Glassmorphism Navbar Block for React

Yes. The band is an aria-hidden layer behind the panel (the mesh and the dots inside the -z-10 wrapper): swap it for an image, a video or a gradient and keep the panel. The panel needs something with detail behind it to look like glass, so a flat page colour shows no blur. The wrapper's mask fades the band out toward its foot, so the bar's bottom edge, which is the next block's top rule, isn't cut by a hard edge.

The panel is 70% page colour, blurred, and the mesh is held to a quarter of its strength in foreground tones with no hue, so the links keep their contrast in light and dark and in every preset. If you put a busier image behind it, raise the panel to bg-background/80 or lower the image's strength rather than darkening the links.

The links sit in a nav named Main after the wordmark (a link home), the current page is aria-current="page", and Tab walks the wordmark, the links, Sign in, Try it free and the menu button. The band is hidden from assistive technology and takes no pointer or focus. Try it free renders the link it's given with render, with nativeButton={false}.

Below the md breakpoint the wordmark, Try it free and a menu button stay in the panel. The button opens a drawer from the bottom with a grabber, the four links (the current page tinted and dotted), then Sign in and Try it free. Focus moves into the drawer and stays there; Escape, a swipe down, a tap outside it or choosing a link closes it, and focus goes back to the menu button.

The mesh drifts and a diagonal wave crosses the dots, both so slowly you barely see them move, and a band of light sweeps across Try it free once on hover and keyboard focus. With reduced motion the mesh and the dots rest where they start, the drawer appears without sliding and the light fades in where it stands. The dots don't react to the pointer.
