## Validation Error: CSS Definition

### Error: Property XXX does not exist in this definition

The property specified is not valid within a specific CSS version or implementation, such as CSS1 or Netscape 4.x. In most cases this will simply mean that the property will not have an effect in browsers that don't support it. Be aware, however, that in some cases an unknown property may cause IE 3.x or Netscape 4.x browsers to process the rest of the style sheet incompletely.
