The CSSImageValue interface of the CSS Typed Object Model API represents values for properties that take an image, for example background-image, list-style-image, or border-image-source.

The CSSImageValue object represents an <image> that involves a URL, such as url() or <image()>, but not linear-gradient() or element().

Instance properties

None.

Instance methods

Inherits methods from CSSStyleValue.

Examples

We create an element

html

<button>Magic Wand</button>

We add some CSS, including a background image requesting a binary file:

css

button {
  display: inline-block;
  min-height: 100px;
  min-width: 100px;
  background: no-repeat 5% center url("magic-wand.png") aqua;
}

We get the element's style map. We then get() the background-image from the style map and stringify it:

// get the element
const button = document.querySelector("button");

// Retrieve all computed styles with computedStyleMap()
const allComputedStyles = button.computedStyleMap();

// Return the CSSImageValue Example
console.log(allComputedStyles.get("background-image"));
console.log(allComputedStyles.get("background-image").toString());
