). But here it is, produced by using just four quadrants of a circle images and sizes in ems so that it will scale up and down with text sizes.

1st July 2005

My pure CSS version using no graphics (but a bit chunky) added. This used em size containers and percentage size 'curves'.

31st August 2009

Moz border radius version updated to add a decreasing border width as suggested by Christopher Robert Jaquez.
