Reusable custom HTML elements are created using Web Components standards, defining new tags with custom behavior and lifecycle callbacks to build framework-agnostic design systems.

How does Shadow DOM isolate styles when building web components?▼

Shadow DOM encapsulates styles and markup for web components, ensuring true component isolation by preventing external styles from bleeding into the custom elements.

What is the best way to allow content projection in custom HTML elements?▼

The best way to allow content projection in custom HTML elements is by using templates and slots, which efficiently render component structure and accept external child content.

Can I use web components in any frontend javascript project regardless of the framework?▼

Yes, web components can be used in any frontend javascript project regardless of the framework, because they generate framework-agnostic custom HTML elements.

When do I need lifecycle callbacks in custom elements?▼

Lifecycle callbacks are needed in custom elements when you want to define custom behavior triggered by DOM events, such as logging a message when the element is connected to the DOM.
