perspective-origin

Die CSS-Eigenschaft perspective-origin CSS property determines the position at which the viewer is looking. It is used as the vanishing point by the perspective (en-US) property.

The perspective-origin and perspective (en-US) 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: unset;

Values

x-position

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

<length-percentage> (en-US) 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> (en-US) 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

Initialwert	`50% 50%`
Anwendbar auf	transformierbare Elemente
Vererbt	Nein
Prozentwerte	bezieht sich auf die Größe der äußeren Box
Berechneter Wert	for `length` the absolute value, otherwise a percentage
Animationstyp	simple list of length, percentage, or calc

Formal syntax

<position>wobei 
<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> ] ]
wobei 
<length-percentage> = <length> | <percentage>
