element-match-media

Like window.matchMedia() but for HTML elements.

About

Parse media queries from the context of an element.

Usage

``js
elementMatchMedia(element, mediaQueryString)
`

- element is a reference to a DOM node, or a string representing a CSS selector to match with document.querySelector()
- mediaQueryString is a string containing a media query

This function evaluates the mediaQueryString as though the viewport's dimensions matched those of the element given to the function. It returns the MediaQueryList object.

Most of the time you use this you'll probably be wanting to check the .matches property to see whether the media query evaluates to true or false.

};
}
