    JS module polyfill for HTML dialog element.

    Polyfill is in single javascript module file dialogicPolyfill.mjs. Include it into your site like this:

        <script type="module" src="/dialogicPolyfill.mjs" crossorigin="anonymous" integrity="sha256-dHKuaxOuwurk+H26C/fMr3WGod+O7AgrhBQ6b80qc/w="></script> 

    All other files like example-usage.html and example.css are there to help, but they are not needed for polyfill function.

    About dialog element

    It's simple, status of dialog element is stored in open attribute, when this attribute is presented on element dialog is visually show. When not, dialog element is hidden. You can change status by native javascript functions show() and close() on HTMLDialogElement. Look into example file.

    More detail info

    This polyfill is in js module, and modules are in default defer (even if you didn't add attribute defer), it means loaded asynchronously and executed after the document has been parsed.

    You can change this default behaviour by adding attribute async, but yout can't make it synchronous.

    All browsers have dialog element styled, even if they didn't support function like show() and close(). (This is for example Firefox now).
