Robert and Chris jump on to talk about our little CDN project. Maybe that’s not the right term, but we struggled with naming it. Truth be told, it’s the /public/ folder in our monorepo, where the purpose is getting files to the world wide internet at URLs that anyone can access. Our favicon is a […]

David Darnes made a <code-pen> web component, which is a basic HTML/CSS/JS panel layout that renders them into an iframe (using the very cool <syntax-highlight> web component as well). Then it ate itself when Ariel Salminen put a <code-pen> in a <code-pen>. Then the universe collapsed upon itself when Rob Rhoades made a code pen […]

Marie and Chris jump on to discuss some of the trends of what people are building on CodePen here, approximately halfway through 2025. New CSS! Hot Styles Hot Pens Time Jumps

I’m not terribly good at picking a good color palette out of thin air. My go-to is a dark look with bright colored accents, but I’m wildly envious whenever I see a beautiful website with great looking colors that are very far away from what I could pull off. Sometimes, a little inspiration can go […]

Alex & Chris get into a fairly recent technological change at CodePen where we ditched our Elasticsearch implementation for just using our own Postgres database for search. Sometimes choices like this are more about team expertise, dev environment practicalities, and complexity tradeoffs. We found this change to be much better for us, which matters! For […]

It’s one of those weeks where I just feel like posting some specimen screenshots of new-to-me typefaces that I like and have saved.

Ages ago, Firefox shipped “masonry layout” where you simply grid-template-rows: masonry; instead of defining specific rows in a grid or letting them auto-create. It wasn’t terribly powerful but it did the trick for a lot of use cases. There has been renewed interest in this the past year or so, where Google and Apple have […]

Stephen and Chris hop on to talk about how we’re saving everyone from crashed browser tabs in CodePen’s 2.0 editor. One simple: Executing JavaScript can cause a browser tab to entirely lock up, preventing you from doing anything, like potentially saving your work. It can even crash other same-domain tabs. But not on our watch! […]

Scroll-Driven Animations are a bit closer to usable now that Safari has them in Technical Preview and Firefox has them behind a flag. Chrome has released them. Saron Yitbarek has been blogging about it for Apple, and it’s nice to see. Apple hasn’t ever been super big in the “we make educational content for web […]

Chris & Rachel hop on the show to talk about the expanded privacy (access) model in the 2.0 editor (in Private Beta as we speak). Private Pens have always been a big deal, but as private as they are, if someone has the URL, they have the URL, and it doesn’t always feel very private. […]
