Sprites on the Web β€’ Josh W. Comeau In game development, it’s common to use spritesheets for animation, but this technique isn’t as widely used on the web. Which is a shame, because we can do some pretty cool stuff with sprites! In this...

✨ I just published a new blog post about a nifty lil’ animation technique: sprites!

Sprites are used all the time in video games, but they’re less common on the web. We do have the tools to manage it in CSS, but there’s a gotcha.

In this post, I share some of the cool use cases I’ve found:

CustomStateSet - Web APIs | MDN The CustomStateSet interface of the Document Object Model stores a list of states for an autonomous custom element, and allows states to be added and removed from the set.

What is it? πŸ€”
It’s a new API that lets developers define and manage custom states on HTML elements, enabling fine-grained styling and behavior control using the :state() CSS pseudo-class.

πŸ’‘ CSS Tip!

Have you ever tried to use "auto" within clamp()? Unfortunately, it doesn't work, but it's now possible using the new calc-size()!

css-tip.com/clamp-auto/

The same applies to all the sizing values (min-content, max-content, fit-content, etc.)

Turn Websites Into Apps: How to Use Progessive Web Apps Progressive Web Apps, or PWAs, can turn app-like websites into website-like apps. Browsers are beefing up support for these useful hybrid apps, and we show you how to install and use them.

there’s never been a better time to switch to Progressive Web Apps on your phone, from Apple’s out-of-control fees, to removing public safety apps like ICEBlock, to apps accessing more of your data than you realize. odds are that β€œnative” app is just a webview anyway πŸ˜‰

Looks awesome, congrats! Can’t wait to play with it on desktop, found this small annoying bit of UX on mobile. I remember reading recently about the use of β€˜inert’ for this scenario.

Again, congrats, it’s freaking amazing!!

Window: structuredClone() method - Web APIs | MDN The structuredClone() method of the Window interface creates a deep clone of a given value using the structured clone algorithm.

Tired of hacking together deep copies with JSON.parse(JSON.stringify(...))? πŸ”

The structuredClone() method lets you safely clone complex JavaScript objects.

No data loss. No surprises. Just clean, reliable cloning.

HTML:

<!-- ❌ DON'T DO THIS 🚫 -->
<section>
  <h2>Classic</h2>
  <img src='classic-bar.png' alt=''/>
  <h2>Flavour</h2>

  <h2>
    <span>Classic</span>
    <span>Flavour</span>

```
section, h2 { display: grid }

h2 {
  grid-area: 1/ 1/ span 3;
  grid-template-rows: subgrid;

I am begging you, please don't split your heading into two separate `h2` elements with an `img` in between just to have the image in between your heading words.

This is what subgrid was made for!
