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!

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.

Spoke at Figma Config with Una!

The Future of Responsive Design

All about how the width of the viewport was never that relevant, it's more about the space a component has, the children type and count, and so much more.

What a blast, totally was with my people. I'm especially proud of a few dad jokes:

1. "Why don't you <popover> and have a <dialog> with me"
2. "It's not the PacMan rule, it's the conic gradient rule: leave room for another color stop in your chat circle."

Spoke at Smashing Conf!

Thinking on ways to do 3D SciFi Text

In this GUI Challenge, I use CSS Scroll Linked Animations to 3D tilt a few paragraphs of text, and on scroll, make them appear to vanish into the far edges of the galaxy.

Success selfie at the 🆕 Seattle office's Neon Staircase 🤘🏻💀

Multiple hard stops in a radial gradient sized as farthest-corner, this is me changing the x position first from 0 to -100, then the y in the same manor.

Viewport widths n' color gamuts;
As each widen, adapt the UI.

New post on DCC about CSS Nesting

hehe

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

but…

95% of the issues have been deps.

I have deps on NPM, deno.land, esm.sh, and unpkg… if any of these services hiccup, and I try and build; builds fail.

No single service can serve all the modules I need, and I don't need that many

💩🌈

I'm fallin behind getting my hands on some #CSS stuff!… Src of my FOMO:

• anchor() - Post by Jhey
• text-wrap: balance
• linear() - Spec by Jake
• view-transitions
• view-timeline

Hella powerful stuff there that I really don't want to let get away from me.

afk.
