Pictogram

A pictogram is a <figure> that pairs an icon or illustration with a title and description in a centered or side-by-side layout. The icon is the required focal element; heading and description provide context.

Use it for feature lists, value propositions, "how it works" steps, benefit grids, and any place a small illustrated unit communicates a concept more clearly than text alone.

Example

Pictogram
Show demo markup 
<div class="pictogram" aria-label="an icon-based component pairing an icon with a title and description in a centered or side layout">Pictogram</div>
Usage example 
<script lang="ts">
  import Pictogram from './Pictogram.svelte';
</script>

<Pictogram heading="Privacy" description="Your data stays yours.">
  {#snippet icon()}
    <span aria-hidden="true">🔒</span>
  {/snippet}
</Pictogram>
Show Svelte source 
// In your Svelte component:
import Pictogram from "lily-design-system-svelte-headless/components/Pictogram/Pictogram.svelte";

<Pictogram>
  <!-- content -->
</Pictogram>

Usage

Centered pictogram:

<Pictogram heading="Privacy" description="Your data stays yours.">
  {#snippet icon()}<svg>...</svg>{/snippet}
</Pictogram>

Side layout with custom caption content:

<Pictogram layout="side" heading="Speed">
  {#snippet icon()}<svg>...</svg>{/snippet}
  <p>Loads in under a second on any connection.</p>
</Pictogram>

Props

  • layout: "centered" | "side" (default: "centered") -- icon position
  • heading: string (optional) -- title text
  • description: string (optional) -- body text
  • icon: slot/snippet/ReactNode (required) -- the icon content
  • label: string (optional) -- aria-label override
  • children: slot (optional) -- overrides description if provided
  • ...restProps: any additional HTML attributes

Keyboard Interactions

  • None (passive element); interactive children manage their own keyboard behavior.

ARIA

  • Implicit figure semantics from the <figure> element
  • Icon container is aria-hidden="true" (decorative)
  • Accessible name comes from the heading inside <figcaption> or from label if provided
  • data-layout is a non-ARIA hook for consumer styling

When to Use

  • Use to introduce a feature, value, or step with a meaningful illustration.
  • Use in three-up or four-up grids of capabilities.
  • Use when the visual symbol genuinely aids comprehension.

When Not to Use

  • Do not use for purely decorative imagery without a heading or description — use Image.
  • Do not use to convey critical information via the icon alone — heading and description should carry meaning.
  • Do not put an interactive control in the icon slot; put it in children below the description.

Headless

Renders a <figure> with an aria-hidden icon container, a <figcaption> holding the heading and description (or children). Visual layout, icon sizing, and typography are entirely the consumer's responsibility, with data-layout as a hook for "centered" vs "side" arrangements.

Styles

Consumer CSS targets the pictogram class. Use the data-layout="centered" and data-layout="side" attribute selectors to arrange the icon and caption. Style the inner pictogram-icon, pictogram-caption, pictogram-heading, and pictogram-description classes as needed.

Testing

  • Verify the component renders a <figure> element with class pictogram
  • Verify data-layout reflects the layout prop (default "centered")
  • Verify the icon container has aria-hidden="true" and class pictogram-icon
  • Verify the heading renders inside <figcaption> as <h3 class="pictogram-heading"> when provided
  • Verify the description renders as <p class="pictogram-description"> when provided
  • Verify children replace the description when provided
  • Verify aria-label is rendered when label is provided

Advice

  • Designers: Use a consistent icon family across pictograms in a grid. Maintain a stable caption height to keep grids aligned.
  • Developers: Pass the icon via the dedicated icon slot/prop, not children. This keeps aria-hidden on the icon container without affecting other content.

Implementation Notes

  • Uses a native <figure> element so the icon and caption are grouped semantically
  • icon is required as a slot/snippet/ReactNode — it is NOT children
  • Icon container has aria-hidden="true" because the icon is decorative; the accessible name comes from the heading or label
  • layout is exposed as data-layout ("centered" | "side", default "centered") for consumer styling
  • label is optional and overrides the implicit accessible name
  • children (when provided) override the description in the caption
