Summary

In Mozilla applications like Firefox, the -moz-outline-radius CSS property can be used to give outlines rounded corners. An outline is a line that is drawn around elements, outside the border edge, to make the element stand out.

-moz-outline-radius is a convenient shortcut to set the four properties -moz-outline-radius-topleft, -moz-outline-radius-topright, -moz-outline-radius-bottomright and -moz-outline-radius-bottomleft.

Syntax

/* One value */
-moz-outline-radius: 25px;

/* Two values */
-moz-outline-radius: 25px 1em;

/* Three values */
-moz-outline-radius: 25px 1em 12%;

/* Four values */
-moz-outline-radius: 25px 1em 12% 4mm;

/* Global values */
-moz-outline-radius: inherit;
-moz-outline-radius: initial;
-moz-outline-radius: unset;

Values

Elliptical outlines and <percentage> values follow the syntax described in border-radius.

One, two, three or four <outline-radius> values, represents one of:

<length>
See <length> for possible values.
<percentage>
A <percentage>; see border-radius for details.
  • If a single value is set, it applies to all 4 corners.
  • If two values are set, the first one applies to the top-left and bottom-right corners and the second one to the top-right and bottom-left corners.
  • If three values are set, the first one applies to the top-Left corner, the second one to the top-right and bottom-left corners and the third one to the bottom-right corner.
  • If four values are set, the first one applies to the top-left corner, the second one to the top-right corner, the third one to the bottom-right corner and the fourth one to the bottom-left corner.

Formal syntax

<outline-radius>{1,4} [ / <outline-radius>{1,4}]?

Example

HTML

<style>
p {
border: 1px solid black; 
outline: dotted red; -moz-outline-radius: 12% 1em 25px;
}

<head> <style>
p1 {
border: 1px solid black; outline: dotted red; 
-moz-outline-radius-topleft: 12%; 
-moz-outline-radius-topright: 1em; 
-moz-outline-radius-bottomright: 35px;
