For example, the menu has a `<ul>` element that contains multiple `<li>` (list items). Similarly, the status bar contains a series of `<span>` elements to display different status information.\n\nPlease note that innerText has been used to showcase where the configurable text would go, a strict HTML-only requirement would omit these attributes. Also, empty strings for `class` and `id` attributes in the menu items are placeholders for potential unique identifiers or classes.",
