/* Without a script there is nothing to toggle, so the CSS the design kit ships takes over: no burger, the bar as a static list, and the panels on hover and :focus-within. `:focus-within` is what makes it keyboard operable - the trigger itself is inside the group, so tabbing to it opens the panel and the links behind it become reachable. Written out rather than expressed in utilities: this block is left untouched by Astro (`is:inline`), so it is plain CSS. 1024px is `--breakpoint-lg`, which a media query cannot read from a variable. **`@layer base` and `!important` together are load-bearing, and neither works without the other.** The bar and the panels carry the `hidden` attribute in the markup, so that a drawer does not flash open on a phone in the moment between parse and hydration. Tailwind's preflight implements that attribute as `[hidden]:where(:not([hidden="until-found"])) { display: none !important }` - an important declaration, and one that sits inside `@layer base`. For *important* declarations the cascade reverses the layer order: an important declaration in a layer beats an important declaration in no layer at all, whatever its specificity. So an unlayered `display: flex !important` here loses to preflight, and losing it means a JavaScript-less visitor gets a header with no navigation in it at all. Declaring these rules into `base` puts them in the same layer as preflight, where specificity decides again and `[data-mega-menu] [data-menu-bar]` (0,2,0) beats `[hidden]` (0,1,0). These rules are inside `<noscript>`, so they only ever apply where there is no script to remove the attribute. */ @layer base { [data-mega-menu] [data-menu-toggle], [data-mega-menu] [data-menu-close] { display: none; } [data-mega-menu] [data-menu-bar] { display: flex !important; } [data-mega-menu] [data-menu-group]:hover [data-menu-panel], [data-mega-menu] [data-menu-group]:focus-within [data-menu-panel] { display: block !important; } @media (max-width: 1023.98px) { [data-mega-menu] [data-menu-bar] { display: block !important; position: static; overflow: visible; padding: 0; background: transparent; } } }

Unser neuer phænovum Film

Habt ihr euch schon immer gefragt, was wir im phænovum machen?

Standbild aus dem Imagefilm: das Team winkt vor dem Eingang, darunter der Schriftzug phænovum Schülerforschungszentrum Lörrach-Dreiländereck

Habt ihr euch schon immer gefragt, was wir im phænovum machen?

Hier entdecken Schüler:innen die Welt der Naturwissenschaften und Technik. Mit kreativen Kursen und Projekten können sie eigene Theorien entwickeln, Experimente durchführen und ihrer Neugier freien Lauf lassen. Ob Physik, Biologie, Chemie oder Robotik – hier finden junge Forscher:innen spannende Herausforderungen!

Schaut euch hier unseren neuen Imagefilm an und lasst euch inspirieren!
