A little bit ago David Darnes made a <code-pen> web component that you’d chuck HTML, CSS, and JS inside of and it would show the code and give you an “Open in CodePen” button. That’s enabled by our Prefill API. Miriam Suzanne has played with web components making an <embed-pen> that is like a replacement […]

“Regardless of where it is in the DOM.” That’s a phrase that goes through my mind in regard to a number of new CSS features and it’s so cool. I certainly spent most of my formative HTML & CSSin’ years being very careful about where things needed to go in the DOM specifically because CSS […]

Recently Heikki Lotvonen cooked up a very cool idea: what if the colorization of code output on the web could be handled by the font itself. Syntax highlighting, as it were. So rather than accomplish this with a heaping pile of <span>s with classes to colorize the text, the font file knows how to apply […]

CSS still gives me the warm fuzzies sometimes. We’ve gotten so many amazing CSS features the past few years, that each alone makes me happy. But when those features are combined, I’m often stunned and get thinking about how we’re only scratching the surface of what is to come. Take a new demo by Adam […]

We updated the Your Work section of CodePen recently. See, it used to have a dropdown menu like this that we labelled “View”: This allowed you to scope down the Pens you were looking at below (in a Grid or List view). A single <select> element like that started to feel a little awkward. Especially […]

Fine fine fine, here’s some things you could know if you were hip and into knowing things about building websites well.

CSS has a feature called Custom Properties. You know this. People also — somewhat interchangeably — refer to these as CSS variables. Somehow, that doesn’t bother me, even though I tend to be a stickler about naming things. For instance, there is no such thing as a frontend developer. There are front-end developers who focus […]

While I don’t think you should publish to Medium (at least not as the only place you publish something, you should write on your own site that you control), I get why other people do. You quickly sign up, write some words, hit publish, and the result is a pretty clean-looking presentation of your writing. […]

One of the reasons I can’t stop thinking about native Web Components is how you can use them anywhere. “Incremental adoption” is the fancy phrase, I suppose. We’ve even started using them on the new editor for CodePen we’re still hard at work on to solve some interesting issues I’m sure we’ll talk about someday. […]

Listen I ain’t trying to scare you, but this CSS stuff can get complicated. It doesn’t have to be. CSS is just selectors with key value pairs in the end. The vast majority of CSS I write is pretty darn straightforward, especially once you have a general system (what files go where? how do we […]
