Measured entry

efferd-header-2

navbarminimal-flatmotion on file

A client-side React header shipped as a shadcn registry block. It combines a sticky, scroll-reactive shell with desktop navigation, sign-in and primary actions, plus a portal-rendered mobile menu. It depends on the shadcn Button API, Tailwind theme classes, a cn helper, a scroll hook, and bundled logo and menu icon components.

BARE BUILD

Verdict

A solid responsive shell with clean breakpoint behavior and useful scroll polish, but it is not drop-in outside its native stack. It needs a shadcn-style setup, and the unnamed logo link should be fixed before release.

Use it if

  • You need a compact marketing-site header with separate desktop and mobile navigation.
  • Your app already uses shadcn conventions, Tailwind theme tokens, and path aliases.
  • You want the header treatment to change after the page begins scrolling.

Skip it if

  • You need an accessibility-ready component without first labeling the logo link and menu control.
  • Your project does not use Tailwind or shadcn-style component primitives and you want a drop-in header.
  • You need framework router links, nested navigation, or account menus without adapting the source.

Providerno provider required in the harness

In a non-shadcn project, add Tailwind with compatible theme tokens and animation utilities, provide the Button and buttonVariants APIs, install radix-ui, configure the at-sign path alias, and supply a cn utility. Keep or replace the included logo, menu icon, and scroll hook, then add accessible names to the logo link and menu button.
