Suggestion for a landing page that matches data.altinn.no and follows Digdir's visual profile and Designsystemet. Stacked on #48 (logo/profile work); the diff shrinks to the landing-page commit once #48 is merged.

What it looks like

  • Navy band in the portal's colour (#022F51) with the all-white data.altinn.no lockup (profile rule for dark surfaces), a lead, primary/secondary buttons and the site search.
  • Three Designsystemet cards, "Kom i gang", "Tilgang og samtykke", "Tjenester og datasett", with links defined in data/landing.yaml and resolved through .Site.GetPage, so titles follow front matter.
  • Tinted "Hva er data.altinn.no?" section and a contact row (GitHub, Slack, e-mail).
  • Design element at the band's edge: the emblem's circle-and-square shape in the profile's graphic colours, placed right and low as the profile prescribes.

Structure

  • layouts/index.html is a standalone skeleton (no sidebar). The theme's <head> moved to a shared head.html partial; custom-head.html now gets the page context and loads designsystemet.css + landing.css on the home page only.
  • Designsystemet is vendored (@digdir/designsystemet-theme@1.11.0 brand/digdir + the used parts of @digdir/designsystemet-css@1.22.0). --ds-size-base is rescaled because the legacy stylesheet sets html to 10px.
  • The previous home-page text moved to a new "Om data.altinn.no" page (first in the sidebar). The home page keeps its aliases.

Walkthrough

The change adds a data-driven home page with revised overview content, grouped documentation links, shared page-head markup, and home-page styles. The page includes API and dataset links, optional search, documentation cards, about information, and contact links.

Changes

Site homepage and presentation

Layer / File(s) Summary
Landing-page content and link data
content/_index.md, content/om/_index.md, data/landing.yaml
The main overview is shortened, and a Norwegian overview is added. Landing-page groups define links for onboarding, access and consent, services, and datasets.
Landing-page rendering and styles
layouts/index.html, layouts/partials/custom-head.html, static/css/designsystemet.css, static/css/landing.css
The template renders the hero, optional search, documentation cards, about and contact sections. Styles define design-system tokens, components, layouts, and responsive behavior. Stylesheet links include a timestamp query parameter.
Shared templates, navigation, and search
themes/hugo-theme-altinn/layouts/partials/*, layouts/partials/topbar.html, layouts/partials/footer-content.html, static/css/custom.css, static/js/custom.js
The theme header delegates head markup to a shared partial, and the body uses a main element. Navigation and footer links gain accessibility attributes. Pagefind styling changes, and dialog positioning responds to trigger clicks and resets for Ctrl/Cmd+K.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Feature

Merge Risk: 🔵 Low · up to 9f9d1

Screen-reader users on documentation pages may be told that the homepage is current. This is a bounded accessibility issue; the change is otherwise mergeable with a small follow-up to condition the attribute.

Architecture Summary

Architecture risk: 🔵 Low · up to 9f9d1

The change affects 5 systems.

Review details

Systems and components

  • observed — layouts (service) was modified; 4 changed files map to changed impact.
  • observed — static (service) was modified; 4 changed files map to changed impact.
  • observed — themes (service) was modified; 4 changed files map to changed impact.
  • observed — content (service) was modified; 2 changed files map to changed impact.

Before / after behavior

  • observed — Modified behavior in content/_index.md: The page removes the table-of-contents setting and the detailed sections on services, datasets, data protection, and consent, replacing them with a concise overview. The new text describes direct source retrieval through a generic API, service-based access governed by legal authority, Altinn consent, or both, and identifies eBevis and Tilda as users. It retains the technical-documentation scope and links to the Collaboration Portal for non-technical information.
  • observed — Modified behavior in content/om/_index.md: Adds an overview of data.altinn.no, explaining how services govern dataset retrieval and authorization, how requests identify the requester, subject, and requested datasets, and how consumers can document a legal basis through consent, tokens, verifiable attachments, identity verification, or combinations of these. It also describes data-processing agreements for restricted data and the Altinn consent flow for legal-entity data, including representative approval and inbox notification.
  • observed — Modified behavior in data/landing.yaml: Adds three landing-page groups with Norwegian titles, icons, descriptions, and links covering API onboarding and testing, access and consent, and services and datasets. Links use page paths; several specify title overrides, while the others rely on page titles as noted in the comments.
  • observed — Modified behavior in static/css/designsystemet.css: The file’s CSS implementation was added. It introduces Designsystemet size, typography, color-scheme, semantic, and color-mapping tokens, plus styles for the listed base and component classes. Light and dark palette values apply to explicit schemes and are also assigned to data-color-scheme="auto" under the corresponding prefers-color-scheme media query.

A dedicated front page instead of the sidebar layout: a navy band in the
portal's colour (#022F51) with the all-white data.altinn.no lockup, a short
lead, "Kom i gang med API" and "Se datasettene" buttons and the site
search; three Designsystemet cards (Kom i gang, Tilgang og samtykke,
Tjenester og datasett) whose links come from data/landing.yaml and resolve
through .Site.GetPage; a tinted "Hva er data.altinn.no?" section; and a
contact row (GitHub, Slack, e-mail). The design element at the band's edge
is the emblem's circle-and-square shape in the profile's graphic colours.

Designsystemet is vendored (theme digdir 1.11.0, css 1.22.0, the parts used)
and loaded only on the home page; --ds-size-base is rescaled because the
legacy stylesheet sets html to 10px. The former home-page text moved to a
new "Om data.altinn.no" page (first in the sidebar); the home page keeps
its aliases. The theme's <head> is now a shared head.html partial, and
custom-head.html receives the page context so it can branch on .IsHome.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The band art now pairs the market icon (white, as the profile requires on
dark surfaces) with the design element tiles. The hero text keeps clear
of the art above 900px; below that the icon is hidden and only the faint
tiles remain behind the text.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The space reserved for the band art was a percentage of the viewport, so
on a wide monitor it squeezed the text into a narrow column. Text and art
now share the 1240px container: the text column is 56 % of it and the art
sits in the remaining 40 %, so the composition is the same at 1000px and
at 4K.

…over

The landing page has no sidebar, so the "Hopp til meny" jump link had no
target there; it is now only rendered on doc pages. The legacy
.nav-link-active:hover rule (white box, black text) is overridden on the
dark band so the active Docs item keeps white text on translucent navy.

The art was anchored to the container's outer edge, 51px past the cards
below it; its right edge now sits on the content edge, mirroring the text
on the left.

…ton row

"Steg for steg" joins "Kom i gang med API" and "Se datasettene", mirroring
the portal's three-button row. Buttons and search bar now share one
column so the search bar ends exactly where the buttons end. On laptop
widths (901 to 1150px) the text column gets 64 % and the art 34 % so the
row stays on one line and the icon clears it.

The landing page's body text is 18px (Designsystemet), so its nav items
were 25px wider than on the doc pages and the Docs item dropped to a
second row just above the compact-logo breakpoint once a scrollbar took
its 17px. The nav font is now fixed at 16px on every page, and the
compact emblem kicks in at 700px instead of 680px for margin.

- Focus on the band: Designsystemet's ring (white inside, blåsvart outside)
  vanished against navy and white borders, and a legacy a:focus rule turned
  the text black on navy (1.6:1). The band now uses a navy inner ring with a
  white outer ring, and focused buttons and links keep their colour. Nav
  links on the band get a 3px white outline instead of Chrome's dark default.
- The active Docs item carries aria-current="page".
- Card and "Les mer" links are at least 24px tall (WCAG 2.5.8).
- Footer icon links (X, Facebook, RSS) have accessible names.
- Doc pages: the content wrapper is a <main> landmark, and the three nav
  landmarks are labelled (Snarveier, Hovedmeny, Dokumentasjon) so they are
  distinguishable. axe-core reports no violations on the landing page,
  /api/, /datasett/ and /om/.

--pf-modal-top 8dvh to 16dvh so the dialog no longer jumps to the top

it still fits below that offset.

Every local stylesheet link carries ?v=<build time>, so a new deploy
forces browsers to refetch the CSS instead of showing the previous
version until a hard refresh.

Pagefind positions its dialog with --pf-modal-top; custom.js now sets
that from the clicked trigger's position (and the max height from the
room left below it), so the dialog reads as the search box expanding
rather than a panel at the top of the screen. Ctrl/Cmd+K keeps the
default offset from custom.css.

Text, excerpts, borders, hover highlight, matched-term colour, focus ring
and corner radius now use the same tokens as the landing-page cards
(neutral text, text subtle, border subtle, accent tinted, accent text,
8px radius), so the search reads as part of the site rather than a
third-party widget.

The logo box (38px) and the column headings (24px) were centred on each
other, so their tops sat 8px apart and each column's first text row
started at a different height. The logo's lettering is now level with
the headings, every column's first row starts 48px below the footer's
top edge, and the brand text and contact items use the same 24px line
rhythm as the link list.
