Check the Browser compatibility table carefully before using this in production.

The CSSKeywordValue interface of the CSS Typed Object Model API creates an object to represent CSS keywords and other identifiers. The interface instance name is a stringifier meaning that when used anywhere a string is expected it will return the value of CSSKeyword.value.

Constructor

CSSKeywordValue.CSSKeywordValue()

Creates a new CSSKeywordValue object.

Properties

CSSKeywordValue.value

Returns or sets the value of the CSSKeywordValue.

Methods

Inherits methods from CSSStyleValue.

Examples

The following example resets the CSS display property to its defaults, setting the inline style attribute to style="display: initial" if viewed in the developer tools inspector.

#myElement {
  display: flex;
}

<div id="myElement">Check the developer tools to see the log in the console and to inspect the style attribute on this div.</div>

let myElement = document.getElementById('myElement').attributeStyleMap;
    myElement.set('display', new CSSKeywordValue('initial'));

console.log( myElement.get('display').value);  // 'initial'
