GitHub Copilot Custom Skills, Agents & MCP: What Developers Need to Know

GitHub Copilot used to be easy to describe. You wrote some code, asked a question, accepted a suggestion, and kept working. That description is becoming less useful. Copilot is moving toward workflows where the model can take on a defined role, follow a reusable procedure, load project-specific knowledge, delegate work, and reach tools outside the […]

Web Privacy Guide: What Identity Resolution Means for Websites

For years, the conversation around web tracking revolved around cookies. Third-party cookies were blocked. Browsers introduced storage partitioning. Fingerprinting became a bigger privacy concern.

PHP Critical RCE Fix: What Website Owners Must Do Now

There is a question worth answering before touching a PHP server after a critical security release: Which PHP process is serving the website? Not which PHP version was installed last month. Not which version appears in a hosting dashboard. Not even necessarily the version returned by php -v. The important one is the runtime that […]

WordPress 7.1.3 Security: What Site Owners Should Check

A WordPress security update can be easy to underestimate. The dashboard shows a new version. You click Update Now. A few seconds later, the notification disappears and the site looks exactly as it did before. That is usually the goal. But WordPress 7.1.3 is not an update worth treating as routine maintenance.

CSS Typed Arithmetic: How calc() Works in Modern CSS

CSS has been getting better at doing things that once felt like they belonged in JavaScript. We already use calc() for responsive widths, spacing, positioning, and typography. But there has always been an awkward boundary around CSS math: values have types, units matter, and some calculations simply could not be expressed directly. Typed arithmetic changes […]

Accessible Web Forms: 7 Mistakes Designers Should Avoid

A form can look perfectly polished and still be difficult to use. The fields line up. The spacing feels balanced. The button has the right color. The validation animation looks great.

For years, software teams had a familiar problem: not enough developers to build everything they wanted. AI is starting to reverse that problem. Now there can be too much code.

Webflow MCP Guide: What AI Agents Can Actually Do in 2026

An AI agent that can change a Webflow page is useful. An AI agent that can look at the page, understand the system around it, change something, and then help you figure out whether that change actually worked is a different proposition. That is the direction Webflow MCP is taking. Webflow’s MCP server has been […]

JPEG XL for Web Images: Is It Finally Worth Using?

For years, JPEG XL has occupied an awkward position in web development. The format had an impressive feature set. It could compress photographs efficiently, preserve images losslessly, handle HDR and wide color, progressively decode large images, and even losslessly transcode existing JPEG files. On paper, it looked like exactly the kind of format the modern […]

Figma Specs Guide: Give AI Agents Your Design Rules

AI can look at a design and produce something that seems convincing in seconds. That is also the problem. A generated interface can have the right buttons, the right layout, and even the right brand colors while quietly breaking the rules that make a product feel consistent. Maybe the spacing is wrong. Maybe a destructive […]
