<p><strong>Any Block Carousel Slider</strong> is a Gutenberg carousel slider block plugin that instantly converts supported native WordPress blocks (Query Loop/Post Template, Group, Gallery) into a responsive carousel slider without adding a dedicated block or loading a JavaScript library. Simply enable the “Carousel” toggle in the Gutenberg editor: your content stays 100% native, your DOM stays lightweight, and your Lighthouse performance scores remain intact. This includes WooCommerce product listings rendered via the Query Loop/Post Template block, so you can showcase products without relying on the legacy Products block.</p>
<p>Unlike many all-in-one carousel slider blocks that require you to add a dedicated “Carousel” block and rebuild every slide, <strong>Any Block Carousel Slider</strong> hooks straight into the Gutenberg blocks you already use. The result: a Query Loop/Post Template, Group, or Gallery block can become a carousel slider in one click, without content duplication or extra maintenance.</p>
<h4>Why Any Block Carousel Slider instead of a dedicated carousel slider block?</h4>
<ul>
<li><strong>WordPress loops without friction</strong> – Transform Query Loop and Post Template Gutenberg blocks into a “loop slider” without creating a block per slide.</li>
<li><strong>Familiar editorial experience</strong> – Content editors keep the Gutenberg interface they know (patterns, global styles, alignments, inner blocks).</li>
<li><strong>Zero JavaScript on the frontend</strong> – Native scroll, <code>scroll-snap</code>, GPU-friendly, no Swiper/Slick bundle to load.</li>
<li><strong>Full compatibility</strong> – Works with classic themes and block themes while respecting the structure of your Query Loop/Post Template, Group, and Gallery blocks.</li>
<li><strong>Accessibility + SEO</strong> – Keyboard navigation, respects <code>prefers-reduced-motion</code> preferences, clean DOM for crawling.</li>
</ul>
<h4>What you can do in 30 seconds</h4>
<ul>
<li><strong>Blog / Magazine</strong>: Display your latest posts in a Query Loop carousel with native filters and badges.</li>
<li><strong>Portfolios & testimonials</strong>: Keep your Group blocks and make them scrollable without rebuilding every slide.</li>
<li><strong>Advanced galleries</strong>: Turn the Gallery block into a responsive slider while keeping all native settings.</li>
<li><strong>Landing sections</strong>: Chain complex sections (image, title, buttons, forms) inside the same Group block and scroll them horizontally.</li>
<li><strong>WooCommerce highlights</strong>: Use a Query Loop configured for products (featured, on sale, custom taxonomy) and convert it into a CSS-only product carousel.</li>
</ul>
<h4>Quick comparison</h4>
<ul>
<li><strong>Activation</strong>: Any Block Carousel Slider – toggle an existing Gutenberg block. Classic carousel slider blocks – add a dedicated slider block and rebuild every slide.</li>
<li><strong>WordPress loop</strong>: Any Block Carousel Slider – works with Query Loop and Post Template blocks without duplication. Competitor carousels – require one block per slide or custom code.</li>
<li><strong>Frontend JavaScript</strong>: Any Block Carousel Slider – zero JavaScript, 100% CSS carousel slider. Competitor carousels – load Swiper/Slick and additional scripts.</li>
<li><strong>Performance</strong>: Any Block Carousel Slider – lightweight DOM, no external assets. Competitor carousels – multiply files, reflow, and downloads.</li>
<li><strong>Content maintenance</strong>: Any Block Carousel Slider – single Gutenberg block to update. Competitor carousels – duplicate content in dedicated slides.</li>
<li><strong>Security & upkeep</strong>: Any Block Carousel Slider – no third-party libraries to monitor. Competitor carousels – depend on external JS libraries like Swiper/Slick.</li>
</ul>
<h4>Key features</h4>
<ul>
<li><strong>100% CSS</strong> – Smooth carousel slider with <code>scroll-snap</code>, <code>::scroll-button</code>, and <code>::scroll-marker</code>. No script to bundle.</li>
<li><strong>Smart responsive</strong> – Automatically handles visible columns, spacing, and control sizes according to WordPress breakpoints (1280, 1024, 782, 600, 480, 375).</li>
<li><strong>Two width modes</strong> – Manual mode (fixed column count) and Auto mode (fixed width like 320px) with automatic detection.</li>
<li><strong>Gutenberg block spacing detection</strong> – Respects <code>gap</code> and <code>padding</code> values defined in the block editor, including presets.</li>
<li><strong>Theme colors</strong> – Buttons automatically inherit your theme’s colors and radii (via CSS variables).</li>
<li><strong>Intact semantics</strong> – Your Gutenberg block’s tags and classes remain unchanged: perfect for SEO, schemas, and E2E testing.</li>
<li><strong>WooCommerce friendly</strong> – Query Loop can target the <code>product</code> post type, so WooCommerce grids become CSS-only carousels without a dedicated Products block integration.</li>
</ul>
<h4>Native Gutenberg block workflow</h4>
<ol>
<li>Add or edit one of the supported blocks (Gallery, Group, or Query Loop/Post Template).</li>
<li>Enable the <strong>Carousel</strong> option in the Gutenberg sidebar panel (Layout or Block section depending on the block).</li>
<li>Adjust your usual settings (column count, minimum width, spacing, alignment).</li>
<li>Save: your block becomes a touch-friendly, accessible, and SEO-friendly carousel slider.</li>
</ol>
<h4>Advanced customization</h4>
<ul>
<li><strong>Manual mode (fixed columns)</strong> – Ideal for article carousel sliders: 1 to 6 columns depending on screen sizes.</li>
<li><strong>Auto mode (fixed width)</strong> – Perfect for card-based sliders (posts, testimonials, product highlights) with pixel-perfect widths like 280px, 320px, or 360px.</li>
<li><strong>Padding and gaps</strong> – Automatic management via CSS vars <code>--carousel-padding-*</code>, <code>--wp--style--block-gap</code>.</li>
<li><strong>Themes & <code>theme.json</code></strong> – Override variables to align controls with your design system.</li>
<li><strong>Graceful degradation</strong> – If a browser doesn’t support <code>::scroll-button</code>, users keep touch and mouse scrolling.</li>
</ul>
<h4>Technical architecture</h4>
<ul>
<li><code>render_block</code> hook to inject variables based on context (block type, columns, gaps).</li>
<li>Dedicated service for translating labels and help messages.</li>
<li>Separate editor/frontend styles for a transparent Gutenberg experience.</li>
<li>Code organized by PSR-4 services (see <code>ARCHITECTURE.md</code> for details).</li>
</ul>
<h3>How to use the plugin</h3>
