I recently saw this loader on CodePen, a pure CSS 3D rotating set of bars with a fading reflection. It's done by using an element for each bar, then duplicating each and every one of these elements to create the reflection and finally adding a gradient cover to create the fading effect. Which sounds a bit like scratching behind your right ear with the toes of your left foot! Not to mention the gradient cover method for the fading effect … Read article

I recently saw a recreation of the Twitter heart animation among the picks on CodePen. If I happen to have a bit of time, I always look through the code of demos that catch my attention to see if there's something in there that I could use or improve. In this case, I was surprised to see the demo was using an image sprite. I later learned that this is how Twitter does it. Surely it could be done … Read article

background-clip is one of those properties I've known about for years, but rarely used. Maybe just a couple of times as part of a solution to a Stack Overflow question. Until last year, when I started creating my huge collection of sliders. Some of the designs I chose to reproduce were a bit more complex and I only had one element available per slider, which happened to be an input element, meaning that I couldn't even use pseudo-elements on … Read article

It all started with this question Keith Clark recently asked on twitter.

CSS repeating-linear-gradients, do we need these? Can't the same thing be achieved with a linear-gradient and background-size?

That's a good question. … Read article

The following is a guest post by Ana Tudor. If you've seen Ana's work, perhaps you know that she uses mathematics and code together to make art. The finished pieces look like they take ages to make. But as I witness with my own eyes, Ana can think through what it takes to build something like this while doing it incredibly quickly. Here she'll explain to us the entire thought process in a step-by-step tutorial.… Read article

I have recently found myself wanting to tightly pack an SVG shape into an HTML container. By tight packing, I mean I want the outermost points of my shape to be right on the edges on the container, without anything going out of the container or getting cut off. … Read article

The following is a guest post by Ana Tudor. Ana always does a great job digging into the math behind what we can do graphically on the web. In this case, that's extra-useful as there are several ways to handle SVG transforms and they require a bit of mathematical thinking, especially converting one type to another for the best cross browser support. Here's Ana.

Just like HTML elements, SVG elements can be manipulated using transform functions. However, a lot … Read article

The following is a guest post by Ana Tudor. Perhaps you know Ana from her amazing work combining code, math, and art. Here, she shows us how we can change the normal behavior of clipping paths by applying some clever geometry, and then make it work across different technology and browsers.… Read article
