@mia When people claim the web was invented to present static documents, (a giant pile of Word files), and didn’t become interactive until “web apps” were “invented”… uh. My dude. The web was interactive from day 1. Hypertext reinvented human communication. Even things like mainstream film story structure were revolutionized by the web. It was NOT “dumb” documents until 2015. The web was never supposed to be just papers. Believing so reveals ignorance to historical reality — or a corrupt agenda.

Did you see? The first beta of Safari 26.4 is out today.

What’s most exciting to you as a person making websites/apps?

I’m seeing so much about LLMs in my feed today.

Web designers and developers — how are you feeling about AI and what it means for your work?

Are you using the tools? How? What’s changing?

How do you expect AI to be used in the future for making websites & web apps?

Did you see everything in Safari Technology Preview 234?
https://webkit.org/blog/17674/release-notes-for-safari-technology-preview-234/

It’s got a lot of new features including Grid Lanes, Threaded Scroll-driven Animations, seven new Web API, and more. Plus a TON of other improvements & fixes.

Have you been wishing masonry layouts would just hurry up and arrive in CSS?? Well, happy holidays!

I’m surprised I haven’t heard more responses from web developers about the change to Safari on iOS and iPadOS regarding web apps. Now every website can be a web app (saved to the Home Screen and opened as a stand-alone app) — not just sites that have been configured a certain way by the developers.

It’s a big difference for users. Every site gets the same experience. No more mysterious sometimes-it-works-one-way, sometimes-another.

Did you know that on macOS, you can update just to Safari 26, while remaining on macOS 15 Sequoia or even macOS 14 Sonoma?

Go to  > System Settings > General > Software Update. Under “Also Available” you’ll find Safari listed. Click “Update Now”.

What do you need most from WebKit (the rendering engine for Safari that runs your HTML, CSS, JS, and more)?

If you are making websites, what could we do in WebKit to make it easier for you to create fantastic experiences for your users?

I’m especially interested in features that have shipped, but aren’t complete. What would you like to see polished or expanded?

Wow there are 22 new features in today’s Safari Technology Preview 227! Including `field-sizing`, `scrollbar-color`, `position-visibility`, more parts of Anchor Positioning, `command` and `commandfor` attributes on buttons, relative units in SVG, the `scrollend` event, Navigation API… and more: https://webkit.org/blog/17324/release-notes-for-safari-technology-preview-227/

Covid is highly contagious.

It’s airborne. Floats in the air & hangs for hours, like measles. You can show up later & get infected.

It’s incredibly damaging to the human body. Especially if you are infected over & over.

The vaccines are amazing. And yet, they do not prevent vaccinated people from being infected & contagious.

Many infectious people have no symptoms at all.

The rapid home tests have an incredibly high rate of false negatives. A negative test does NOT mean you don't have it.

Did you see? The Interop Project is now asking for proposals for what should be included in Interop 2026. Now until Sept 24th.

Yesterday’s Safari Technology Preview 225 includes auto-expanding `<details>` element and `hidden=until-found`. Plus more & more bug fixes.

Over the years, I’ve heard a lot of developers & other people wish that uBlock Origin was available for Safari. Now it is! Download for Safari 18.6 and Safari 26 beta.

Now that you’ve seen what’s coming in Safari 26… web designers & developers, what do you need most to come next? If you were setting the priorities for what happens, what would you put at the top of the list?

Did you know there’s a web browser on the Nintendo Switch 2? It’s called NetFront Browser NX and it’s built on the WebKit rendering engine. A favorite for those wanting speed, battery-life, and privacy.

Have you ever wished the browser would look at a background color and pick black or white for the text — whichever one provides more contrast? Now, the `constrast-color()` function in CSS does just that.
