This document is a recipe book. Copy these patterns directly. Deviate only when a component's specific purpose genuinely requires it — and document why in a comment.
1. Hero Card
Used for: session identity, presenter identity, location identity — the top-of-page "Is this the right one?" card.
<div class="rounded-xl border border-surface-200-800 bg-surface-50-900 shadow-sm overflow-hidden">
<div class="px-4 pt-4 pb-3 flex flex-col gap-3">
<!-- primary heading (h1 / h2) -->
<h1 class="text-2xl font-bold leading-snug">{name}</h1>
<!-- info chips row -->
<div class="flex flex-wrap gap-2 items-center">
<!-- time chip → primary color -->
<span class="inline-flex items-center gap-1.5 text-sm font-semibold px-3 py-1 rounded-full bg-primary-500/10 text-primary-700 dark:text-primary-300 transition-colors duration-200">
<span class="fas fa-clock text-xs" aria-hidden="true"></span>
Mon, Jan 1 – 2:00 PM
</span>
<!-- room/location chip → tertiary color -->
<span class="inline-flex items-center gap-1.5 text-sm font-semibold px-3 py-1 rounded-full bg-tertiary-500/10 text-tertiary-700 dark:text-tertiary-300 transition-colors duration-200">
<span class="fas fa-map-marker-alt text-xs" aria-hidden="true"></span>
Room 201
</span>
</div>
</div>
</div>
Skeleton loading variant:
<!-- While liveQuery resolves -->
<div class="h-7 w-2/3 bg-surface-200-800 animate-pulse rounded"></div>
<div class="h-5 w-1/2 bg-surface-200-800 animate-pulse rounded-full"></div>
2. Standard Content Card
Used for: description text, notes, secondary info panels.
<div class="rounded-lg border border-surface-200-800 bg-surface-50-900 px-4 py-3">
<!-- optional eyebrow label -->
<span class="text-xs font-bold uppercase tracking-wide opacity-40 block mb-1">Description</span>
<p class="whitespace-pre-wrap text-sm leading-relaxed">{description}</p>
</div>
Variant — inner secondary panel:
<div class="bg-surface-100-900 rounded-lg px-3 py-2">
<!-- inner content -->
</div>
3. Table Row
Used for: session search results tables, any <tbody><tr> list.
<tr
class="relative transition-colors duration-200"
class:opacity-50={obj?.hide}
class:preset-tonal-warning={!obj?.enable}
>
<td>
<a
href="/path/to/{obj.id}"
class="font-bold text-lg hover:text-primary-500 transition-colors duration-200"
>
{obj.name}
</a>
</td>
</tr>
opacity-50for hidden/archived recordspreset-tonal-warningfor disabled (not enabled) records — amber backgroundtransition-colors duration-200on both<tr>and<a>
4. List Item Card
Used for: presentation list items, session details lists, any vertical card stack.
<ul class="space-y-4">
<li class="space-y-3 border border-surface-200-800 bg-surface-50-900 p-4 rounded-xl shadow-sm transition-colors duration-200">
<!-- Card heading bar -->
<h4 class="text-lg font-bold rounded-lg px-3 py-2 bg-surface-100-900 flex flex-wrap items-center gap-2">
{name}
<!-- code/tag badge -->
<span class="text-xs preset-tonal-warning px-2 py-0.5 rounded-md leading-none">
{code}
</span>
</h4>
<!-- Description block -->
<pre class="whitespace-pre-wrap p-3 bg-surface-100-900 rounded-lg text-sm">{description}</pre>
</li>
</ul>
Rules:
- Background goes on
<li>, NOT on<ul> <ul>gets only spacing:space-y-4— never a background color- The
<ul>container in components should haveoverflow-x-auto, notoverflow-x-scroll
5. Info Chips
Time / Date chip (Primary — Teal)
<span class="inline-flex items-center gap-1.5 text-sm font-semibold px-3 py-1 rounded-full bg-primary-500/10 text-primary-700 dark:text-primary-300 transition-colors duration-200">
<span class="fas fa-clock text-xs" aria-hidden="true"></span>
Monday, March 6 – 2:00 PM
</span>
Location / Room chip (Tertiary — Indigo)
<span class="inline-flex items-center gap-1.5 text-sm font-semibold px-3 py-1 rounded-full bg-tertiary-500/10 text-tertiary-700 dark:text-tertiary-300 transition-colors duration-200">
<span class="fas fa-map-marker-alt text-xs" aria-hidden="true"></span>
Main Hall B
</span>
Code / Tag badge
<span class="text-xs preset-tonal-warning px-2 py-0.5 rounded-md leading-none">
{code}
</span>
Status badge (edit mode only)
{#if $ae_loc.edit_mode}
<span class="badge preset-tonal-surface text-xs">code: {obj.code}</span>
{/if}
Success count badge
<span class="badge preset-tonal-success" class:hidden={!fileCount}>
<span class="fas fa-file-alt m-1" aria-hidden="true"></span>
{fileCount}×
</span>
6. Empty State Panel
Used for: "No results found", "No sessions match your search", "Nothing to show yet".
<section
class="preset-tonal-warning p-6 rounded-xl shadow-sm lg:max-w-lg mx-auto"
role="status"
aria-live="polite"
>
<div class="flex flex-col items-center gap-2 text-center">
<span class="fas fa-search text-3xl opacity-50" aria-hidden="true"></span>
<strong class="text-xl">No sessions found</strong>
<p class="text-base opacity-80">
Use the search bar above to find your session.
</p>
</div>
<!-- optional details card -->
<div class="bg-surface-50-900/60 rounded-lg p-3 mt-4">
<span class="text-xs font-bold uppercase tracking-wide opacity-50 block mb-2">Search by any of:</span>
<ul class="space-y-1 text-sm">
<li class="flex items-center gap-1.5">
<span class="fas fa-angle-right text-xs opacity-50" aria-hidden="true"></span>
Session name
</li>
</ul>
</div>
</section>
7. Warning / Error Inline Banners
Used for: disabled records, agreement-required gates.
<!-- Warning (amber — disabled/inactive) -->
<div class="bg-warning-100 p-4 border border-warning-300 rounded-md">
<h2 class="h3">
<span class="fas fa-exclamation-triangle text-warning-500 m-1" aria-hidden="true"></span>
Location Disabled
</h2>
<p>This location is currently disabled.</p>
</div>
<!-- Error (red — blocked/failed) -->
<div class="bg-error-100 p-4 border border-error-300 rounded-md">
<h2 class="h3">
<span class="fas fa-exclamation-triangle text-error-500 m-1" aria-hidden="true"></span>
Presenter Disabled
</h2>
<p>This presenter is currently disabled.</p>
</div>
8. File Upload Zone (Comp_event_files_upload)
The class_li prop styles the outer upload drop zone container:
<Comp_event_files_upload
class_li="border border-surface-200-800 rounded-xl p-4 bg-surface-50-900 hover:bg-surface-100-900 transition-colors duration-200"
link_to_type="event_presenter"
link_to_id={presenter_id}
>
{#snippet label()}
<span>
<div class="text-lg">
<span class="fas fa-upload" aria-hidden="true"></span>
<strong>Upload presenter files</strong>
</div>
<div class="text-sm opacity-60 italic">
Supported: pptx, key, mp4, pdf, docx, xlsx, txt
</div>
</span>
{/snippet}
</Comp_event_files_upload>
Note: The label sub-description text uses opacity-60 italic — never text-gray-600 dark:text-gray-400.
9. Section Component Wrapper
Used for: ae_comp__event_*_obj_li.svelte outer <section> elements.
<section
class="ae_comp event_X_obj_li px-0.5 py-2 space-y-2 min-w-full w-full container overflow-x-auto {container_class_li}"
>
Rules:
overflow-x-auto— neveroverflow-x-scroll- Never include debug breakpoint borders — remove before committing:
sm:border-l-red-400 md:border-l-yellow-400 lg:border-l-gray-100 sm:dark:border-l-red-600 md:dark:border-l-yellow-600 lg:dark:border-l-gray-700 border-dashed border-y-transparent border-r-transparent
10. Agreement / Consent Form Layout
Used for: ae_comp__event_presenter_form_agree.svelte, ae_comp__event_session_poc_form_agree.svelte.
<!-- Consent text container -->
<div class="bg-surface-100-900 p-4 border border-surface-200-800 rounded-lg space-y-4">
<Element_data_store ds_code="consent_text" ds_type="html" class_li="p-2" />
</div>
<!-- Presenter name/identity highlight line -->
<p class="text-lg preset-tonal-warning p-2 rounded-t-md">
<strong>{presenter_name} ({email})</strong>
agrees to the following terms and conditions:
</p>
11. Modal Usage (Flowbite-Svelte)
<!-- ✅ Correct — no manual color class; theme handles styling -->
<Modal title="Host Profile" bind:open={show_modal}>
<ProfileComponent />
{#snippet footer()}
<button onclick={() => show_modal = false} class="btn preset-tonal-warning">
Close
</button>
{/snippet}
</Modal>
<!-- ❌ Wrong — manual gray overrides bypass the theme -->
<Modal class="bg-white dark:bg-gray-800 text-gray-800 dark:text-gray-200 ...">
Rule: Never set bg-* or text-* color classes on <Modal>. Let the Flowbite component + active theme handle it. Only structural layout classes (shadow-md, relative, flex, etc.) belong on the class prop if needed.
12. Muted / Secondary Text
Replace all text-gray-* patterns with opacity wrappers on inherited text color:
<!-- ✅ Theme-aware muted text -->
<span class="text-sm opacity-60">Secondary label</span>
<span class="text-sm opacity-40 italic">Hint or placeholder text</span>
<span class="text-xs font-bold uppercase tracking-wide opacity-40">Section eyebrow</span>
<!-- ❌ Fixed-color muted text -->
<span class="text-sm text-gray-500">Secondary label</span>
<span class="text-sm text-gray-600 dark:text-gray-400 italic">Hint text</span>
13. QR Code (Async Toggle)
<!-- Gate on typeof === 'string', not truthy.
The store holds boolean `true` as a loading placeholder, which would
render as a broken <img src="true"> if not guarded. -->
{#if $lq__obj && typeof $store.qr_url?.[$lq__obj.id] === 'string'}
<div class="float-right ml-3 mb-1 flex flex-col items-center gap-1">
<button
type="button"
onclick={() => $store.qr_bigger = !$store.qr_bigger}
class="rounded focus-visible:ring-2 focus-visible:ring-primary-500"
title="Toggle QR code size"
aria-label="Toggle QR code size"
>
<img
src={$store.qr_url[$lq__obj.id]}
class="transition-all duration-500 rounded border border-surface-200-800"
class:h-20={!$store.qr_bigger}
class:w-20={!$store.qr_bigger}
class:h-40={$store.qr_bigger}
class:w-40={$store.qr_bigger}
alt="QR code link to this page"
/>
</button>
</div>
{/if}
14. POC / Host Button Pattern
<div class="flex items-center gap-2">
<span class="text-sm font-semibold opacity-60">Host:</span>
<button
type="button"
class="btn btn-sm preset-tonal-primary transition-colors duration-200"
onclick={() => show_profile = true}
aria-haspopup="dialog"
>
<span class="fas fa-id-card mr-1" aria-hidden="true"></span>
{full_name}
</button>
</div>
15. Icon Usage Rules
| Context | Pattern |
|---|---|
| Decorative / visual only | <span class="fas fa-clock" aria-hidden="true"></span> |
| Icon with visible adjacent text | aria-hidden="true" on icon, text provides meaning |
| Icon-only button (no visible text) | aria-label="Description" on the <button> |
| Icon used as bullet point | aria-hidden="true" on icon |
Never use <i> tags. Always <span class="fas ...">.
16. Native <select> Dark Mode
Browser-native <select> and <option> elements cannot be reliably styled with Tailwind dark: utilities — the browser controls <option> rendering and ignores most CSS overrides. This causes the "light on light hover" bug in dark mode.
Fix — add color-scheme directive to force OS-level dark styling:
<script>
import { ae_loc } from '$lib/ae_core/ae_stores';
</script>
<!-- Forces browser to render the select widget in dark/light OS mode matching your theme -->
<select
class="select text-xs p-1"
style:color-scheme={$ae_loc.dark_mode ? 'dark' : 'light'}
>
{#each options as opt}
<option value={opt.value}>{opt.label}</option>
{/each}
</select>
Why this works: color-scheme: dark instructs the browser to use its native dark-mode widget rendering (dark <select>, dark <option> backgrounds). It's the only cross-browser mechanism that affects <option> hover colors.
Alternative — replace with custom Skeleton/Flowbite component if you need full styling control (e.g., color-coded options, icons). Native <select> is acceptable for simple purpose dropdowns with the color-scheme fix above.
Store reference: $ae_loc.dark_mode — boolean, set by the theme engine in ae_stores.ts.
