Use

The CSS3 properties discussed have not yet been adopted by the W3C, let alone been implemented by any browser vendor. If, and when, they are adopted, their syntax and functionality won't necessarily be as proposed. We've taken a look at them as an introduction to the Mozilla ones, which are implemented.

The Mozilla implementation is proprietary and meant for internal use. See your netscaperoot/res/forms.css for an example of this.

So, use these properties cautiously, without reliance.

Useless or Informative?

There are many more Mozilla proprietary properties. If you would like use to dicuss any more of them in the future, please let us know.
