Since some folks asked, it’s ordinary access that’ll last like any other (you don’t need to rush to finish it by Halloween). And it goes without saying, but please be decent: it’s independently produced content for human learners 👍

Sometimes custom solutions that we build highlight deeper challenges with performance and usability, and reveal an opportunity to grow the web’s native capabilities. How doe you move from patterns that work on one website to features that are built into our browsers? @scottjehl.com at perfnow.nl

Anyone notice a recent change with @netlify.com’s costs for static builds? The hourly 11ty builds (for weather forecast data fetches) that I’d been running for months without issue on their free plan now seem like they’ll use up all the credits of even the first two paid-tier plans in under a week?

I consider myself a person who knows a lot about CSS... but @miriam.codes' knowledge eclipses mine by ~10,000%. She brings an artistry to the discipline of authoring CSS and I'm sure anyone – whether newbie or old-timer like myself – can learn a lot from her course.

I decided to opt into the Origin Trial for the newly proposed <install> element, which is currently running in Chrome and Edge browsers, on my new local surf report web app dollarslice.nyc It's there in the footer (when my feature check reveals it). Would love to see this element supported on iOS!

dollarslice.nycDaily Surf Conditions from Rockaway Beach

still pondering how to display this new element from a design perspective but for now, there's a little progressive enhancement to show the button and text, or static instructions, based on a class added via a feature test: 'HTMLInstallElement' in window.

4 June

@jensimmons.bsky.social expanding on my reply last night, it'd be great to see this in Safari as it's long been very hard to communicate how to install a PWA for iOS users, even though it's been possible (yet obscure) for years. This element makes it so simple! + @nicolesullivan.bsky.social

You can find out about how to use it and opt into the trial here developer.chrome.com/blog/install... Thanks to @patrickbrosset.com for help troubleshooting my implementation (...it turns out it won't work if you skew the button with css, which makes sense for a built in like this)

The rainy weekend here in NYC gave me some time to make something I'd been thinking about making for a while. Artwork was done in pencil, then retraced in Procreate, plus Figma for some of the vectors. 11ty build with NOAA data. Just ordered a t-shirt. Enjoy. dollarslice.nyc

If you want to learn all about web components from a human then check this out: Web Components Demystified online course is $10 this week (it'll go back to the usual $25 deal after that). It's 8 hours of video lessons, or 4 if you listen at 2x, which wouldn't offend me at all. Use the code Just10.
