Accessibility for Shopify Liquid Themes

Core Principle

Every interactive component must work with keyboard only, screen readers, and reduced-motion preferences. Start with semantic HTML — add ARIA only when native semantics are insufficient.

Decision Table: Which Pattern?

ComponentHTML ElementARIA PatternReference
Expandable content<details>/<summary>None neededAccordion
Modal/dialog<dialog>aria-modal="true"Modal
Tooltip/popup[popover] attributerole="tooltip" fallbackTooltip
Dropdown menu<nav> + <ul>aria-expanded on triggersNavigation
Tab interface<div>role="tablist/tab/tabpanel"Tabs
Carousel/slider<div>role="region" + aria-roledescriptionCarousel
Product card<article>aria-labelledbyProduct card
Form<form>aria-invalid, aria-describedbyForms
Cart drawer<dialog>Focus trapCart drawer
Price display<span>aria-label for contextPrices
Filters<form> + <fieldset>aria-expanded for disclosuresFilters

Page Structure

Landmarks
html
<body>
<a href="#main-content" class="skip-link">{{ 'accessibility.skip_to_content' | t }}</a>
<header role="banner">
<nav aria-label="{{ 'accessibility.main_navigation' | t }}">...</nav>
</header>
<main id="main-content">
<!-- All page content inside main -->
</main>
<footer role="contentinfo">
<nav aria-label="{{ 'accessibility.footer_navigation' | t }}">...</nav>
</footer>
</body>
  • Single <header>, <main>, <footer> per page
  • Multiple <nav> elements must have distinct aria-label
  • All content must live inside a landmark
Skip Link
css
.skip-link {
position: absolute;
inset-inline-start: -999px;
z-index: 999;
}
.skip-link:focus {
position: fixed;
inset-block-start: 0;
inset-inline-start: 0;
padding: 1rem;
background: var(--color-background);
color: var(--color-foreground);
}
Headings
  • One <h1> per page, never skip levels (h1 → h3)
  • Use real heading elements, not styled divs
  • Template: <h1> is typically the page/product title

Focus Management

Focus Indicators
css
/* All interactive elements */
:focus-visible {
outline: 2px solid rgb(var(--color-focus));
outline-offset: 2px;
}
/* High contrast mode */
@media (forced-colors: active) {
:focus-visible {
outline: 3px solid LinkText;
}
}
  • Minimum 3:1 contrast ratio for focus indicators
  • Use :focus-visible (not :focus) to avoid showing on click
  • Never outline: none without a visible replacement
Focus Trapping (Modals/Drawers)
  • Trap focus inside modals, drawers, and dialogs
  • Return focus to trigger element on close
  • First focusable element gets focus on open
  • Query all focusable elements: a[href], button:not([disabled]), input:not([disabled]), select, textarea, [tabindex]:not([tabindex="-1"])

See focus and keyboard patterns for full FocusTrap implementation.

Component Patterns

Product Card
html
<article class="product-card" aria-labelledby="ProductTitle-{{ product.id }}">
<a href="{{ product.url }}" class="product-card__link" aria-labelledby="ProductTitle-{{ product.id }}">
<img
src="{{ product.featured_image | image_url: width: 400 }}"
alt="{{ product.featured_image.alt | escape }}"
loading="lazy"
width="{{ product.featured_image.width }}"
height="{{ product.featured_image.height }}"
>
</a>
<h3 id="ProductTitle-{{ product.id }}">
<a href="{{ product.url }}">{{ product.title }}</a>
</h3>
<div class="product-card__price" aria-label="{{ 'products.price_label' | t: price: product.price | money }}">
{{ product.price | money }}
</div>
<button
class="product-card__quick-add"
tabindex="-1"
aria-label="{{ 'products.quick_add' | t: title: product.title }}"
>
{{ 'products.add_to_cart' | t }}
</button>
</article>

Rules:

  • Single tab stop per card (the main link)
  • tabindex="-1" on mouse-only shortcuts (quick add)
  • aria-labelledby on <article> pointing to the title
  • Descriptive alt text on images; empty alt="" if decorative
Carousel
html
<div
role="region"
aria-roledescription="carousel"
aria-label="{{ section.settings.heading | escape }}"
>
<div class="carousel__controls">
<button
aria-label="{{ 'accessibility.previous_slide' | t }}"
aria-controls="CarouselSlides-{{ section.id }}"
>{% render 'icon-chevron-left' %}</button>
<button
aria-label="{{ 'accessibility.next_slide' | t }}"
aria-controls="CarouselSlides-{{ section.id }}"
>{% render 'icon-chevron-right' %}</button>
<button
aria-label="{{ 'accessibility.pause_slideshow' | t }}"
aria-pressed="false"
>{% render 'icon-pause' %}</button>
</div>
<div id="CarouselSlides-{{ section.id }}" aria-live="polite">
{% for slide in section.blocks %}
<div
role="group"
aria-roledescription="slide"
aria-label="{{ 'accessibility.slide_n_of_total' | t: n: forloop.index, total: forloop.length }}"
{% unless forloop.first %}aria-hidden="true"{% endunless %}
>
{{ slide.settings.content }}
</div>
{% endfor %}
</div>
</div>

Rules:

  • Auto-rotation minimum 5 seconds, pause on hover/focus
  • Play/pause button required for auto-rotating carousels
  • aria-live="polite" on slide container (set to "off" during auto-rotation)
  • aria-hidden="true" on inactive slides
  • Each slide: role="group" + aria-roledescription="slide"
Modal
html
<dialog
id="Modal-{{ section.id }}"
aria-labelledby="ModalTitle-{{ section.id }}"
aria-modal="true"
>
<div class="modal__header">
<h2 id="ModalTitle-{{ section.id }}">{{ title }}</h2>
<button
type="button"
aria-label="{{ 'accessibility.close' | t }}"
on:click="/closeModal"
>{% render 'icon-close' %}</button>
</div>
<div class="modal__content">
<!-- Content -->
</div>
</dialog>

Rules:

  • Use native <dialog> element
  • aria-labelledby pointing to the title
  • Close on Escape key (native with <dialog>)
  • Focus first interactive element on open
  • Return focus to trigger on close
Cart Drawer

Same as modal pattern but with additional:

  • Live region for cart count updates: <span aria-live="polite" aria-atomic="true">
  • Clear "remove item" buttons with aria-label="{{ 'cart.remove_item' | t: title: item.title }}"
  • Quantity inputs with associated labels
Forms
html
<form action="{{ routes.cart_url }}" method="post">
<div class="form__field">
<label for="Email-{{ section.id }}">{{ 'forms.email' | t }}</label>
<input
type="email"
id="Email-{{ section.id }}"
name="email"
required
aria-required="true"
autocomplete="email"
aria-describedby="EmailError-{{ section.id }}"
>
<p
id="EmailError-{{ section.id }}"
class="form__error"
role="alert"
hidden
>{{ 'forms.email_required' | t }}</p>
</div>
</form>

Rules:

  • Every input has a visible <label> with matching for/id
  • Use <fieldset>/<legend> for radio/checkbox groups
  • Error messages: role="alert" + aria-describedby linking to input
  • aria-invalid="true" on invalid inputs
  • autocomplete attributes on common fields
  • Required fields: required + aria-required="true" + visual indicator
Product Filters
html
<form class="facets">
<div class="facets__group">
<button
type="button"
aria-expanded="false"
aria-controls="FilterColor-{{ section.id }}"
>{{ 'filters.color' | t }}</button>
<fieldset id="FilterColor-{{ section.id }}" hidden>
<legend class="visually-hidden">{{ 'filters.filter_by_color' | t }}</legend>
{% for color in colors %}
<label>
<input type="checkbox" name="filter.color" value="{{ color }}">
{{ color }}
</label>
{% endfor %}
</fieldset>
</div>
<div aria-live="polite" aria-atomic="true">
{{ 'filters.results_count' | t: count: results.size }}
</div>
</form>
Price Display
html
{% if product.compare_at_price > product.price %}
<div class="price" aria-label="{{ 'products.sale_price_label' | t: sale_price: product.price | money, original_price: product.compare_at_price | money }}">
<s aria-hidden="true">{{ product.compare_at_price | money }}</s>
<span>{{ product.price | money }}</span>
</div>
{% else %}
<div class="price">{{ product.price | money }}</div>
{% endif %}
  • Use aria-label to provide full price context (sale vs. original)
  • aria-hidden="true" on the visual strikethrough to avoid duplicate reading
Accordion
html
<details>
<summary>{{ block.settings.heading }}</summary>
<div class="accordion__content">
{{ block.settings.content }}
</div>
</details>

Native <details>/<summary> provides keyboard and screen reader support automatically.

Tabs
html
<div role="tablist" aria-label="{{ 'accessibility.product_tabs' | t }}">
{% for tab in tabs %}
<button
role="tab"
id="Tab-{{ tab.id }}"
aria-selected="{% if forloop.first %}true{% else %}false{% endif %}"
aria-controls="Panel-{{ tab.id }}"
tabindex="{% if forloop.first %}0{% else %}-1{% endif %}"
>{{ tab.title }}</button>
{% endfor %}
</div>
{% for tab in tabs %}
<div
role="tabpanel"
id="Panel-{{ tab.id }}"
aria-labelledby="Tab-{{ tab.id }}"
{% unless forloop.first %}hidden{% endunless %}
tabindex="0"
>{{ tab.content }}</div>
{% endfor %}
  • Arrow keys navigate between tabs (left/right)
  • Only active tab has tabindex="0", others -1
Dropdown Navigation
html
<nav aria-label="{{ 'accessibility.main_navigation' | t }}">
<ul role="list">
{% for link in linklists.main-menu.links %}
<li>
{% if link.links.size > 0 %}
<button aria-expanded="false" aria-controls="Submenu-{{ forloop.index }}">
{{ link.title }}
</button>
<ul id="Submenu-{{ forloop.index }}" hidden role="list">
{% for child in link.links %}
<li><a href="{{ child.url }}">{{ child.title }}</a></li>
{% endfor %}
</ul>
{% else %}
<a href="{{ link.url }}">{{ link.title }}</a>
{% endif %}
</li>
{% endfor %}
</ul>
</nav>
Tooltip
html
<button aria-describedby="Tooltip-{{ block.id }}">
{{ 'labels.info' | t }}
</button>
<div id="Tooltip-{{ block.id }}" role="tooltip" popover>
{{ block.settings.tooltip_text }}
</div>

Mobile Accessibility

  • Touch targets: minimum 44x44px, 8px spacing between targets
  • No orientation lock: never restrict to portrait/landscape
  • No hover-only content: everything accessible via tap
  • Use dvh instead of vh for mobile viewport units

Animation & Motion

css
/* Always provide reduced motion */
@media (prefers-reduced-motion: reduce) {
*, *::before, *::after {
animation-duration: 0.01ms !important;
animation-iteration-count: 1 !important;
transition-duration: 0.01ms !important;
scroll-behavior: auto !important;
}
}
  • No flashing above 3 times per second
  • Auto-playing animations need pause/stop controls
  • Meaningful animations only — don't animate for decoration

Visually Hidden Utility

css
.visually-hidden {
position: absolute;
width: 1px;
height: 1px;
padding: 0;
margin: -1px;
overflow: hidden;
clip: rect(0, 0, 0, 0);
white-space: nowrap;
border: 0;
}

Use for screen-reader-only content like labels and descriptions.
