Markdown
Every syntax the renderer speaks, on one page - and the atomic CSS that styles it, visible in action.
This page is the renderer's own showcase. Everything below is plain Markdown in a file on GitHub - the button above opens it - and every visual decision comes from the atoms stylesheet. There is no page-specific CSS; what you see is the token scale, the type utilities and the blocks, doing what they do on every other page.
Prose
Text sets in the body face on the paper ground. Bold carries weight 600,
italics lean, and inline code sits on the code material. A mention of a
component this site owns - like CardCardTitle, optional meta, arbitrary body. Heading level is a prop so the outline stays correct.@sushindustries/ui · layout or PaginationPaginationPages as links with first and last always reachable. The window everyone already knows, and nothing that breaks middle-click.@sushindustries/ui · docs - becomes a reference:
hover one and its own description rises, served from the same registry entry
the install commands come from.
You can also cross something out and it dims as well as strikes, break a
line hard with a backslash
like that, and hang a claim on a footnote1 that collects itself at the
bottom of the page2.
A blockquote holds somebody else's words at one remove: inset, quieter, still readable.
And a quote inside a quote steps in once more.
Reference-style links work too: define the registry once, use it anywhere in the prose.
Lists
Unordered, ordered, nested - each level indents by one spacing token:
- The scale is short on purpose
- Values come from tokens, never from numbers
--s-1through--s-7for space--t-xsthrough--t-lgfor type
- What is not in the scale is not in the design
- Write the Markdown
- The catalogue picks it up
- The page exists
An ordered list may start anywhere:
- Seventh
- Eighth
And a task list carries its own checkboxes, accent-coloured by the theme:
- Parse the Markdown
- Style every element it can emit
- Run out of syntax
Structure
Headings run six levels deep. The first three carry the site's display scale; past that, depth becomes quieter rather than smaller and smaller:
A third level
A fourth level
A fifth level, set as a label
A thematic break rules a section off without starting a new one:
That line above is ---, rendered as the same soft rule the tables use.
Table
Tables get the line tokens, and the delimiter row's colons set per-column alignment - left, centre, right:
| Utility | Bootstrap says | Does |
|---|---|---|
.flex | d-flex | display: flex |
.gap-3 | gap-3 | gap: var(--s-3) |
.ms-auto | ms-auto | the flex push |
.text-end | text-end | text-align: end |
Code
A fence with a language gets the charcoal slab and the CLI palette. Name a file and it becomes the tab:
import { Badge } from "@sushindustries/ui";
export function Hello() {
return <Badge tone="docs">Rendered from Markdown</Badge>;
}A shell fence gets the terminal glyph instead:
pnpm add @sushindustries/ui @sushindustries/atomsCallouts
The four callouts
Note, tip, warning and caution - the same classes the parser emits, styled once in atoms, reused by the AlertAlertThe Markdown callout, reachable from JSX - application news in the same box the docs already use.@sushindustries/ui · content component so the two boxes are one.
[!TIP] Write pages as content
pnpm new page <slug> scaffolds a file like this one.
[!WARNING] Blocks must close
An unclosed ::start: block swallows the rest of the document.
[!CAUTION] No page-specific CSS The moment a page needs its own stylesheet, the system has failed it.
Blocks
Layout is content too. A grid of cards, written as comments:
Tokens
Colour, space and type as variables. Everything else reads them.
Utilities
One class, one job, token values only - the Bootstrap axes, house spelling.
Blocks
Earned names for compositions used in three places or more.
And a live component, running - not a screenshot:
tanstacktanstack add https://adamjurek.com/r/tanstack/card.jsonpnpm dlx shadcn@latest add https://adamjurek.com/r/shadcn/card.jsonA video is a block too, and it costs nothing until you press it. What sits on the page is a poster and a button; the frame, the third-party script and the cookies arrive with the click and leave again when you press stop:
Rick Astley, 1987. The most-linked video on the internet, here because everyone already knows what it should look like.
The same block, pointed at Mux, which is the one to reach for when the video is
mine. <mux-player> is a custom element rather than a frame, so it is not at
the mercy of another site's opinion about being embedded, it adapts its bitrate
to the connection, and its chunk is fetched by the click that needs it:
Hosted video, played by @mux/mux-player-react. The player is loaded on press and unloaded on stop, like every other provider here.
Even the 3D viewer is a block. The model below is the site's own mark, loading through TanStack Query in parallel with the viewer code, and only once you scroll near it:
Loading model
The entity net
Two more blocks exist for the half of a page that machines read. Each renders what you see and publishes one node into the page's schema.org graph, joined to the rest by identifier rather than by repetition:
Rated 5 out of 5
The review block is a quote you can see and a
Reviewa crawler can follow. ItsitemReviewedpoints at whatever the page is about, so it is attached to a thing rather than floating beside one.
self="true" on a person means me, so the node becomes the site's own
Person rather than a second one with the same name - the duplicate that
makes an entity graph useless. Everything else on the page refers to that same
identifier: the site publishes it, every page is authored by it, and the
component pages point their source-code nodes at the pages they are on.
What is deliberately off
The parser can do four more things this site chooses not to use, and an author should know they are choices rather than gaps:
| Syntax | Instead |
|---|---|
Raw HTML (allowHtml) | Blocks. The parser's bounded AST is the trust boundary that makes rendering author content safe, and it stays closed |
| Autolink literals | Write the explicit [text](url) link |
| Setext headings | # headings, which the hierarchy check can count |
| Indented code blocks | Fenced blocks, which can name a language and a file |
A machine, from a list
The deviceDeviceA phone, a tablet or a laptop in CSS 3D, chosen by the stylesheet rather than by JavaScript, whose screen is a real scroll container with real controls in it.@sushindustries/ui · layout block draws a machine and puts a desk on its screen. The desk is
its own Markdown file in content/desks/, and the extension on each line
decides what that line is:
<!-- ::start:device from="home" kind="tablet" title="SUSHINDUSTRIES" -->
<!-- ::end:device -->- assistant.app `terminal` - Ask about this site
- components.folder `layers`
- [Button](/components/button)
- [Card](/components/card)
- [Writing](/posts) `note`.app opens an app in a window, .folder holds whatever is indented under it,
and a plain link stays a link. Adding an icon to the machine on the front page
is adding a line to a list.
The point
Every element on this site has a Markdown mirror, every page is a file a pull request can touch, and this one exists so you can see the whole vocabulary at once. Copy it, keep the blocks you need, and delete the rest.
