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.

Try it

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.
  • bottom, a keyword being a shortcut for the 100% percentage value.

Formal syntax

perspective-origin = 
<position>

<position> =
[ left | center | right | top | bottom | start | end | <length-percentage> ] |
[ left | center | right | x-start | x-end | <length-percentage> ] [ top | center | bottom | y-start | y-end | <length-percentage> ] |
[ center | [ left | right | x-start | x-end ] <length-percentage>? ] && [ center | [ top | bottom | y-start | y-end ] <length-percentage>? ] |
[ center | [ start | end ] <length-percentage>? ] [ center | [ start | end ] <length-percentage>? ]

<length-percentage> =
<length> |
<percentage>
