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: revert-layer;
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.
