Custom Elements
Custom Elements is a web standard that allows developers to define their own HTML elements with custom behavior and styling, extending the native HTML vocabulary. It is part of the Web Components suite, enabling the creation of reusable, encapsulated components that work across modern browsers. This technology provides a way to build complex user interfaces using custom tags that behave like standard HTML elements.
Developers should learn Custom Elements when building modular, reusable web components for large-scale applications or design systems, as it promotes code reusability and maintainability. It is particularly useful for creating UI libraries, embedding third-party widgets, or implementing complex interactive elements where standard HTML is insufficient. By using Custom Elements, developers can achieve better encapsulation and interoperability in web projects.
