An overview of what’s new in language features, frameworks, runtimes, build tools, testing, and more.
The last part of this series is taking our site that we’ve got in GitHub and addng an Astro build process to it, then mapping a domain we own to the Netlify-hosted site.
It’s pretty straightforward to animate list items into new positions, but there is a few tricks when the specific one you’ve chosen to move needs a *different* transition.
The `satisfies` keyword allows you to assert that a certain value “satisfies” a given type, while preventing a wider type from being inferred.
You’ve got A LOT of control over the design of select menus now, and it can be done as a progressive enhancement.
A deep dive into producing an interpolated “gradient” of colors from just two provided colors.
:has() makes quantities queries both easier and more powerful. We can alter how a grid is laid out and where the children go. Or, we can just blast it into a carousel.

Dave Rupertheight: stretchnow in CSS? Works forwidthtoo.
The other day [Dave] shared a link to the new
Miriam Suzannestretchkeyword in CSS – and I saw a lot of questions about how it’s different from 100% (or 100vh when doing full-screen layouts). So I made a quick video to show how these all work!
To horizontally center an element and limit it’s width, this is easily the most common approach:
.page-wrap {
max-width: 800px;
margin: 0 auto;
}Code language: CSS (css)That could still touch the edges of a parent container though, so if need to enforce some spacing, we’d probably do that on a parent.
body {
padding: 0 1rem;
}Code language: CSS (css)There is no real problem with that, but we can smash it all into a one-liner now if you’re feeling it:
.page-wrap {
margin-inline: max(1.5rem, ((100% - 800px) / 2));
}Code language: CSS (css)The 1.5rem is the space on the outside (which could be 0), and the 500px is the max-width (or rather max-inline-size as we’re using logical properties here).
This is like one of those weirdly difficult quizzes about CSS. If you’ve got a <p> element sitting there in a totally normal basic HTML layout, then this CSS:
html {
--color: blah;
}
body {
color: blue;
}
p {
color: green;
color: var(--color);
}Code language: CSS (css)What color does the <p> render as?
It’s blue. You might think it’s green, as the value blah is an invalid color. If the CSS had…
p {
color: green;
color: blah;
}Code language: CSS (css)… then indeed it would be green. But CSS can’t know (in time) that the custom property is invalid, so it falls back to inheritance, which makes it blue from the body.
