Web components are a set of web platform APIs and a specification for creating reusable and encapsulated custom HTML elements. They allow web developers to build their own HTML elements with their own encapsulated styling and behavior. Web components consist of several key technologies and concepts:
<my-element>), making them distinct from built-in HTML elements.
Shadow DOM (Document Object Model): Shadow DOM is a way to encapsulate the internal structure and styling of a web component so that it doesn't interfere with or get affected by the styles and structure of the rest of the web page. It provides scoped CSS and DOM isolation for components.
Web components offer several advantages:
Reusability: Web components are highly reusable. Once defined, they can be used in multiple parts of a web application or across different projects.
Modularity: Web components promote modular development, making it easier to manage and maintain code.
Consistency: Custom elements ensure that developers use the same HTML tags and structure consistently throughout an application or website.
