Taking something arguably boring and finding an interesting way to teach it is what I love about online education. A teammate shipped a personal project doing that and it’s 🔥 The benchmarking is one of the best features, that’s been a blocker for me testing things joachimz.me/a-more-pract...

This is clever, it stood out among Black Friday emails

Just had to add 3 environment variables to Netlify and superrrr thankful for the "import from environment variable feature" Imagine not writing a single line of code for a feature and then manually copying and pasting env variables like some kind of caveman 😜

I finally updated iOS and Mac and I kinda dig it. The actual glass styles are meh but I enjoy a lot of the UI shifts in iOS safari and in apple mail on both. Not sure I want widgets on my desktop but I see my desktop so rarely anyways

This is 🔥 codepen.io/jh3y/pen/JoG...

I really dig the UI wrapper component!

This is clever! codepen.io/cbolson/pen/...

I've looked up to Mat forever so this is a bucket list moment. He taught me JavaScript properly [checks notes] nearly a decade ago with JavaScript for Web Designers and now, my knowledge is even deeper after editing this course. It really is an evergreen resource. It's how we roll at @piccalil.li

some time back I built this little border radius visualizer to help figure out how some complex shapes might work- what's interesting (but understood) is how adjustments to specific corners of the element *seem* to affect other corners codepen.io/cobra_winfre...

We’re live!! My brand-new course, “Whimsical Animations”, is now available. 🥳🎉 whimsy.joshwcomeau.com I’m so excited to share all of my animation tools and techniques with y’all. 😄

TFW you can't find any software that will let you track map locations connected to structured data in a table in one interface so you have to vibe code it yourself. Felt, Airtable, etc. were all $100+/month for the right to do this. Lol, nope. One day of GPT-5 vibe coding and problem solved.

Can you help me out, bluesky? 🦋 When exactly did `outline` start following the `border-radius` rounding? Because in the beginning, that wasn't the case. When did that change? When did the change land in browsers? Thank you! Reposts appreciated. #CSS

Here's a #CSS study list, 100+ features to checkout from the past ~5 years. There're surprises in here for even the most knowledgeable front-end developer! nerdy.dev/cascading-se...

👋🏻❤️ I just wrapped a project with a lovely client, and I’m thinking about what’s next. So! I’ve got availability for new work starting in October 2025. Spiffed up the ol’ portfolio a bit to showcase some past projects, and to talk about the work I do: ethanmarcotte.com/work/

I have Dia invites if anyone is interested, I've been enjoying it and the UI is better than Comet IMNHO. Comet was a Windows vibe to me, but I looooove Perplexity

Had some fun playing with a CSS function for adding stylized corners to elements codepen.io/dandenney/pe... I know they won't be available for a bit, but Una's post made me nostalgic for SASS functions

🛠️ New Article: The Basics of Anchor Positioning I wrote an article covering some basics of CSS anchor positioning. Really excited to share this one! 🤩 🔗 ishadeed.com/article/anch...

My partner is in a fullstack bootcamp and I never would have imagined I'd be excitedly explaining why .map is so much better than a for loop, on the couch on Friday night. And yet, here I am

Ever cry while cutting an onion? Well, now you don’t have to! Building off of chef J. Kenji López-Alt, we found the mathematically optimal way to dice an onion. *Cutting uniform pieces has not been proven to reduce crying, but you do get bragging rights. pudding.cool/2025/08/onio...

Love this! Great share and the why and how

I’m using LLMs for a lot of coding-related things lately, but one thing it’s absolutely not ready for is installing Tailwind 4 in Astro I wonder if it’s the level of documentation? But, Astro’s implementation is 3 steps and I’ve even pointed Cursor at it

I'm hiring, again! I'm looking for a strong (senior+) design-engineer (full 50/50 split) to join our design system team. Come bring the craft back to UI design!

Here's the keycap color changer we're building in my upcoming Prismic course. I kept the animation simpler for this one, but I think it's still pretty fun to play with. Made with Three.js and @gsap-greensock.bsky.social. 3d model by the wonderful @leifs.website

Stunning product site! chroniclehq.com?utm_source=s... They really got me when I went to go scroll and my mouse changed. :chefs-kiss:
