CSSPositionValue

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

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.

Examples

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);
console.log(replacedEl.computedStyleMap().get("object-position"));

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

#image {
  width: 300px;
  height: 300px;
  border: 1px solid black;
  background-color: #dededf;
  object-fit: none;
}

<p>
  Check the developer tools to see the log in the console and to inspect the
  style attribute on the image.
