How do Web Components work?
4 Key Web Technologies HTML Imports Shadow DOM HTML Templates
Custom Elements
Custom Elements • An API for creating your own HTML
elements by creating a Class that extends from HTMLElement • customElements.define()
HTML Templates • A mechanism for defining content that can
be stored for subsequent use in a document • <template></template>
Shadow DOM • A mechanism for encapsulating a DOM and
CSS, so that they can remain separate from the main document • document.body.attachShadow()
HTML Imports • A way to package and share HTML
files • <link rel=“import” href=“component.html”>
