Skill: Figma to IDS Translation

Purpose

Translate Figma design properties and structures into IDS (Iress Design System) component implementations. This skill helps AI agents interpret Figma design metadata (from tools like Figma MCP or exported design specs) and produce accurate IDS code.

Process

• Analyse Figma structure — Identify frames, auto-layout, and component instances

• Map components — Match Figma component names/variants to IDS components

• Extract tokens — Convert Figma design values to IDS design token references

• Generate code — Produce clean React/TypeScript with proper IDS imports

Important: IDS v6 is currently in alpha. Install with the @alpha tag:

npm install @iress-oss/ids-components@alpha

Figma → IDS Mapping

Read references/component-mapping.md for the full Figma component → IDS component mapping table.

Read references/token-mapping.md for Figma design values (colours, spacing, radius, typography) → IDS token mapping.

Translation Examples

Figma: Login Form Frame

Figma structure:

• Frame: Auto-layout vertical, gap 16px, padding 24px

• Text: "Log In" (Heading H2)

• Input: "Email" (Text Input)

• Input: "Password" (Password Input)

• Button: "Sign in" (Primary)

• Text: "Forgot password?" (Link)

IDS implementation:

import { IressStack, IressText, IressField, IressInput, IressButton, IressLink, IressCard, } from '@iress-oss/ids-components';

function LoginForm() { return ( <IressCard p="6"> <IressStack gap="4"> <IressText element="h2">Log In</IressText> <IressField label="Email" htmlFor="email" required> <IressInput id="email" type="email" /> </IressField> <IressField label="Password" htmlFor="password" required> <IressInput id="password" type="password" /> </IressField> <IressButton mode="primary" type="submit"> Sign in </IressButton> <IressLink href="/forgot-password">Forgot password?</IressLink> </IressStack> </IressCard> ); }

Figma: Alert Banner

Figma structure:

• Frame: Fill #EBF9F5 , border-radius 12px, padding 16px

• Auto-layout horizontal, gap 8px

• Icon: "check_circle"

• Text: "Your changes have been saved" (Body MD)

IDS implementation:

import { IressAlert } from '@iress-oss/ids-components';

// IressAlert already handles the layout, icon, and styling <IressAlert status="success">Your changes have been saved</IressAlert>;

Key insight: IDS components encapsulate their styling. Don't recreate layout/colours from Figma — use the component's props (like status ) and let IDS handle the visual treatment.

Figma: Status Modal (Danger Confirmation)

Figma structure:

• Modal frame with danger icon in header

• Heading: "Delete record?"

• Body text: "This action cannot be undone."

• Footer: Two buttons (Cancel, Delete)

IDS implementation:

import { IressModal } from '@iress-oss/ids-components';

// Status modals use the status prop — the icon, colours, and button status are handled automatically. // Use actions instead of footer for opinionated action buttons. <IressModal status="danger" heading="Delete record?" actions={[{ children: 'Cancel', mode: 'tertiary' }, { children: 'Delete' }]} show={isOpen} onShowChange={setIsOpen}

This action cannot be undone. </IressModal>;

Key insight: When status is set on IressModal , the footer prop is not available — use actions instead. Each action button automatically inherits the modal's status. Size is restricted to sm (default) or md .

Figma: Data Table

Figma structure:

• Frame: Table with header row and data rows

• Header: ["Name", "Email", "Status", "Actions"]

• Rows: data with tag in Status column, button in Actions

IDS implementation:

import { IressTable, IressTag, IressButton } from '@iress-oss/ids-components';

function UsersTable({ users }) { return ( <IressTable> <IressTable.Head> <IressTable.Row> <IressTable.HeaderCell>Name</IressTable.HeaderCell> <IressTable.HeaderCell>Email</IressTable.HeaderCell> <IressTable.HeaderCell>Status</IressTable.HeaderCell> <IressTable.HeaderCell>Actions</IressTable.HeaderCell> </IressTable.Row> </IressTable.Head> <IressTable.Body> {users.map((user) => ( <IressTable.Row key={user.id}> <IressTable.Cell>{user.name}</IressTable.Cell> <IressTable.Cell>{user.email}</IressTable.Cell> <IressTable.Cell> <IressTag>{user.status}</IressTag> </IressTable.Cell> <IressTable.Cell> <IressButton mode="tertiary" icon="edit"> Edit </IressButton> </IressTable.Cell> </IressTable.Row> ))} </IressTable.Body> </IressTable> ); }

Responsive Layout

Always produce responsive output, even when Figma only provides a single desktop frame. IDS uses a 12-column grid with 6 breakpoints — every translation should consider how the layout adapts to smaller screens.

Responsive Design Principles

When no mobile Figma frames are provided, apply these principles:

• Identify the primary task — Determine what the user is trying to accomplish on the page (e.g. filling a form, reviewing data, making a decision). The mobile layout should prioritise this task.

• Stack multi-column layouts — Any side-by-side columns should stack to full-width (span={{ xs: 12, md: ... }} ) on mobile.

• Relocate secondary content — Move supplementary UI (filters, sidebars, secondary actions, metadata panels) into an IressSlideout or collapsible section on mobile so the primary task remains front and centre.

• Simplify dense layouts — Tables with many columns, multi-panel dashboards, and wide forms should adapt: hide non-essential columns with hideBelow , collapse sections, or switch to a card-based layout on mobile using useBreakpoint .

• Preserve all functionality — Never remove features on mobile. Use IressSlideout , IressModal , expandable sections, or IressTabSet to keep functionality accessible without cluttering the mobile view.

Breakpoints

Breakpoint Screen width

xs

0 – 575px

sm

576px – 767px

md

768px – 1023px

lg

1024px – 1279px

xl

1280px – 1599px

xxl

1600px+

Responsive Props

Many props accept a ResponsiveProp — either a single value or an object keyed by breakpoint:

// Single value (all breakpoints) <IressCol span={6} />

// Responsive — full-width on mobile, half on medium+ <IressCol span={{ xs: 12, md: 6 }} />

Props that support responsive values: span , offset , gap , gutter , rowGap , p , px , py , pt , pr , pb , pl , m , mx , my , mt , mr , mb , ml , width , srOnly , hideFrom , hideBelow .

Figma Multi-Viewport → Responsive Columns

When Figma provides separate mobile and desktop frames for the same layout:

Figma mobile (xs): Single column stack Figma desktop (md+): Two-column sidebar layout

<IressRow gutter={{ xs: 'sm', md: 'lg' }}> <IressCol span={{ xs: 12, md: 4 }}> <Sidebar /> </IressCol> <IressCol span={{ xs: 12, md: 8 }}> <MainContent /> </IressCol> </IressRow>

Figma Desktop-Only → Inferred Responsive Layout

When Figma only provides a desktop frame with a sidebar + main content area, infer the mobile layout:

import { useBreakpoint, IressSlideout, IressButton, IressRow, IressCol } from '@iress-oss/ids-components';

function Page() { const { breakpoint } = useBreakpoint(); const isMobile = breakpoint === 'xs' || breakpoint === 'sm'; const [filtersOpen, setFiltersOpen] = useState(false);

return ( <> {isMobile ? ( // Mobile: primary content first, secondary content in slideout <IressStack gap="4"> <IressButton mode="secondary" icon="filter_list" onClick={() => setFiltersOpen(true)}> Filters </IressButton> <MainContent /> <IressSlideout heading="Filters" show={filtersOpen} onShowChange={setFiltersOpen}> <FilterPanel /> </IressSlideout> </IressStack> ) : ( // Desktop: side-by-side layout as designed in Figma <IressRow gutter="lg"> <IressCol span={3}><FilterPanel /></IressCol> <IressCol span={9}><MainContent /></IressCol> </IressRow> )} </> ); }

Responsive Visibility

Use hideFrom /hideBelow CSS props directly on any component:

<IressButton hideBelow="md">Desktop action</IressButton> <IressText hideFrom="lg">Mobile only text</IressText>

For conditional rendering based on breakpoint (e.g. rendering entirely different components), use the useBreakpoint hook:

import { useBreakpoint } from '@iress-oss/ids-components';

function Navigation() { const { breakpoint } = useBreakpoint(); const isMobile = breakpoint === 'xs' || breakpoint === 'sm';

return isMobile ? <MobileNav /> : <DesktopNav />; }

Best Practices

• Use IDS components, not raw elements — IDS components encapsulate correct spacing, colours, border radius, and accessibility

• Don't recreate component internals — If Figma shows a button with specific padding/radius, use IressButton with the right mode — the styling is built in

• Map Figma gap/padding to spacing tokens — Divide pixel value by 4 to get the token number

• Prefer semantic props over manual styling — Use status="danger" instead of bg="colour.system.danger.fill"

• Use IressField for all form inputs — It provides the label, hint, and validation layout

• Respect responsive patterns — Use hideFrom /hideBelow props or the useBreakpoint hook for responsive visibility; use responsive span on IressCol for adaptive grid layouts

• Always make grid layouts responsive — When translating Figma multi-column layouts, use responsive span values (e.g. span={{ xs: 12, md: 6 }} ) so columns stack on mobile

• Check the component docs — Read the specific component doc for detailed props and patterns (node_modules/@iress-oss/ids-components/.ai/components/ )

Common Mistakes

⚠️ AI agents are especially prone to these mistakes because they match patterns found in existing codebases. Always verify against component documentation rather than copying surrounding code.

Do not use slot attributes — use React props instead

The slot attribute (e.g. slot="start" , slot="prepend" ) is a legacy v4 pattern that is no longer supported. IDS v5+ uses typed React props to position content inside components.

// ❌ Wrong — legacy v4 slot attribute <IressButton> <IressIcon slot="start" name="home" /> Home </IressButton>

// ✅ Correct — use prepend prop <IressButton prepend={<IressIcon name="home" />}> Home </IressButton>

Slot → prop mapping: slot="prepend" /slot="start" → prepend={...} , slot="append" /slot="end" → append={...} , slot="icon-only" → icon="name" , slot="footer" → footer={...} or actions={[...]} , slot="activator" → activator={...} .

Do not translate Figma named slots to HTML slot attributes

When Figma shows named content areas ("prepend", "append", "footer"), map them to the corresponding React prop, not to a slot attribute.

⚠️ IressShadow does NOT imply custom elements. If the codebase uses IressShadow , this is a CSS isolation wrapper for microfrontends — it creates a shadow root on a plain <div> . All children inside it are standard React components. Do not translate Figma designs into Web Component or slot patterns because of IressShadow .
