Mask Compositing: The Crash Course

At the start of 2018, as I was starting to go a bit deeper into CSS gradient masking in order to create interesting visuals one would think are impossible otherwise with just a single element and a tiny bit of CSS, I learned about a property that had previously been completely unknown to me: mask-composite.

As this is not a widely used property, I couldn't find any comprehensive resources on this topic. So, as I began to use … Read article

Simple Interactive Pie Chart with CSS Variables and Houdini Magic

I got the idea for doing something of the kind when I stumbled across this interactive SVG pie chart. While the SVG code is as compact as it gets (a single <circle></circle> element!), using strokes for creating pie chart slices is problematic as we run into rendering issues on Windows for Firefox and Edge. Plus, in 2018, we can accomplish a lot more with a lot less JavaScript!

I managed to get the following result using a single HTML … Read article

1 Element CSS Rainbow Gradient Infinity

I first got the idea to CSS something of the kind when I saw this gradient infinity logo by Infographic Paradise. The gradient doesn't look like in the original illustration, as I chose to generate the rainbow logically instead of using the Dev Tools picker or something like that, but other than that, I think I got pretty close—let's see how I did that!

The State of Changing Gradients with CSS Transitions and Animations

Back in 2012, Internet Explorer 10 came out and, among other things, it finally supported CSS gradients and, in addition to that, the ability to animate them with just CSS! No other browser supported this at the time, but I was hopeful for the future.

Sadly, six years have passed and nothing has changed in this department. Edge supports animating gradients with CSS, just like IE 10 did back then, but no other browser has added support for this. And … Read article
