Fallback for the interactive details element, emulating Chrome's behaviour in older browsers
npm install dom-details-fallbackrequire('dom-details-fallback')(null, true)To create the open/close marker the ::before pseudo element is used. This is normally styled with a vendor specific pseudo element, eg. ::-webkit-details-marker, so consider this if you want to change this:
summary::before, summary:before {
/* Custom closed marker */
}
details[open="open"] summary::before,
details[open="open"] summary:before {
/* Custom open marker */
}Will only polyfill if the open property is not present on a newly created <details> element.
Type: Element|Document
Default: window.document
Parent of the <details> elements that should be polyfilled.

Inject default CSS into <head>.
