This example demonstrates a bookmark navigation system for a web page, allowing users to jump directly to specific sections such as name, address, phone number, and references. It uses HTML anchor elements with `href` attributes pointing to named targets (`#user`, `#addr`, `#tel`) and corresponding `id` or `name` attributes on target elements, along with `[TOP]` links to return to the page header. The page is built with plain HTML and CSS, relying on standard browser anchor navigation rather than JavaScript or React, despite the framework metadata.
