-moz-outline-radius - CSS: Cascading Style Sheets 编辑

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 shorthand property can be used to give an element's outline rounded corners.

/* 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;

Constituent properties

This property is a shorthand for the following CSS properties:

• -moz-outline-radius-bottomleft
• -moz-outline-radius-bottomright
• -moz-outline-radius-topleft
• -moz-outline-radius-topright

Syntax

Values

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.
