perspective-origin

Summary

The perspective-origin CSS property determines the position the viewer is looking at. It is used as the vanishing point by the perspective property.

Syntax

perspective-origin: x-position;              /* one-value syntax */
perspective-origin: x-position y-position;   /* two-value syntax */

/* When both x-position and y-position are keywords, the following is also valid */
perspective-origin: y-position x-position;

/* Global values */
perspective-origin: inherit;
perspective-origin: initial;
perspective-origin: unset;

Values

x-position

Indicates the position of the abscissa of the vanishing point. It can have one of the following values:

• <length-percentage> indicating the position as an absolute length value or relative to the width of the element. The value may be negative.
• left, a keyword being a shortcut for the 0 length value.
• center, a keyword being a shortcut for the 50% percentage value.
• right, a keyword being a shortcut for the 100% percentage value.

y-position

Indicates the position of the ordinate of the vanishing point. It can have one of the following values:

• <length-percentage> indicating the position as an absolute length value or relative to the height of the element. The value may be negative.
• top, a keyword being a shortcut for the 0 length value.
• center, a keyword being a shortcut for the 50% percentage value.
• bottom, a keyword being a shortcut for the 100% percentage value.

Formal syntax

<position>
where 
<position> = [[ left | center | right | top | bottom | <length-percentage> ] | [ left | center | right | <length-percentage> ] [ top | center | bottom | <length-percentage> ] | [ center | [ left | right ] <length-percentage>? ] && [ center | [ top | bottom ] <length-percentage>? ]]
where 
<length-percentage> = <length> | <percentage>

Browser compatibility

[1] In addition to the unprefixed support, Gecko 45.0 (Firefox 45.0 / Thunderbird 45.0 / SeaMonkey 2.42) added support for a -webkit prefixed version of the property for web compatibility reasons behind the preference layout.css.prefixes.webkit, defaulting to false. Since Gecko 49.0 (Firefox 49.0 / Thunderbird 49.0 / SeaMonkey 2.46) the preference defaults to true.
