Web/API/CSSPositionValue

ObsoleteThis feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

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

Constructor

CSSPositionValue.CSSPositionValue(): Creates a new CSSPositionValue object.

Properties

CSSPositionValue.x: Returns the item's position along the web page's horizontal axis.
CSSPositionValue.y: Returns the item's position along the vertical axis.

Methods

None.

Examples

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

let replacedEl = document.getElementById( 'image' );
let 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.</p>
<img id="image" src="https://mdn.mozillademos.org/files/12668/MDN.svg" alt="MDN Logo"/>
