April 18th: Wavy Text Styles, Three.js Glass, and Pseudo 3D Weirdness

David Aerne shares an experimental HSL picker that is very satisfying to play with! Click a lightness step to set the color, which will also set the light and saturation for the whole visualization.

Chris' Corner

👋 Hey y’all! Thanks for reading. I thought it would be fun to do a little more writing in this here newsletter, so I’m going to give that a try. My goal is to make it interesting for anyone who builds websites, but with a bend toward front-end development.


I once recommended that, if you’re a front-end developer or designer that hasn’t learned much JavaScript yet, the one thing you should learn is how to toggle classes on elements. This little bit of interactivity opens a ton of possibility that is ultimately the job of us web builders. I stand by that, but I like the idea of state handling making its way to CSS as well, which is exactly what’s being explored in Miriam Suzanne’s CSS Toggles Explainer and Proposal. We’ve seen :checked used (abused?) for this a lot, I agree it’s time to see it done right.

There are many use-cases where an interaction (click/gesture) on one element toggles a ‘state’ that can be shared with other elements. This can range from toggling light/dark mode, to activating slide-in navigation, opening and closing menus, or interacting with sectioned content as tabs, accordions, or carousels.


John Boardley has been running I Love Typography for ages. I love how the site doesn’t just shine a light on the beauty of typography through writing and images alone, but the site itself is wonderfully designed, and they have started a marketplace for fonts as well. When John blogs his favorite fonts of the year, it’s always worth a read.


I love this quote that Marli Mesibov included in her recent Smashing Magazine article How To Use Storytelling In UX:

“You cannot have a page that’s too long — only one that’s too boring.”
