Skip Link

Free · MIT

Headless, accessible, and styled entirely through the attribute surface below — bring your own CSS system, or start from the reference theme.

Install

Without a flag you get no styling at all — plain HTML carrying the attribute surface below. --theme copies the same theme in two dialects;--bridge lumos re-points either one onto Lumos for Astro's tokens (it needs a theme to re-point, and Lumos itself, already in your project).

Unstyled — behavior only, you write the CSS

Install command
npx astrocraft-ui add navigation/skip-link

Plain-CSS theme — no build step

Install command
npx astrocraft-ui add navigation/skip-link --theme css

Tailwind theme — needs Tailwind v4

Install command
npx astrocraft-ui add navigation/skip-link --theme tailwind

Plain-CSS theme, re-pointed onto Lumos tokens

Install command
npx astrocraft-ui add navigation/skip-link --theme css --bridge lumos

Tailwind theme, re-pointed onto Lumos tokens

Install command
npx astrocraft-ui add navigation/skip-link --theme tailwind --bridge lumos

BackToTop & SkipLink

Both are focus moves that happen to scroll, which is the half everyone drops. The button below appears once you are 400px down and sends the caret — not just the viewport — back to <main>. SkipLink is not in this box at all: it is the first element in the page's <body>, which is the only place a bypass block means anything. Reload and press Tab.

Attribute surface

With no class-merging machinery, these attributes are the whole extension point. State is a data-attribute or a native attribute; visibility is the hiddenattribute. Generated from source by pnpm slots.

Source

What the command copies — 2 files, alias-free so the copy lands standing alone. This is the whole component; there is nothing else.

src/components/ui/navigation/skip-link/SkipLink.astro
---
// src/components/ui/navigation/skip-link/SkipLink.astro — headless primitive (see ../../README.md).
// The WCAG 2.4.1 bypass block: the first focusable thing on the page, hidden until it has focus.
// Four lines, required by every conformance level, and missing from almost every project — which is
// the entire reason it is a file here rather than a note in the docs.
//
// Render it as the FIRST element inside <body>, before any header, and point `href` at your main
// landmark's id. Two details that are easy to get wrong and are handled here:
//
//   • It is hidden with `clip-path`, never `display: none` or `visibility: hidden` — either of those
//     also removes it from the focus order, which is the one thing it needs to be in. structure.css
//     carries that rule, scoped to `:not(:focus)`.
//   • `:focus`, not `:focus-visible`. A skip link is reached by Tab and by nothing else, and
//     `:focus-visible` heuristics are not something to bet a legal requirement on.
//
// Give the target `tabindex="-1"` if it is not natively focusable: browsers move the sequential
// focus start to a fragment target either way, but the explicit attribute is what makes the CARET
// land there in every engine, and it costs one attribute.

The component source, copied into your project by npx astrocraft-ui add navigation/skip-link — no package dependency, no CSS to fight. Whatever the paid blocks compose, this is it.
