How this works

The mega panel uses `position: fixed; left: 0; width: 100%` so it spans the full viewport. Inside, CSS Grid creates the multi-column layout. The panel transitions in with `opacity` + `transform: translateY` on the parent `:hover`/`:focus-within` selector.

Make it yours

  • Change the grid column count in `.nav-03__mega-grid` (currently `repeat(4, 1fr)`) to adjust the column layout. Featured cards use a separate `.nav-03__featured` class with a gradient background — swap the gradient stops to match brand colors.

Gotchas — read before shipping

  • Full-width fixed mega menus require the `<nav>` to be positioned relative to the viewport, not a scroll container. Nesting inside `overflow: hidden` parents will clip the panel.
