The goal of content design is to reduce confusion and improve clarity. Yet often it’s difficult to pinpoint a problem as user feedback tends to be not specific enough. But: we can use a few simple techniques to assess how users understand and perceive content. Let’s take a look. Part of [How To Measure UX & Design Impact](https://measure-ux.com/) by yours truly.

Optimizing web performance means looking beyond surface-level metrics. Time to First Byte (TTFB) is crucial, but improving it requires more than tweaking server response time. Matt Zeunert breaks down what TTFB is, what causes its poor score, and why reducing server response time alone isn’t enough for optimization and often won’t be the most impactful change you can make to your website.

Tomasz Jakut reflects on the evolution of web design, from the days of table-based layouts and Flash games to the rise of responsive web design (RWD), which often feels like the end of history in web layout. But as 2025 marks the 15th anniversary of Ethan Marcotte’s article, it’s worth asking whether something significant happened after RWD — something so seamless that it went almost unnoticed.

In today’s web development landscape, the concept of a monolithic application has become increasingly rare. Modern applications are composed of multiple specialized services, each of which handles specific aspects of functionality. This shift didn’t happen overnight - it’s the result of decades of evolution in how we think about and implement data transfer between systems. Let’s explore this journey and see how it shapes modern architectures, particularly in the context of headless CMS solutions.

Design systems play a crucial role in today’s digital landscape, providing a blueprint for consistent and user-friendly interfaces. But there’s another tool that deserves equal attention: the digital playbook.

It’s not always the big features that make our everyday lives easier; sometimes, it’s those ease-of-life features that truly enhance our projects. In this article, Brecht De Ruyte highlights two such features: `@starting-style` and `transition-behavior` — two properties that are absolutely welcome additions to your everyday work with CSS animations.

After months of anticipation, debate, and even a bit of apprehension, Svelte 5 arrived earlier this year. Frederick O’Brien caught up with its creator, Rich Harris, to talk about the path that brought him and his team here and what lies ahead.

A once-revered perk of some tech workplaces, the status of ‘side project time’ seems to have slipped in recent years. Frederick O’Brien believes it deserves a comeback.

Shouldn’t there be a way to keep your apps or project data private and improve performance by reducing server latency? This is what on-device AI is designed to solve. It handles AI processing locally, right on your device, without connecting to the internet and sending data to the cloud. In this article, Joas Pambou explains what on-device AI is, why it’s important, the tools to build this type of technology, and how it can change the way we use technology every day.

How do we determine the most suitable illustration style? How should illustrations complement and reflect your corporate identity? What will resonate most with your target audience?

The best and worst thing about solo development is the “solo” part. There’s a lot of freedom in working alone, and that freedom can be inspiring, but it can also become a debilitating hindrance to productivity and progress. Victor Ayomipo shares his personal lessons on what it takes to navigate solo development and build the “right” app.

We know that browsers do all sorts of different things under the hood. One of those things is the way they not only *fetch* resources like images and scripts from the server but how they [prioritize those resources](https://www.debugbear.com/blog/request-priorities?utm_campaign=sm-7). Chrome and Safari have implemented a “Tight Mode” that constrains which resources are loaded and in what order, but they each take drastically different approaches to it. With so little information about Tight Mode available, this article attempts a high-level explanation of what it is, what triggers it, and how it is treated differently in major browsers.

HTML attributes are like little instructions that we add to the markup of elements to make them do certain things or behave in certain ways. For example, most of us know that the `target` attribute with a value of `_blank` opens the link in a new tab or window. But did you know that you can use it on the `form` element, too? John Rhea presents several lesser-known uses for common HTML attributes.

Product drops and sales are a great way to increase revenue, but these events can result in traffic spikes that affect a site’s availability and performance. To prevent website crashes, you’ll have to make sure that the sites you design can handle large numbers of server requests at once. Let’s discuss how!

We, as human beings, don’t worry too much about making sure the connections land at the right point. Our brain just works that way, declaratively. However, for building AI, we need to be more explicit. Let’s dive in!

Searching for the most flexible front-end workflows and toolkits, it’s easy to forget how powerful some of the fundamentals on the web have become these days. This post is a journey through new front-end features and what they are capable of.

There are many ways to elevate a design project from good to incredible. For web and product designers, it’s not just about adding more animations and flair. What it truly comes down to is a reframing of your thought processes starting before the project even kicks off. Olivia De Alba presents three approaches that designers can implement and which will change the way they make their projects more successful.

10 years after scroll-driven animations were first proposed, they’re finally here — no JavaScript, no dependencies, no libraries, just pure CSS.

Few things are as frustrating to a user as when a site won’t respond. Unfortunately, it’s also an all-too-common scenario. Many websites and apps depend on so many elements that one of any number of errors could cause the whole thing to fail. As prevalent as such instances may be, they’re preventable through the practice of graceful degradation.

Forms are already notoriously tough to customize and style — to the extent that we’re already starting to see new ideas for more flexible control. But what we don’t often discuss is designing good-form experiences beyond validation. That’s what Jima Victor discusses in this article, focusing specifically on creating multi-step forms that involve navigation between sections.

RSS is a classic technology that fetches content from websites and feeds it to anyone who subscribes to it with a URL. It’s based on XML, and we can use it to consume the feeds in our own apps. Karin Hendrikse demonstrates how to do exactly that with a static site you can use as your personal RSS reader.
