Semantic HTML Patterns

Custom Web Components

Create reusable components with shadow DOM and encapsulated styles.

class MyComponent extends HTMLElement {
  constructor() {
    super();
    this.attachShadow({ mode: 'open' });
  }
}
customElements.define('my-comp', MyComponent);

Accessible Templates

Design components with ARIA attributes and semantic roles.

<div role="alert" aria-live="polite">
  Live region content</div>
