Design always starts with function — function shapes form. But if that function can’t be made completely invisible and people still have to interact with it, it inevitably becomes part of their experience. In this article, Kyrylo Levashov shares four common software design assumptions.

Streaming UIs are an easy concept on the surface, but are quite complicated in practice. There are many considerations that need to be accounted for, from layout shifts and motion preferences to proper markup and various states, that may not be instantly obvious. What happens if the stream is interrupted? Can users tab through the UI on the keyboard as it shifts? What ARIA attributes might be needed?

AI tools are eliminating the need to “bug” colleagues for help, but the informal interactions they replace are the very scaffolding that builds team trust, belonging, and innovation. Casey Hudetz and Eric Olive explore the research and potential impacts behind that risk and offer practical strategies for maintaining human connection while leveraging AI’s strengths.

Behind every technology, there should be a guide for its use.

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.

With the new month just around the corner, could there be a better occasion to freshen up your desktop? If you’re looking for some unique and inspiring wallpapers to accompany you on all those adventures that April may bring — and maybe spark some new ideas, too — well, this post has got you covered.

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.

How to choose between modals and pages, when to avoid modals, and how to determine the right level of interruption or navigation. Brought to you by Smart Interface Design Patterns, a **friendly video course on UX** and design patterns by Vitaly.

Design is about pacing and feelings as much as pixels and patterns. Alan Cohen explores Emotion in Flow and Emotion in Conflict, showing how anime like Dan Da Dan and superhero films like James Gunn’s Superman manage emotional shifts and translating those ideas into practical patterns for product design.

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.

Some forms stay UI, while others quietly become rule engines. Here’s why these two different approaches exist and how to choose between them.

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 book is about research, but you’ll also learn about assistive technology, different types of disability, and how to build accessibility into the entire design process. 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.

Meet our brand new conference for designers and UI engineers who love the web. That’s [SmashingConf Amsterdam](https://smashingconf.com/amsterdam-2026), taking place in the legendary Pathé Tuschinski, on April 13–16, 2026.

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.

Designing for mental health means designing for vulnerability. Empathy-Centred UX becomes not a “nice to have” but a fundamental design requirement. Here’s a practical framework for building trust-first mental health products.

Autonomy is an output of a technical system. Trustworthiness is an output of a design process. Here are concrete design patterns, operational frameworks, and organizational practices for building agentic systems that are not only powerful but also transparent, controllable, and trustworthy.

Prescriptive class name conventions are no longer enough to keep CSS maintainable in a world of increasingly complex interfaces. Can the new `@scope` rule finally give developers the confidence to write CSS that can keep up with modern front ends?

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.

CSS relative colour values are now widely supported. In this article, pioneering author and web designer [Andy Clarke](https://stuffandnonsense.co.uk/) shares practical techniques for using them to theme and animate SVG graphics.

Most developers spend their days fixing bugs, shipping features, and jumping into the next sprint without even thinking about it. After a while, you begin to ask yourself, “Is this still what I want to be doing?” This article looks at how you can move into a new direction in your career without starting from scratch, and how the skills you already use, like problem-solving, communication, and empathy, can open new doors.
