-moz-outline-radius

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

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.

Initial value as each of the properties of the shorthand:
Applies to all elements
Inherited no
Percentages as each of the properties of the shorthand:
Media visual
Computed value as each of the properties of the shorthand:
Animatable as each of the properties of the shorthand:
Canonical order the unique non-ambiguous order defined by the formal grammar

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
