| description | IOP Design System (IDS) design tokens, theming, breakpoints, typography and motion for the docouture Antora UI bundle. USE WHEN writing or editing any CSS in code/packages/ui-bundle, adding a colour/spacing/font value, implementing dark mode or responsive behaviour, or wiring PostCSS. EXAMPLES: 'what colour should this border be', 'add dark mode', 'make this responsive', 'why is my custom property missing in the build', 'set the heading font size'. |
IOP DS — Foundations
The design system is shipped as npm packages, not as a Figma spec you transcribe.
Everything below already exists as plain CSS. Read it, import it, reference it. Never
re-author it.
These packages are not a dependency of this workspace. code/packages/ui-bundle
ships a small, generated derivative (src/css/ids-tokens.css, src/css/ids-breakpoints.css)
and nothing else — no node_modules/@inditex/* at the workspace root, no Artifactory
credential needed for a normal pnpm install. To read the real DS source described in
this skill, run just ids-install first: it installs the two packages into
code/tools/ids/node_modules/, a sidecar outside the pnpm workspace, kept there for
exactly this — reference while building or extending a component. See
code/tools/ids/README.md and the iop-ds-reference skill for the full story
(what's generated, how, and when to re-sync).
| package | version | role |
|---|
@inditex/sewingiopdsweb-styles | 1.28.0 | tokens, theming, breakpoints, motion, z-index, normalize, mixins, PostCSS plugin |
@inditex/sewingiopdsweb-react-components | 1.28.0 | per-component BEM CSS (framework-agnostic) — see the iop-ds-components skill |
Figma (aVzfmpuxRcJLsOLqZJaqAH Foundations, k7yFLKOvab4OBB1v6xhM6i Core Components)
is the specification. The npm packages are the implementation, and where the
two disagree the packages win — the Figma breakpoint page, for one, is stale.
Use Figma only to understand intent. See reference/figma.md.
The three laws
- Never write a literal. No hex, no px, no font stack, no duration, no z-index.
Every value comes from an
--ids-* custom property. If you cannot find a token
for what you need, you are styling something the DS does not model — say so
rather than inventing a value.
- Never write a width media query by hand. Use the
@custom-media names.
- Never flatten custom properties at build time. Theming, the density scale and
the resolution tiers are all runtime custom-property swaps.
postcss-custom-properties
must run with preserve: true (or not at all).
Token grammar
--ids-<domain>-<group>-<variant>[-<state>]
kebab-case throughout. Domains: color, size, typo, motion, z, comp
(--ids-comp-* are component-scoped tokens; prefer the generic one when both exist).
Quick map of what to reach for:
| you want | token family | example |
|---|
| text colour | --ids-color-content-* | --ids-color-content-low |
| surface colour | --ids-color-bg-* | --ids-color-bg-low |
| border colour | --ids-color-border-* | --ids-color-border-low |
| hover/pressed/disabled/focus | --ids-color-*-states-* | --ids-color-border-states-focus |
| accent hue | --ids-color-alt-<hue>-{high,mid,low} | --ids-color-alt-blue-high |
| chart series | --ids-color-viz-* | --ids-color-viz-item-1-level-02 |
| any spacing or dimension | --ids-size-N | --ids-size-100 (16px) |
| border width | --ids-size-border-{none,default,high} | resolution-aware |
| corner radius | --ids-size-radius-{none,rounded,full} | |
| text style | --ids-typo-<role>-<size>[-high] | --ids-typo-body-m |
| transition | --ids-motion-{micro,macro}-* | --ids-motion-micro-states |
| stacking | --ids-z-* | --ids-z-tooltip |

Theming — class-based, not attribute-based
The DS switches theme with a class on the root element:
<html class="ids-theme-light ids-scale-medium">
.ids-theme-light / .ids-theme-dark. Every DS component stylesheet is written
against those selectors, so a [data-theme] attribute would silently do nothing.
The DS also emits :host(.ids-theme-dark) variants for shadow DOM; irrelevant here
but do not delete them when copying CSS.
Persistence key is ids-theme in localStorage (IDS_THEME_STORAGE_KEY).
The DS does not ship a prefers-color-scheme fallback — that is ours to add,
and it must only apply when the user has made no explicit choice.
Never hardcode a dark value. --ids-color-bg-default is already #fff in light and
#000 in dark; a rule that references it needs no dark-mode counterpart at all.
Only write a .ids-theme-dark block when a value genuinely is not expressible as a
token — e.g. the --hljs-* syntax palette.
Density scale
.ids-scale-medium (default) and .ids-scale-large rescale every --ids-size-*
and --ids-typo-font-size-* / --ids-typo-line-height-*. ids-size-100 is 16px at
medium and 20px at large. docouture ships ids-scale-medium and does not expose a switcher.
.ids-pda-true / .ids-pda-false enlarges touch targets for handheld terminals.
docouture sets neither, which defaults to false.
Resolution tiers — pure CSS, no JavaScript
The DS retargets two things by device pixel ratio, entirely through media queries:
| fallback | mid (≈1×) | high (≥2×) |
|---|
--ids-size-border-default | 1px | 1px | 0.5px |
--ids-size-border-high | 2px | 2px | 1px |
--ids-typo-font-weight-default | 400 | 350 | 350 |
--ids-typo-font-weight-mid | 500 | 400 | 400 |
--ids-typo-font-weight-high | 600 | 500 | 500 |
Hairlines only on displays that can render them; heavier weights on low-res displays
so the Light 350 stays legible. Do not reimplement this, do not detect DPR in JS, and
do not use --ids-typo-font-weight-* for emphasis — they are density compensation,
not a weight scale. Force a tier with .ids-resolution-{standard,mid,high} if ever needed.
Breakpoints
Four tiers, mobile-first, consumed as @custom-media:
@media (--ids-breakpoints-m) { … }
@media (--ids-breakpoints-s-only) { … }
| tier | range | columns | margin | gutter |
|---|
| XS | <= 512px | 6 | 16px | 16px |
| S | >= 513px | 12 | 32px | 24px |
| M | >= 1024px | 12 | 56px | 48px |
| L | >= 1680px | 12 | 64px | 56px |
--ids-margin and --ids-gutter already track the tier — use them for page padding
and grid gaps instead of re-deriving the numbers. Full list of names in
reference/breakpoints.md.
The @custom-media names are resolved from code/packages/ui-bundle/src/css/ids-breakpoints.css
— a generated derivative of the DS's own variables/breakpoints.css, prepended to every
stylesheet by gulp.d/lib/ids-custom-media.js before postcss-custom-media runs. You never
import either file yourself; if a breakpoint you need is missing from the derivative, add
the (--ids-breakpoints-*) reference to your CSS and run just ids-install && just ids-sync
— the generator only emits breakpoints it finds actually referenced.
Typography
Composite font: shorthand tokens, each with a matching letter-spacing and
text-transform token. Always apply all three, or use the mixin:
.thing {
font: var(--ids-typo-body-m);
letter-spacing: var(--ids-typo-body-m-letter-spacing);
text-transform: var(--ids-typo-body-m-text-transform);
font-variant-numeric: var(--ids-typo-font-variant-numeric);
}
.thing { @mixin ids-body-m; }
Roles: display-{s,m,l}, title-{xs,s,m,l,xl}, body-{m,l}, label-{m,l},
detail-m, code-m. A -high suffix means the emphasised weight of the same style.
⚠ Every title-* style is text-transform: uppercase. That is correct for
application chrome and wrong for documentation prose. Article headings in docouture use
title-* sizing with the transform explicitly reset — that deviation is deliberate
and documented in reference/typography.md. Do not "fix" it back.
Fonts are loaded from a public CDN, not bundled:
https://amgassets.inditex.com/amigaweb/typography/zara-helvetica-now/zara-helvetica-now-sw10.css
https://amgassets.inditex.com/amigaweb/typography/noto-sans-mono/noto-sans-mono.css
Families resolve as Helvetica Now Text SW10 and NotoSansMono via
--ids-typo-font-family-{primary,monospace}. Hosts ending .cn must swap the CDN to
amgassets.inditex.cn. Never add @fontsource packages or @font-face blocks for these.
Motion
--ids-motion-duration-{s,m,l}[-high], four --ids-motion-easing-standard-{1..4},
and six ready-made composites you should use directly:
transition: var(--ids-motion-micro-states);
prefers-reduced-motion is already handled inside motion.css — it collapses every
duration to 0.01ms and every easing to linear. Do not add your own
prefers-reduced-motion block for anything driven by these tokens.
Where things live
Real DS source (needs just ids-install first — see the intro):
code/tools/ids/node_modules/@inditex/sewingiopdsweb-styles/
variables/index.css themes, scales, resolution tiers, margins/gutters
variables/breakpoints.css @custom-media source of truth (do not import directly)
typography.css composite font tokens
motion.css durations, easings, composites, reduced-motion
zindex.css --ids-z-*
mixins/index.css @define-mixin ids-*
normalize.css scrollbar.css
postcss/custom-media.cjs PostCSS plugin (reference only — the build uses its own
equivalent, gulp.d/lib/ids-custom-media.js, sourced from
the committed derivative; see iop-ds-reference skill)
The generated derivative the build actually consumes:
code/packages/ui-bundle/src/css/
ids-tokens.css the --ids-* declarations src/css/**/*.css references, generated
ids-breakpoints.css the @custom-media declarations src/css/**/*.css references, generated
ids.lock.json DS version + source hashes the above were generated from
To look a token up, grep the real package rather than guessing:
$ just ids-install
$ grep -o '\-\-ids-color-alt-[a-z-]*:#[0-9a-f]*' \
code/tools/ids/node_modules/@inditex/sewingiopdsweb-styles/variables/index.css
In this repo
code/packages/ui-bundle is a fork of antora-ui-default and still carries its own
variable vocabulary (--body-font-color, --panel-background, --nav-*, …). Those
are not dead — src/css/bridge.css re-points each of them at an --ids-* token,
so the 18 legacy stylesheets keep working and re-theme for free.
- Styling existing chrome → change
bridge.css, not the leaf stylesheet.
- Styling something new → use
--ids-* directly, no bridge entry.
- Never add a new
--body-* / --nav-* style variable. The bridge only shrinks.
