CSS Pie Timer Re-Revisited
12.5.2021
Kitty reflected on an ancient blog post here on CSS-Tricks on how to make an animated pie timer. The old technique is still clever. The new technique is equally clever and much easier. I particularly like the steps() animation function…

Let’s Create an Image Pop-Out Effect With SVG Clip Path

Jim Nielsen:

Refreshing indeed:

Animating a CSS Gradient Border
8.2.2021
This little trick for gradient borders is super useful:
.border-gradient {
border: 5px solid;
border-image-slice: 1;
border-image-source: linear-gradient(to left, #743ad5, #d53a9d);
}
Here’s some basic demos from our article on the subject. Sephanie Eckles was sharing around the idea...
Styling Web Components

Monorepo

I’m not exactly a large-scale DevOps guy, but I can tell ya we’ve been moving back toward a monorepo at CodePen and it’s rife with advantages over a system with lots of smaller repos. For us, I mean. It’s …

How to Make an Area Chart With CSS
2.12.2020
You might know a few ways to create charts with pure CSS. Some of them are covered here on CSS-Tricks, and many others can be found on CodePen, but I haven’t seen many examples of “area charts” (imagine a line chart with the bottom area filled in), particularly any in HTML and CSS alone. In this...
Super Tiny Icons
30.11.2020
A bunch of SVG icons (of popular things) all under 1KB. SVG is awesome for golfing.
I was going to add a CodePen logo but there is already one in there at 375 Bytes. I’ve got one at 208 Bytes, based on a logo update David DeSandro did for us a couple years back.

Exploring What the Details and Summary Elements Can Do

We’ve mentioned before just how great the <details> and <summary> elements are. They’re great for quickly making accordions that are accessible to touch, mouse, and keyboard input:

Thinking Outside the Box with CSS Grid

Great tutorial from Alex Trost (based on some demos, like this one, from Andy Barefoot) showcasing how, while CSS grid has straight grid lines across and down, you can place items across grid lines creating a staggered effect that looks pretty rad. Grid-like, but it appears to align to diagonal...
CSS Background Patterns
17.11.2020
Nice little tool from Jim Raptis: CSS Background Patterns. A bunch of easy-to-customize and copy-and-paste backgrounds that use hard stop CSS gradients to make classy patterns. Not quite as flexible as SVG backgrounds, but just as lightweight.

The Cleanest Trick for Autogrowing Textareas
11.11.2020
Earlier this year I wrote a bit about autogrowing textareas and inputs. The idea was to make a <textarea> more like a <div> so it expands in height as much as it needs to in order to contain the current value. It’s almost weird there isn’t a simple native solution...
