media-inline

It allows to homologate the behavior of image-set or img[srcset].

media(string expression, function callback)

Transform the string expression to an event subscribe to @media.

Example: value1 200w value2 300w value3 200w!

1. The callback will receive, for example, value1 when the browser displays the condition min-width: 200w.
2. The callback will receive, for example, value1 when the browser displays the condition min-width:300w.
3. The callback will receive, for example, value1 when the browser displays the condition max-width:300w.

imageSet(HTMLElement element, string expression)

Given the 2 arguments, subscribe to the element to the given @media, changing the property element.style.<background|backgroundImage>, depending on the expression.

import {imageSet} from "media-inline";

let $el = document.querySelector("img");

imageSet($el,`image_1.jpg 1400w image_2.jpg 1400w!`)

The previous example will change to the image_1.jpg only when min-width: 1400px is met, otherwise it will be changed to img_2.jpg only when max-width: 1400px is met.

srcSet(HTMLElement element, string expression)

Given the 2 arguments, subscribe to the element to the given @media, changing the property element.src, depending on the expression.

import {srcSet} from "media-inline";

let $el = document.querySelector("img");

srcSet($el,`image_1.jpg 1400w image_2.jpg 1400w!`)

The previous example will change to the image_1.jpg only when min-width: 1400px is met, otherwise it will be changed to img_2.jpg only when max-width: 1400px is met.
