General Musings with Kevin Powell

Saw this on a skateboard, had to make it in CSS.

background: repeating-linear-gradient(
  to bottom, 
  #000 0px var(--_stripe-size), 
  #fff var(--_stripe-size) var(--_stripe-gap)
);

Ended up not just being gradient text, but a repeating gradient text effect 🤓

Fun: CSS can repeat a repeating gradient

Animated gradient text is like the poster child of AI right now. Gotta have that animated gradient text sparkle button thingy to be cool.

So here! Steal the recipe.

Earlier this year, I wrote 5 CSS snippets every front-end developer should know in 2024 on web.dev. I think it holds up!

Checkout the 6 snippet 2023 edition

Today marks 28 years of CSS!

"CSS1" created in 1996.

It's cookie party day with our friends, but both kids are sick (and my spouse isn't 100% either), and we call in sick…

So, I bundled everyone on the couch, and we giggled (wrong family, too many hands, etc) our way through making cookies with AI.

A memorable video from 2019:
Video: "Why Is CSS So Weird?".

Miriam Suzanne explains how CSS is solving a weird problem, yet is guided by meaningful principles; shaping it into the powerful and complex tool it has become.

There's also a blog post.

Brad Frost shows on YouTube and a blog how LLMs (Cursor and Claude in this case) are helping him create, iterate and ideate over web design. He poses a question at the end; maybe you don't need static comps.

He asks for a funky design; it got funky.
He asks for a form; got a form.

My favorite moment was when he had Cursor rewrite the styles to use Open Props; really nice that it can unite values into tokens with reasonable logic.

Deno & Fresh have been rad.
Same goes for Deploy.

afk.

37 today. Maybe I'll upgrade this 2011 Mac Air.

This felt like a future of library customization, using @layer:

/* <tool-tip> styles */
@import "tool-tip.css" layer(components.tooltip);

/* later, in some-new-context.css */
@layer components.tooltip {
  .some-new-context tool-tip {
    --_bg: var(--surface-1);
    --_shadow-alpha: 15%;

Scope the import, then append tweaks into that scope from anywhere. Safe and sound.

TcsS - Typed Cascade Style Sheets

Why hasn't this been made yet? CSS has all the type information needed to create a comparable experience to TypeScript.

Delete your timeout functions and shake off their bugs, here's the event you really need: scrollend.

Read all about it on Chrome Developers and checkout the polyfill I wrote on NPM.

Proud to share I'll be MCing CSS Day 2023 with Michelle Barker.

Service worker update:

• Workbox added
• Offline pages (as you visit them)
• Caches images (as you download them)

Let me know if anything has broken!

2023 prediction:
libraries move to or build upon Deno instead of Node.

Art with the kids 🤘💀

Media Query Ranges

I find this so much more readable.

@media (width <= 720px) {}

Caniuse says we're waitin on Safari to bring it from TechP to Stable; aka plugin still required 😭

Thinking on ways to do UI Physics

In this GUI Challenge, I use requestAnimationFrame and custom properties to make bouncy and jelloey springy UI effects.

Things CSS Could Still Use Heading Into 2023

Just a couple of ideas!
Chris Coyier

Missing text-wrap tho!

h1, h2, h3 {
  text-wrap: balance;
}

html:has(.CertainItem:focus-visible) {
  scroll-snap-type: y mandatory;
  scroll-padding-block-start: 100px;
}

.CertainItem:focus-visible {
  scroll-snap-align: start;
}

On demand with :has(),
when a certain item is focused..

snap dat item into a nice position.

Logical Properties
Learn once, works everywhere.

Soft launch of nerdy.dev successful 🤘💀

Still more work. Expect change!

Need a dropcap?
Try the lh unit 🤓

::first-of-type::first-letter {
  line-height: 1;
  font-size: 3lh;
  float: start;
}

Bramus is blogging awesome ways to use :has() 🤓

1. CSS Islands with :has()
2. Target parents with a certain number of children

It's a good idea to follow Bramus's RSS or Twitter

In ~1 minute you can have FLIP-like animation on your page with View Transitions.

document.startViewTransition(() => {
  // modify the dom
  // - hide stuff
  // - move stuff
  // - whatever!
})

Game changer.

layouts are loops.

5 years at Google 🎉

a design tool is like a workspace with pre-squeezed paints ready. bummer is.. many artists have a preference in their paint and ink brands.

soon web browsers will offer the choice, will graphic design tools?

Grid and Subgrid layout slots
with named areas are rad 🤘💀

Placing things by name like search, tab bar, and home bar can be sweet.

Try it
(experiment in Canary, Safari Tech Preview or Firefox)

use :has() for when an element doesn't have some other element as a child, like a card without a heading 🤓

.card {
  ...
  &:not(:has(h3)) {
    /* .card's without h3's */
  }
}

Billion Laughs Attack
aka: XML bomb 💣

A type of DoS attack aimed at XML parsers that with a few liens of code, aims to consume a ton of memory.

  --ha3: var(--ha2) var(--ha2) var(--ha2);

Released roving-ux.js!

import { rovingIndex } from "roving-ux";

rovingIndex({
  element: document.querySelector("#carousel"),

User's shouldn't need to tab through each item in a list to see the next list

1. Providing keyboard list UX should be easy
2. Maintaining the last focused element should be easy
3. RTL Support

I wore this shirt from TeeJungle, it was a thing.

Released ragrid.css!

<section grid="columns" vertically-aligned="bottom">…</section>

Works like auto-layout:

1. Capable of 12-column layouts, packery, & masonry
2. Uses recognizable attributes instead of classes
3. Perfect for components
4. 528 bytes gzipped

An intrinsic first, minimal set of layout attributes.
