CSSStyleRule: styleMap property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The styleMap read-only property of the
CSSStyleRule interface returns a StylePropertyMap object
which provides access to the rule's property-value pairs.
Value
A StylePropertyMap object.
Example
The following example shows styleMap being used to modify a style using
the StylePropertyMap.set() method.
js
const stylesheet = document.styleSheets[0];
Object.values(stylesheet.cssRules).forEach((block) => {
if (block.selectorText === "button") {
block.styleMap.set("--main-color", "black");
}
});
