At first, I thought I could just rotate the hue of HSL colors and call it a day. Since then, I've learned about perceptual color spaces, OKLCH, Bezold-Brücke effect and I still can't always get good programmatic palettes 😅 But I built Color Palette Pro to help get us halfway there: colorpalette.pro

Some days, experiments can't be clearer: ship, ship, ship. Other days, though, they don't give you a clear answer. They give you context, nuance, trade-offs. Our Experiment Decision Framework (EDF) helps cut through the noise, so you can make a more confident decision. Here's how it works 🧵

Are you teaching to the test? Breeding cobras? Letting the measure become the target? Goodhart's Law reminds us, "When a measure becomes a target, it ceases to be a good measure." This comes up all the time in A/B testing and experimentation.

I’m super excited about `text-wrap: pretty`. It does a lot more to improve typography than you might expect — at least in Safari Technology Preview 216. It improves all lines of text, not just the last 4. It enhances hyphenation & rag, not just avoiding short last lines. webkit.org/blog/16547/b...

Missing imports are always annoying. Can't my editor just fix that for me? Actually, it can and it's pretty good at it. In VS Code: "editor.codeActionsOnSave": { "source.addMissingImports": "always" } Now, missing imports are added automatically on save. Don't know why it took me so long

#tinyCSStip Create an equilateral triangle in 4 simple #CSS declarations! Such a triangle also has all vertex angles equal = (sum of angles in a triangle)/3 = 180°/3 = 60° 👉 en.wikipedia.org/wiki/Sum_of_... Knowing its edge length a, its height is a·sin(60°) Aspect ratio of the box a/(a·sin(60°))

Equilateral triangle of edge length a. All its angles are equal to 60°. A height is also drawn from the top vertex onto the horizontal base. This splits the equilateral triangle into two congruent right triangles, where this height is a cathetus opposing a 60° angle.

CSS to create a triangle with all edges equal. Set width to a custom property var(--a). Set aspect ratio to 1/sin(60deg). Give it a background just so we can see something on the screen. Set a clip-path to a polygon whose points are located in the middle of the top edge of the containing rectangular box and at the ends of the bottom edge of the same box.

Shows a CSS-created hotpink equilateral triangle on the left and the Firefox DevTools panel open on the right. The code for this triangle can be seen under the Rules tab in the Inspector. Before the `polygon()` function, there's a button toggling the CSS Shape Editor in Firefox DevTools. On clicking it, hollow circles show at the coordinates of the points listed inside the `polygon()` function. On hovering any of these coordinates inside the function, the corresponding circle fills up. This way, we can see what coordinate corresponds to what point.
