The Mozilla border radius properties differ significantly from those outlined in the CSS3 proposal:

1. There is no way to specify different values for horizontal and vertical radii.

2. The base property, -moz-border-radius, accepts up to four values.

3. The corner-specific properties accept only a single value.

4. Besides length units, all properties accept the "inherit" value. This is a standard CSS property value that reflects the value set for the property in a parent, containing element.

The table below illustrates the results to expect when using -moz-border-radius:

-moz-border-radius:<length value>;

If one value is specified, then all four corners are affected. The horizontal radius and the vertical radius will be identical.

Mozilla CSS Syntax: -moz-border-radius:55px; Mozilla JS Syntax: element.style.MozBorderRadius="55px";

-moz-border-radius:<length value> <length value>;

If two values are specified, the first one affects the top-left and bottom-right corners. The second affects the top-right and bottom-left corners.

Mozilla CSS Syntax: -moz-border-radius:55px 19px; Mozilla JS Syntax: element.style.MozBorderRadius="55px 19px";

-moz-border-radius:<length value> <length value> <length value>;

If three values are specified, the first one affects the top-left corner. The second affects the top-right and bottom-left corners. The third affects the bottom-right corner.

Mozilla CSS Syntax: -moz-border-radius:55px 19px 40px; Mozilla JS Syntax: element.style.MozBorderRadius="55px 19px 40px";

-moz-border-radius:<length value> <length value> <length value> <length value>;

If four values are specified, the first one affects the top-left corner. The second affects the top-right corner. The third affects the bottom-right corner. The fourth affects the bottom-left corner.

Mozilla CSS Syntax: -moz-border-radius:55px 19px 40px 30px; Mozilla JS Syntax: element.style.MozBorderRadius="55px 19px 40px 30px";

The corner-specific properties are not as complicated.
