Designing for agentic AI requires attention to both the system’s behavior and the transparency of its actions. Between the black box and the data dump lies a more thoughtful approach. Victor Yocco explores how to map decision points and reveal the right moments to build trust through clarity, not noise.

More than a year of iteration, motion studies, and technical refinement went into shaping R—K ’26 into a portfolio where identity, rhythm, and interaction work as one.

That gap between "the form works" and "the business works" is something we don't really tend to discuss much as front-enders. We focus a great deal on user experience, validation methods, and accessibility, yet we overlook what the data does once it leaves our control Form Automation Tips for Happier User and Clients originally published on

Success in modern UX isn’t about having the most content. It’s about having the most findable content. Yet even with more data and better tools than ever, internal search often fails, leaving users to rely on global search engines to find a single page on a local site. Why does the “Big Box” still win, and how can we bring users back?

Accessibility works best when it blends into everyday design workflows. The goal isn’t a big transformation, but simple work processes that fit naturally into a team’s routine. With Figma variables, testing font size increases becomes part of the design flow itself, making accessibility feel almost inevitable rather than optional.

The new CSS corner-shape() property is mathematical, so it’s easily animated. Author Daniel Schwarz pokes at animating the property for interesting UI effects. Experimenting With Scroll-Driven corner-shape Animations originally published on CSS-Tricks, which is part of the

The way JavaScript handles time has evolved significantly, from the built-in `Date` API to Moment.js and now Temporal. The new standard fills gaps in the original `Date` API while addressing limitations found in Moment and other libraries. Joe Attardi shares practical “recipes” for migrating Moment-based code to the new Temporal API.

For years, developers have been hacking around the limitations of `border-radius`, using clip-path, SVG masks, and fragile workarounds just to get anything other than round corners. The new `corner-shape` property finally changes that, opening the door to beveled, scooped, and squircle corners.

Let’s go over a few demos using the new customizable <select> feature that may be wild, but also give us a great chance to learn new things in CSS. Abusing Customizable Selects originally published on CSS-Tricks, which is part of the

Many product teams still lean on usability improvements and isolated behavioral tweaks to address weak activation, drop-offs, and low retention – only to see results plateau or slip into shallow gamification. Anders Toxboe updates persuasive design for today’s reality, clarifying what has actually held up over the last decade.

UX design is entering a new phase, with designers shifting from makers of outputs to directors of intent. AI can now generate wireframes, prototypes, and even design systems in minutes, but UX has never been only about creating interfaces. It’s about navigating ambiguity, advocating for humans in systems optimised for efficiency, and solving their problems through thoughtful design.

Our newest Smashing Book, “Accessible UX Research” by Michele Williams, is finally shipping worldwide — and we couldn’t be happier!

This thoughtful book will get you thinking about ways to make your UX research more inclusive and thorough, no matter your budget or timeline. Jump to the book

What happens if you rebuild a single tooltip using the browser’s native model without the aid of a library? The Popover API turns tooltips from something you simulate into something the browser actually understands. Opening and closing, keyboard interaction, Escape handling, and much of the accessibility now come from the platform itself, not from ad-hoc JavaScript.

Do you need a little inspiration boost? Well, then our new batch of desktop wallpapers is for you. Designed by the community for the community, the wallpapers in this collection are the perfect opportunity to get your desktop ready for spring — and, who knows, maybe they’ll spark some new ideas, too.

Every high-resolution hero image, autoplay video, and complex JavaScript animation carries a cost. Sustainable UX challenges the era of “unlimited pixels” and reframes performance as responsibility. In 2026, truly sophisticated design is defined not by how much it adds, but by how thoughtfully it reduces its footprint.

What makes streaks so powerful and addictive? To design them well, you need to understand how they align with human psychology. Victor Ayomipo breaks down the UX and design principles behind effective streak systems.

AI coding tools like agents can be valuable allies in everyday development work. They help handle time-consuming grunt work, guide you through large legacy codebases, and offer low-risk ways to implement features in previously unfamiliar programming languages. Here are practical, easy-to-apply techniques to help you use these tools to improve your workflow.

In CSS, we can create “stacking contexts” where elements are visually placed one on top of the next in a three-dimensional sense that creates the perception of depth. Stacking contexts are incredibly useful, but they’re also widely misunderstood and often mistakenly created, leading to a slew of layout issues that can be tricky to solve.

Developing effective agentic AI requires a new research playbook. When systems plan, decide, and act on our behalf, UX moves beyond usability testing into the realm of trust, consent, and accountability. Victor Yocco outlines the research methods needed to design agentic AI systems responsibly.

Amit Sheen takes a hard look at the “Pixel Perfect” legacy concept, explaining why it’s failing us and redefining what “perfection” actually looks like in a multi-device, fluid world.
