Specific Setting - Scroll-ID (Anchor)
You can give every panel an own Scroll-ID (HTML ID).
You can give for example your Panel - About the ID about. So whenever a user types at the end of the URL #about he will land directly on your Panel - About.
You can do the same logic for every link or button on your page and also with the Navigation.
<!-- this is an example for a link --> <!-- which points to a section with the scroll-id: "portfolio" --> <a href="index.html#portfolio">Portfolio</a> <!-- and this would be your panel with the scroll-id: "portfolio" --> <section id="portfolio"> ... </section>
