About this plugin
🧱 Etu Blocks is a focused, accessible block library — and all of it is free.
1. Accessible by construction. 2 Level AA — real dialog semantics, real range inputs, real focus management, real ARIA state that can’t drift from what you see.
Accessibility is a merge gate, not a polish pass.
2. Interactive without bloat. Front-end behaviour runs on the native WordPress Interactivity API — no jQuery, no framework runtime, no build system on your visitors’ pages.
Each block’s script loads only where it’s used, and the content is server-rendered first, so it works even before that script loads — or if it never does.
Etu Blocks does not reinvent core blocks — it builds only what core has no equal for, held to a premium bar: shared design tokens, a schema-driven Inspector every block inherits, and multiple presets per block.
This plugin is free, in full.
No locked panels, no “upgrade to unlock”, no nag screens, no paywall — every block and every control described here works for everyone.
An Etu Blocks Pro add-on with additional premium blocks may follow, but nothing in this free plugin will move behind a paywall.
How Etu Blocks is organised
- Accessible by default — WCAG 2.2 AA is the definition of done
- Interactivity API only — server-rendered first, no framework runtime on visitors’ pages
- Privacy first — video and map embeds use a click-to-load facade; no telemetry, no phone-home
Etu Blocks ships 29 blocks across Content, Marketing, Interactive, Data, and Media groups. Every block is browsable in the editor inserter, with a full description and preview shown inline as you insert it.
🧱 The Blocks
Content
- ❓ FAQ / Accordion — the disclosure pattern, done right: each header is a real <button> inside a heading, aria-expanded reflects state, the panel is a <region> labelled by its button, and closed panels are hidden (not just clipped). Multiple presets, and an optional FAQPage JSON-LD schema for SEO.
- 🗂️ Tabs — a full ARIA Tabs implementation: role="tablist" / role="tab" / role="tabpanel", single-tab-stop keyboard navigation with arrow keys, Home/End, and roving tabindex. Built to the pattern so a future core Tabs block is a trivial transform away.
- 💡 Info Box — icon + heading + text callout with premium presets. The icon is decorative ( aria-hidden ) when text carries the meaning, so screen readers aren’t read a decorative glyph.
- 🎯 Banner — a premium hero: background colour or image with a colour overlay, headline, text, and up to two buttons, with height, alignment, and content-width controls. Buttons render as real <a> links when a URL is set, or focusable <button> elements when not — never inert spans.
- 📢 Call to Action — heading, text, and buttons in a bold section, with the same real-link-or-real-button rule as Banner.
- 💬 Testimonial — quote card with avatar and citation, on semantic <figure> / <blockquote> / <figcaption>. Multiple presets.
- 👥 Team Member — profile card with Card, Overlay, Horizontal, and Minimal presets. Social links are real <a> elements with accessible names, never icon-only.
- 📋 Icon List — feature or checklist list with per-item icons. Real <ul> semantics — a screen reader announces “list, 5 items”.
Marketing
- 💳 Pricing Table — premium plan cards with a featured plan, feature lists, and an optional monthly/annual billing toggle. The toggle is a keyboard-operable radio group (not a fake switch), and the recommended plan is marked with a text badge — never colour alone.
- ⚖️ Comparison Table — compare plans or products side-by-side, with a highlighted column, check/cross/text cells, and a real <table> with <th scope> headers so the row/column relationships are announced correctly.
- 🖼️ Post Grid — display posts as a grid, masonry, or carousel with full query controls (post type, categories, order, offset, exclude-current), premium card presets (Elevated, Bordered, Minimal, Overlay), an optional category filter bar, and carousel controls that respect reduced motion.
- 🏷️ Taxonomy — a visual term browser for any public taxonomy: image-card grid, list, or pill layout. Each card uses the term’s own image or the latest post’s featured image as a universal fallback, cached in a transient so it isn’t re-queried on every page load.
Interactive
- 🪟 Modal / Popup — an accessible dialog: role="dialog" + aria-modal, focus trapped while open and restored to the trigger on close, Esc closes, backdrop dismiss is opt-in, body scroll is locked, and the background is made inert so assistive tech and keyboard focus can only reach the dialog. Opens on click, on page load, or after a delay; holds any blocks.
- 🎬 Video Popup — a video lightbox on the same accessible dialog recipe, with a privacy-first click-to-load facade: the YouTube (via youtube-nocookie.com ), Vimeo (with dnt=1 ), or self-hosted video is requested only when the visitor opens it — no third-party requests, cookies, or autoplay on page view — and closing actually stops playback. Focus is moved in and returned.
- 🎠 Slides / Carousel — put any blocks in each slide; a genuine keyboard-scrollable region (nothing hidden from screen readers), with real prev/next and dot controls, arrows, opt-in autoplay that ships a real pause button and never runs under reduced motion.
- 🔀 Before / After — an image comparison you can operate with the keyboard, not just the mouse. Built on a real <input type="range">, so arrow keys move the divider, dragging works, and the position is announced as a percentage via aria-valuetext. Horizontal or vertical.
- ⏳ Countdown — a countdown to a fixed date or an evergreen per-visitor duration. The ticking digits are hidden from screen readers, so a screen-reader user isn’t read a new number every second, while a role="timer" container carries a descriptive label and the end is announced once via a polite live region.
- 🔍 Post Filter — a filterable post grid: a search field, taxonomy dropdowns, and a reset button. Filtering happens live over a REST endpoint ( etu/v1/posts ) — but the bar is a real GET <form> and Load-more is a real link, so everything works with JavaScript disabled. Card and Overlay presets, with an inline SVG placeholder for posts that have no featured image.
- 🧭 Table of Contents — auto-built from your headings, as a real <nav> landmark. Multiple presets, an optional collapse, sticky positioning, smooth scroll with reduced-motion respect, and active-section highlighting as you scroll.
- 🔗 Social Share — accessible share buttons (social networks, copy link, native device share) on real <a> / <button> elements with accessible names, powered by the Interactivity API.
- 🔔 Notice — dismissible callout, inline or as a fixed top/bottom announcement bar. Persistent dismissal via localStorage so it doesn’t reappear on the next page load.
- 🔢 Counter — an animated number that counts up when it scrolls into view. The final value is present in the DOM immediately for search engines and no-JS visitors; under reduced motion the animation is skipped and the final value stays put.
- 📈 Progress Bar — labelled progress meter with role="progressbar" and aria-valuenow, animated to its target when scrolled into view, still under reduced motion.
- ⭐ Star Rating — an accessible rating display, exposed to screen readers as “Rated 4.5 out of 5” rather than five unlabelled symbols.
- 👣 Steps — numbered process list.
- 📅 Timeline — dated vertical timeline.
Data
- 📊 Data Table — a real, optionally sortable <table> with a <caption>, <th scope="col"> headers, sort changes announced via aria-sort, live search with a polite result count, sticky header, striped/bordered/compact styles, and a focusable scroll region for narrow screens (or a stack-to-cards mode).
Media & integrations
- 📍 Google Map — a keyless Google Maps embed (no API key to configure or leak) with a privacy-first click-to-load facade, a floating info card with title + address, and a keyless “Get directions” link. Road / Satellite / Hybrid / Terrain, aspect ratios, and an optional colour-on-hover grayscale.
- 🎞️ Lottie — plays a Lottie animation with autoplay, on-scroll, hover/focus, or click triggers. Supports both.json and.lottie (dotLottie) — the archive is fetched and unzipped in the browser. Player is bundled, not loaded from a CDN. Reduced motion suppresses auto triggers and leaves a still first frame; hover and click stay available. Uploads: a small helper class lets logged-in editors upload.json and.lottie files to the Media Library (safely — a non-JSON file smuggled as.json is rejected).

External Services
Etu Blocks itself sends no data anywhere. There is no telemetry, no account, and no phone-home. However, several blocks can embed third-party content — and only then, and only in a visitor’s browser:
Google Maps — Google Map block (only when the map is loaded)
com/maps/dir/ ). The block ships a privacy-first click-to-load facade by default, so no request is made to Google until the visitor clicks “Load map”. A site owner can turn this facade off per block to load the map on page view instead.
Data sent: the location (address or place name) the site owner typed into the block, plus what the visitor’s browser normally sends to any embedded iframe (IP address, user agent, cookies).
Sent when: only when the visitor clicks “Load map” (default), or on page view if the site owner disabled the facade. A page with no Map block contacts no external service.
com
com/maps-platform/terms
com/privacy
YouTube — Video Popup block (only when a visitor plays a YouTube video)
com/ — but only when the visitor clicks Play, never on page load. Closing the popup clears the iframe so playback stops entirely.
Data sent: the video ID the site owner entered, plus what the visitor’s browser normally sends to an embedded iframe.
Sent when: only when a visitor opens a Video Popup that points at a YouTube URL.

com/t/terms

Vimeo — Video Popup block (only when a visitor plays a Vimeo video)
com/ with the “do not track” ( dnt=1 ) flag set — but only when the visitor clicks Play, never on page load.
Data sent: the video ID the site owner entered, plus what the visitor’s browser normally sends to an embedded iframe.
Sent when: only when a visitor opens a Video Popup that points at a Vimeo URL. A self-hosted video file, or a popup no visitor opens, contacts no external service.

Author-supplied Lottie animation URLs — Lottie block (only when the site owner uses a remote URL)
lottie file directly from that host to render the animation. lottie file to the site’s Media Library instead avoids any third-party request.
Data sent: nothing beyond the URL request itself and normal browser headers.
Sent when: only when a page contains a Lottie block configured with a remote URL, and only for that URL. Local uploads contact no external service.
g. host)
Terms of Service and Privacy Policy: those of the chosen host.
Social share destinations — Social Share block (only when a visitor clicks a share button)
The Social Share block renders a row of buttons as plain outbound links to each network’s public share URL. Nothing is sent unless a visitor clicks one — the block does not embed any third-party content or make any request on page load. Which networks appear is controlled by the site owner.
Data sent: the URL and title of the page being shared, in the destination network’s public share URL scheme.
Sent when: only when a visitor clicks the corresponding button, in their own browser, opening the network’s share dialog in a new tab.
