It emphasizes minimalism and accessibility by avoiding JavaScript dependencies and relying on native CSS features for interaction and animation. The author details the development rationale, design decisions, and implementation specifics, positioning the carousel as a performant and user-friendly option for developers and content creators within the WordPress ecosystem. ## 📖 Main Content: Pascal Birchler introduces the CSS Carousel Block as a solution for embedding carousels in WordPress that are both efficient and accessible. Instead of traditional JavaScript-driven sliders, this block leverages modern CSS features—like `scroll-snap`, transitions, and pseudo-elements—to achieve smooth carousel functionality. This approach reduces complexity, improves load times, and aligns with progressive enhancement principles. The article breaks down the technical structure of the block, including how slide navigation works via CSS controls and the use of input elements to toggle slides. It highlights the block’s responsiveness and keyboard navigability, which bolster accessibility compliance. The author also touches on customizability, allowing users to adapt styling via block controls. Notably, the block integrates seamlessly with the WordPress block editor, supporting dynamic content insertion while maintaining a lightweight footprint. The article encourages developers to consider CSS-first solutions for interactive UI components to improve performance and maintainability. Personal insights include a strong advocacy for avoiding unnecessary JavaScript and a recommendation for building modular, composable blocks that focus on core web technologies. ## 🗒️ Notes - **Concept and Motivation:** - Desire to create a carousel block without JavaScript dependencies - Focus on performance, accessibility, and maintainability - **Technical Implementation:** - Uses CSS `scroll-snap` for smooth slide transitions - Employs hidden radio inputs and labels for slide navigation - Pseudo-elements add navigation arrows and indicators purely in CSS - Transitions and transforms provide animation effects - **Accessibility Features:** - Keyboard navigable through native HTML input controls - Supports screen readers by semantic HTML use - Responsive design adjusts for different viewport sizes - **WordPress Integration:** - Developed as a Gutenberg block for easy insertion and configuration - Customizable via block inspector controls (e.g., number of slides, layout) - Lightweight with no JavaScript overhead improves page speed - **Performance & UX:** - Minimal CSS footprint (~2KB) - No reliance on external libraries or heavy assets - User-friendly controls with visible focus states - **Limitations:** - Some advanced carousel features (e.g., autoplay, infinite loop) require JavaScript - Manual slide selection via radio inputs may not suit all use cases - **Philosophy:** - Advocates for CSS-first UI components - Encourages developers to leverage browser-native capabilities - Suggests modular design in block development ## 📖 References: - Pascal Birchler’s website and article: https://pascalbirchler.com/css-carousel-block/ - WordPress Gutenberg Block Development Resources - CSS Tricks on Scroll Snap: https://css-tricks.com/practical-css-scroll-snap-points/ - MDN Web Docs on CSS Transitions and Pseudo-elements ## 🗣️ Paraphrase: **Paragraph 1 Paraphrase:** Pascal Birchler designed a carousel block for WordPress that operates entirely through CSS, eliminating the need for JavaScript. This approach aims to keep the carousel fast, lightweight, and accessible, while seamlessly fitting into the WordPress block editing experience. **Paragraph 2 Paraphrase:** The carousel’s navigation leverages hidden radio buttons and labels styled with CSS pseudo-elements to create arrows and slide indicators. This technique allows users to switch slides intuitively and supports keyboard navigation without extra scripting, enhancing usability and accessibility. ## 📰 Newsletter: 🚀 **This Week in WordPress Development:** Explore the latest in CSS innovation with Pascal Birchler’s CSS Carousel Block—a smart, JavaScript-free slider that brings performance and accessibility together for Gutenberg users.

I don’t usually write about CSS features, but this one is particularly intriguing because it allows for [pure CSS-based carousels](https://developer.chrome.com/blog/carousels-with-css) — no JavaScript required! Why is this significant? ([View Highlight](https://read.readwise.io/read/01jvyhxaxc0kqg7qct73etqz23)) - **Strong accessibility** Carousel best practices such as keyboard support are handled by the browser, so you don’t have to worry about it. Sure, you might be able to build an equally accessible carousel yourself. However, it would cost you a lot more time (and code). Plus, CSS carousels work even with JavaScript disabled. ([View Highlight](https://read.readwise.io/read/01jvyhxs30shmpt9q2fb1v067p)) - But CSS carousels can do a lot more. If you would like some inspiration, I highly recommend checking out the [Carousel Gallery](https://chrome.dev/carousel/) site with tons of incredible demos. Each demo covers a real use case found on the internet. They all show how to orchestrate scroll buttons and markers with [scroll-driven animations](https://developer.chrome.com/docs/css-ui/scroll-driven-animations), [`scroll-state()` queries](https://developer.chrome.com/blog/css-scroll-state-queries), and much more. Here’s one of the demos of a e-commerce product image gallery using a CSS carousel: ([View Highlight](https://read.readwise.io/read/01jvyhxay6gbm33qz45v9c7xmc))
