In response to several requests the above demonstration is of a number pad with CIRCULAR links.
These links are just a styled unordered list.
The links only occupy the circular pads and will not be selectable until the mouse pointer is actually on the pads.
No images have been used in the making of this demo, just an excessive amount of extra markup ;o) .
I would not advocate using this method for circular links, but it does show what is possible and that links do not have to be rectangular.
You may use this method on your personal 'non-profit' web site without seeking my permission. A link back to CSSplay is always appreciated.
Commercial usage is also permitted without seeking approval, but I would ask that a donation is considered to support my work on CSSPlay.
If you are having problems integrating any of my demonstrations into your website then I now offer a service to fault find and correct any errors that you may have introduced. Please email me for more information.
