`CSS encapsulation`


The elements HTML structure is initialized in a Shadow DOM, so it is impossible to apply CSS to it. If you need to change the element's default style for any reason, you should open up a new issue (or a pull request!), describing your use case, and we'll work with you on solving the problem.
Browser support

Browsers without native [custom element support][support] require a [polyfill][]. Legacy browsers require various other polyfills. See [examples/index.html`][example] for details.
