Declarative user interfaces in plain HTML

Demos

The demos are a vital part of the Fore documentation. They range from simple to advanced examples and are a premier resource for learning Fore by example. If you are looking for the element reference or like to learn more about the inner workings please refer to the documentation.

Featured Demo

This is an example using the new 'Lens' component to inspect all data used in a page. You can inject this component dynamically by appending parameter 'lens' to the URL.
A Fore page with Lens

The demos with a green dot are new or have been enhanced since last release.
