//! Example: Web Components & Custom Elements
//! -----------------------------------------
//!
//! Web components are a flavor of html elements that can be user-defined.
//! See: https://www.webcomponents.org for more information.
//!
//! Users who use webcomponents typically don't use Dioxus. However, if you would like to use webcomponents in Dioxus,
//! you can easily create a new custom element with compile-time correct wrappers around the webcomponent.
//!
//! We don't support building new webcomponents with Dioxus, however.  :(
