The UI5 Web Components are the new offering of UI5 to provide a set of reusable UI elements to you which can be used for your static web sites or for web application using any web framework of your choice with a minimalistic footprint. They allow you to create a consistent user experience aligned to the SAP Fiori Design Guidelines and incorporate the Fiori 3 design. Web Components are a set of features which allow to enhance the HTML vocabulary with custom HTML elements when the standard HTML elements are not sufficient (for example, a Button with an icon or a DatePicker). The custom HTML elements allow to share those features and qualities in a standard way. The complexity of HTML, CSS and components behavior is encapsulated behind a custom HTML element. The interaction with the custom HTML elements is done using the standard DOM API.
