The creation of custom HTML elements involves two main steps,
Define your custom HTML element: First you need to define some custom class by extending HTMLElement class. After that define your component properties (styles,text etc) using connectedCallback method. Note: The browser exposes a function called customElements.define inorder to reuse the element.
class CustomElement extends HTMLElement {
connectedCallback() {
this.innerHTML = “This is a custom element”;
}
}
customElements.define(“custom-element”, CustomElement);
Use custom element just like other HTML element: Declare your custom element as a HTML tag.
