Dealing with CSS performance can be quite interesting. Various factors, like what properties we use, can have detrimental effects on the usability of a page. I noticed that my site, as simple as it is, was having a bit of an issue with the fixed background that I’ve had. The scroll performance just wasn’t as smooth as I wanted it to be. I don’t remember this ever being an issue when I first built
We’re going to create a background like this in pure CSS: Of course, the simple version would be to simply create a CSS gradient (and there are tools that make creating them easy): But it just doesn’t look that great, simply because we can only create linear or radial gradients. We want more randomness, something that looks less geometric and predictable. A common method is to choose a real-life p

CSS properties are relatively crude alongside the precise control and ease of use that applications like Photoshop and InDesign offer. While developers have risen to the challenge, approaches to tooling have varied significantly. There has
Today we want to show you how the clever use of HTML, CSS sequenced animations, and SVG filters can bring to life one of the most unlikely (yet adorable) things to be seen on a web page – animals. We’ll explore two techniques for drawing the animals: one with plain HTML and CSS, and one with inline SVG background images. The animations involved are also complex, so this tutorial will focus on the
Have you wondered if you should use px, em or rem for media queries? I had the same question too, and I never figured it out, not till now. When I first created the mappy-breakpoint library, I used rem units. Then after a conversation with Sam Richard, I quickly switched to em instead because I found out there isn’t a difference between the two. In addition to em and rem, a popular unit of choice
