Adds a header prop to ::landing-tabs, which says where the headline, title and description go:

header Layout
side (default) Unchanged: the header sits above the tab list in its column, and the shorter column is bottom-aligned.
center The header is centered above both columns, and the tab list and panel are top-aligned below it.
left Same as center, with the header left-aligned.

side leaves a tall empty area beside the header whenever the panel is shorter than the header and tab list together. This happens on comark-content's "Bring your own source" section, and on devfra.me's "The same handler" and "Package it the way your tool ships". center and left avoid it. Because the default stays side, comark.dev and devfra.me don't change until a section opts in.

Implementation:

  • The header, tab list and panel are now items of one grid, so the header markup isn't duplicated between layouts. On side, the panel spans both rows of the other column; a 1fr auto row template keeps the old bottom alignment.
  • Inside a panel, the first block's top margin and the last block's bottom margin are removed, so a code card lines up with the tabs.
  • The panel wrapper uses min-w-0 instead of rounded-2xl overflow-hidden. Without the margins, the old wrapper clipped the code card's rounded corners; min-w-0 still keeps long code lines from widening the grid column.

Checked by rendering every landing-tabs section from comark.dev, devfra.me and content.comark.dev in all three variants, using this branch's playground at 1440 px and 390 px. comark.dev's two live demo components were replaced with code blocks of similar height. side matches the live sites, and no variant overflows on mobile. Unit tests (210), typecheck and lint pass; the 4 lint warnings were already on main.

Needed by comarkdown/comark-content#130 for its 4-tab sources section.

The header used to share a column with the tab list, which left a tall empty area above the code panel on desktop. It now sits centered above both columns, which are top-aligned.

🪧 More tips
  • Run npx skills add coldteadotai/pr-lens, then tell your coding agent: "Diagram the change you just made with PR Lens and attach it to the pull request."
  • Run npx @coldtea/pr-lens-cli analyze --base origin/main on a branch, then npx @coldtea/pr-lens-cli render .pr-lens/graph.json. Same lenses, your own model key, before the pull request exists
  • Click the link under each diagram to open it on a canvas you can zoom, pan and step through
  • The diagrams are links. Click one to open it on the canvas, then press W or click play to walk through the change
  • The CLI's render reads .github/pr-lens.yml and applies your renames, exclusions and lane pins at draw time
  • Set github.comment.collapsed: true in .github/pr-lens.yml to fold the comment behind one View architecture and data flow row. Drawing still runs as before
  • Set github.draw: on-demand in .github/pr-lens.yml and PR Lens stops drawing pull requests on its own. Comment @pr-lens draw on a pull request when you want that one drawn
  • Add .github/workflows/pr-lens.yml with coldteadotai/pr-lens/packages/action@v0 and your model provider's key as its api-key to run PR Lens from your own CI. Any /chat/completions endpoint works

📝 Walkthrough

The landing tabs component now renders its optional headline, title, and description above a two-column layout. The tablist occupies the first column, and the panels occupy the second. Panel content edge margins are reset, and the documentation reflects the layout.

The header now appears above the two-column tab layout. The vertical tablist remains in the first column, and panels occupy the second. Panel content resets the first child’s top margin and the last child’s bottom margin. The documentation describes the header above the tab columns.

Title check Warning The title is misleading because the pull request does not add a header prop. It moves and centers the existing landing-tabs header above the two-column layout.

Medium · Correctness

grid div has no top margin under the new header

The header div and the grid div are now siblings under UPageSection with no spacing between them, while the old layout boxed both in space-y-10. On the landing page the description text sits flush against the tab list.

Fix: Add a top margin to the grid wrapper, as the sibling does: <div class="grid lg:grid-cols-2 gap-8 lg:gap-12 items-start mt-12"> in LandingTabs.vue, matching LandingFeatures.vue’s <UPageGrid class="mt-12">.

1. [medium, correctness] app/components/landing/LandingTabs.vue line 87
   Problem: `grid` div has no top margin under the new header. The header div and the grid div are now siblings under `UPageSection` with no spacing between them, while the old layout boxed both in `space-y-10`. On the landing page the description text sits flush against the tab list.
   Fix: Add a top margin to the grid wrapper, as the sibling does: `<div class="grid lg:grid-cols-2 gap-8 lg:gap-12 items-start mt-12">` in LandingTabs.vue, matching `LandingFeatures.vue`'s `<UPageGrid class="mt-12">`.

`side` keeps the current layout and stays the default, so existing sites don't change. `center` and `left` put the header above both columns and top-align the tab list and panel.
