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

/* One-value syntax */ perspective-origin: x-position;  /* Two-value syntax */ perspective-origin: x-position y-position;  /* 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: revert; perspective-origin: unset; 

perspective-origin

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

The perspective-origin and perspective properties are attached to the parent of a child transformed in 3-dimensional space, unlike the perspective() transform function which is placed on the element being transformed.

Syntax

/* One-value syntax */ perspective-origin: x-position;  /* Two-value syntax */ perspective-origin: x-position y-position;  /* 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: revert; 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 definition

Initial value	50% 50%
Applies to	transformable elements
Inherited	no
Percentages	refer to the size of bounding box
Computed value	for <length> the absolute value, otherwise a percentage
Animation type	simple list of length, percentage, or calc

Formal syntax

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