Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The CSSPositionValue interface of the CSS Typed Object Model API represents values for properties that take a position, for example object-position.


CSSPositionValue() Non-standard Deprecated

Creates a new CSSPositionValue object.

Instance properties

CSSPositionValue.x Non-standard Deprecated

Returns the item's position along the web page's horizontal axis.

CSSPositionValue.y Non-standard Deprecated

Returns the item's position along the vertical axis.

Instance methods



The following example positions a container <div> 5 pixels from the top and 10 pixels from the left of the page.

const replacedEl = document.getElementById("image");
const position = new CSSPositionValue(CSS.px(35), CSS.px(40));

replacedEl.attributeStyleMap.set("object-position", position);
console.log(position.x.value, position.y.value);

We set the object-position property, then check the values returned.
