Animated Position of Focus Ring
27.10.2019
Maurice Mahan created FocusOverlay, a "library for creating overlays on focused elements." That description is a little confusing at you don't need a library to create focus styles. What the library actually does is animate the focus rings as focus moves from one element to another. It's based...

Why the Maximalist Narrative of Just Hodl and Wait Is Unsustainable
10.10.2019
It’s encountered all over the crypto space these days — the idea that the only correct way to “Bitcoin” is to hold and not spend, and to desperately lash out on crypto Twitter at anyone who thinks differently. But what ever happened to Satoshi’s original call for...

Link Underlines That Animate Into Block Backgrounds
23.9.2019
It's a cool little effect. The default link style has an underline (which is a good idea) and then on :hover you see the underline essentially thicken up turning into almost what it would have looked liked if you used a background-color on the link instead.
Here's an example of the effect on...
Random Notes from a JAMstack Roundtable
23.9.2019
I hosted a JAMstack roundtable discussion at Web Unleashed this past weekend. Just a few random notes from that experience.
I was surprised at first that there really is confusion that the "M" in Jamstack stands for "Markdown" (the language that compiles to HTML) rather than "Markup" (the "M"...

Initiative to Curtail Negative Interest Rates Gains Traction in Germany

Lazy load embedded YouTube videos
20.8.2019
This is a very clever idea via Arthur Corenzan. Rather than use the default YouTube embed, which adds a crapload of resources to a page whether the user plays the video or not, use the little tiny placeholder webpage that is just an image you can click that is linked to the YouTube embed.
It still...
The Differing Perspectives on CSS-in-JS
14.8.2019
Some people outright hate the idea of CSS-in-JS. Just that name is offensive. Hard no. Styling doesn't belong in CSS, it belongs in CSS, a thing that already exists and that browsers are optimized to use. Separation of concerns. Anything else is a laughable misstep, a sign of not learning from...
Using Netlify Forms and Netlify Functions to Build an Email Sign-Up Widget

26.7.2019
Have you ever had a form that needed to accept a short, arbitrary bit of text? Like a name or whatever. That's exactly what <input type="text"> is for. There are lots of different input types (and modes!), and picking the right one is a great idea.
But this little story is about something...
Zoom, CORS, and the Web
23.7.2019
It's sorta sad by funny that that big Zoom vulnerability thing was ultimately related to web technology and not really the app itself.
There is this idea of custom protocols or "URL schemes." So, like gittower:// or dropbox:// or whatever. A native app can register them, then URLs that hit them...
How I Created a Code Beautifier in Two Days
19.7.2019
I recently drew up a wireframe for a code beautifier. The next day, I decided to turn it into a real tool. The whole project took less than two days to complete.
I'd been thinking about building a new code beautifier for a while. The idea isn't unique, but every time I use someone else's tool,...
