Dice UI: Composable, Unstyled UI Primitives for Building Accessible Web Apps — Currently a modest collection of about 20 React-based components and utilities, including form elements, a Kanban-style board, a sortable component, and more.

CSS Holographic Masks — Christian has been experimenting with some neat holographic effects created with CSS gradients and masks, and shares the results here via various little demos. Scroll to see the shiny stuff in action.

TailwindFlex: A Library of 2,000+ Free Tailwind Examples — This resource includes a few different ways to filter what you’re looking for (e.g. 80+ tags), or you can search by keyword. You can also build your own components using their live playground.

Font Sensei: Google Fonts Categorized by Tag Names — To filter the results there are dozens of tags to choose from, for example high-contrast, all-caps, futuristic, etc., with each tag displaying the number of fonts on that style (e.g. “western 5”).

Item Flow: A New Unified Concept for Layout — You may recall all the debate around 'masonry' layouts in CSS and how best to implement them — now there's a third option in the mix. It’s one that “unifies the flex-flow and grid-auto-flow properties into a whole new mechanism” known as Item Flow. Here’s a look at what it is, plus what it means...

Master Chrome's DevTools — Join Jon Kuperman for this video course diving into Chrome's DevTools. You'll go beyond console.log(), learning how to inspect, debug, and audit your web apps — tracking performance, identifying bottlenecks, making performance gains, and more. Level up your DevTools skills.

Carousels with CSS — As of Chrome 135 you could now, theoretically, ditch the various carousel libraries and make use of new features introduced via CSS Overflow 5. Adam runs through the multitude of options this opens up — meaning we now have tools at our disposal for creating accessible, performant carousels with just CSS. Kevin Powell has also taken a look in this (honestly)...

▶  The Death of the Browser — In ten years, could web browsers become a nostalgic memory? This lightning talk (related slides here) shares our journey from the invention of the browser, to the data arms race, to the dawn of AI agents. Proposing how those agents are possibly enabling a return to the era of free information with the ‘web as the API’.

How AI Agents Are 'Quietly Transforming' Frontend Development — “We’re not far from agents that can run A/B tests, evaluate performance impact, and recommend UX optimizations based on live user data”.

Learn How to Integrate Clerk with Your Lovable — Lovable integrates Clerk for custom domains, streamlined auth flows, and waitlist-powered onboarding.

Expanding CSS Shadow Effects — A solid exploration of CSS shadows, going beyond just basic depth perception. Preethi shares how things like inset box-shadows, filters, layering, and @keyframes can create interesting and dynamic visual effects.

Cowardly Defaults and Courageous Overrides with Modern CSS — A look at how modern CSS techniques can create versatile utility classes that don’t clash with existing styles.

▶  Revisiting Fluid Type — A roughly hour long chat with Richard Rutter of Clearleft about fluid typography, and how a website design should plan for (and respond to) user preferences.

The Systemic Failure of Implementing CSS Principles — On lengthy utility classes: “I believe I am not the only one frustrated with some ‘modern’ approaches to CSS architecture”.

Designers, Your Excuse Is Gone. Stunning, Animated and Accessible. Yes, You Can! — “Accessibility and stunning animated design can go hand in hand”.

Previewing Content Changes in Your Work with document.designMode — A look at several use cases for document.designMode and how it can be used to preview content changes, do basic content editing, and improve team collaboration.

An MCP Server for Playwright and Browser Automation — MCP (Model Context Protocol) servers enable certain LLM-based agents (such as Claude, Claude Code, and Cursor) to perform actions on a system outside of their usual sandbox. This new project from Microsoft enables such LLMs to interact with Web pages in a structured way (much as Playwright lets you do from Python or JavaScript code).

CASCII: A Web-Based ASCII and Unicode Diagram Builder — Imagine something like MS Paint but for text-based drawing. You can switch between ASCII and Unicode modes and enable a background grid for alignment. Export directly to clipboard or in Base64.

Konva: A JavaScript 2D Canvas Library — The native API for Canvas elements is pretty good, but Konva is a popular abstraction that sits on top and provides a more structured way to work with shapes, styling, events, animations, and more (lots of demos with code). It also has extra integration libraries for Vue, Svelte and React.

Fancy Components: A Growing Library of Ready-to-Use Animated React Components — Includes a whole slew of components for doing various text animations, along with others for backgrounds, physics-related animations, SVG filters, and more. Try them out here.

Layered Text Headers — Applying a stroke effect to text across all browsers is possible, but as Chris points out it makes use of a center-aligned look which “looks like 💩” (his words). However, the paint-order property may be worth a look as part of a solution for achieving a similar look.
