Vercel, the cloud platform behind Next.js, has released react-best-practices, an open-source repository containing over 40 performance optimization rules for React and Next.js applications. The framework, which encapsulates over a decade of engineering knowledge from Vercel's production codebases, is structured specifically for consumption by AI coding agents and LLMs, though the team notes it is equally valuable for human developers.
As the HTTP Archive reminds us, video and audio files are some of the heaviest resources requested by web pages. This new standard will dramatically reduce page weight and ease resource overhead all through a simple declarative HTML attribute. Lazy audio and video works just like lazy-loading of image and iframe elements work today: just add loading=
A JavaScript script saved as a bookmark is called a 'bookmarklet,' although some people also use the term 'favelet' or 'favlet.' Bookmarklets have been around since the late 90s. The site that coined them, bookmarklets.com, even remains around today. They're simple and versatile, a fact evidenced by most of the bookmarklets listed on the aforementioned site are still working today despite being untouched for over two decades.

The group, including Apple, Google, Igalia, Microsoft, and Mozilla, takes proposals of features that are well defined in a sufficiently stable web standard, and have good test suite coverage. Then, we come up with a subset of those proposals that balances web developer priorities (via surveys and bug reports) with our collective resources. We focus on features that are well-represented in Web Platform Tests as the pass-rate is how we measure progress, which you can track on the Interop dashboard.
Here's a really quick tip. You can think of Tailwind utilities as components - because you can literally make a card "component" out of Tailwind utilities. @utility card { border: 1px solid black; padding: 1rlh; } This blurs the line between "Components" and "Utilities" so we need to better define those terms. The Great Divide - and The Great Unification
Aurora OS.js isn't just a web-based OS. It's a portal. Born from the intersection of digital art and cyberpunk culture, this project reimagines the operating system as an immersive game world. It is a high-fidelity hacking simulator built on modern web technologies (React, Vite, Electron), designed to blur the line between utility and gameplay. Currently in its pre-Alpha stage, it serves as the foundation for a future MMO hacking universe - a persistent world where you script, hack, and uncover the lore
As I understand, we have GTM credentials and connects website using the default scripts. When I try to connect the API and GTM, how to put credentials into WordPress to show weather conditions? <script> ! function(e, t, a, n) { e[n] = e[n] || [], e[n].push({ "gtm.start": (new Date).getTime(), event: "gtm.js" }), n = t.getElementsByTagName(a)[0], (a = t.createElement(a)).async = !0, a.src = "https://www.googletagmanager.com/gtm.js?id=GTM-XYZ", n.parentNode.insertBefore(a, n) }(window, document, "script", "dataLayer"); </script>
There have been a few drafts of a specification function for this functionality, most recently, contrast-color() (formerly color-contrast()) in the CSS Color Module Level 5 draft. But with Safari and Firefox being the only browsers that have implemented it so far, the final version of this functionality is likely still a ways off. There has been a lot of functionality added to CSS in the meantime; enough that I wanted to see whether we could implement it in a cross-browser friendly way today. Here's what I have: color: oklch(from <your color> round(1.21 - L) 0 0);
A2UI (Agent to UI) is a UI protocol from Google that lets AI agents generate user interfaces on demand. It introduces declarative mini-apps where UI components and actions are defined in a schema, and the agent can operate them automatically. Think Telegram-style mini-apps: small, self-contained interfaces that work without custom integration code. Instead of a long question-and-answer loop, agents can now send interactive, native interfaces directly to the client.
Every embedded video comes with a real cost to page load performance. Each player loads extra resources, whether the user ever hits play or not, as Chris Coyier noted in his blog post on "YouTube Embeds are Bananas Heavy and it's Fixable". The approach of using in that article works well when the video appears further down on the page and loads outside of the initial viewport. If the video is directly in the initial viewport, it can still cause a cumulative layout shift (CLS).
Welcome to The CSS Selection 2026! In this article we're having a look at how CSS is used at scale on over 100,000 websites. We'll look at what things are common on most websites and discover interesting outliers. This is the first edition of what I hope to be many, so this is meant as a baseline for future editions, setting up the first numbers to compare with in coming years.
Good morning, programs! Today I'm sharing yet another example of Chrome's on-device AI features, this time to demonstrate a "Bluesky Sentiment Dashboard". In other words, a tool that lets you enter terms and then get a report on the average sentiment for posts using that word. I actually did this before (and yes, I forgot until about a minute ago) last year using Transformers.js: Building a Bluesky AI Sentiment Analysis Dashboard.

Web development is an ever-evolving industry. That means we're constantly adapting to what's new, all while maintaining quality and efficiency. No sooner are we comfortable with something than it changes on us. This applies to our workflow just as much as it does to other parts of our business. The way we build websites must align with modern best practices. The good news is that you don't have to scrap your tried-and-true processes. Rather, it's about adjusting to your project's needs.
The Role As a Full Stack Engineer with expertise in .NET and Vue, you'll take on a hands-on role in building web applications while working vertically in both the frontend and the backend. Your responsibilities will involve designing, developing, and fine-tuning web applications, using .NET 6+, MediaTR, EF.Core and VueJS 2/3 to create engaging and user-friendly interfaces. You'll work closely with the client's team to deliver a solution that meets their requirements.
"Link rot" is the unfortunate phenomenon whereby online articles become populated by broken links - URLs that once led to active pages but now result in error messages or dead ends. A Pew Research study from 2024 showed that nearly 40% of links that existed in 2013 were no longer active. Such "digital decay" occurs across a broad diversity of webpages, from news and government sites to Wikipedia pages to tweets.
By AI website builders have stopped being a novelty. They're tools now. Real ones that save hours of work and produce sites that don't look like templates from 2015. The tech got good enough that you can describe your business in a few sentences and have a working site in under an hour. No coding. No template hunting. The AI handles structure, writes copy, picks colors, and suggests images.
The web is full of AI assistants that appear to understand application UIs, user data, and intent. In practice, however, most of these systems operate outside the application itself. When you try to build one from scratch, you quickly run into a core limitation: large language models have no native understanding of your React state, component hierarchy, or business logic.
Can you formulate the css code to apply the glassmorphism (GM) effect b/g to the tasks below: Glassmorphism code snippet background: rgba(255, 255, 255, 0.2); backdrop-filter: blur(5px); border: 1px solid rgba(255, 255, 255, 0.1); 1.1 Apply the GM effect to the Share B/G, Gallery B/G & Vid B/G icons during onmouseout. 1.2 Apply the GM effect to the Social icons pop-up panel B/G during onmousehover on the Share icon.
As a contracting front-end developer and Design Systems consultant, I don't always get to work on new things. Sometimes I work within codebases. Sometimes alongside them. Sometimes these codebases are years and years old. When you dive into these projects, you're not just reading code, you're excavating years of decisions, technological limitations, and creative workarounds from days gone by. Over the last decade, I've called this Front-End Archaeology.
We're looking for a creative and self-sufficient Front-End Developer who loves building exceptional user experiences using the Vue ecosystem. You'll join a cross-functional team working on a complex, modular platform that combines SSR apps, embedded widgets, and AI-powered features. If you thrive in an environment where challenges appear daily - and you enjoy turning chaos into clarity - this is your place.
After searching and searching, it seems that you and I are the only ones in the world who have this problem. In the F12 console, I found: SEC7113 "CSS was ignored due to mime type mismatch". Discussion here: MSDN. It seems that IE9 and above "sniff" the HTTP headers for the correct MIME type, and ignore JS and CSS that have the wrong header. When it fetches files from the local filesystem, it should disable this sniffing, since there aren't any real HTTP headers. But our two computers, (and nobody else's) are sniffing and ignoring headers.

Slow pages frustrate visitors, increasing bounce rates and reducing conversions, while fast-loading sites enhance engagement, mobile experience, and revenue potential. Page load improvement involves compressing files, caching assets, and minimizing code, all contributing to performance gains that retain users and satisfy search algorithms. Beyond technical tweaks, user-centric strategies such as lazy loading and prioritizing above-the-fold content ensure visitors experience immediate value without waiting for every element to render.
