Additive Animations in CSS

November 3rd, 2020

Daniel C. Wilson explains how with CSS @keyframe animations when multiple of them are applied to an element, they do both works. But if any properties are repeated, only the last one works. They override each other. I’ve seen this limitation overcome by applying keyframes to nested elements so you don’t have to do deal…

Gray Burst

November 2nd, 2020

I made this neat little gray burst thing. It’s nothing particularly special, especially compared to the amazing creativity on CodePen, but I figured I could document some of the things happening in it for learning reasons. CodePen Embed Fallback It’s SVG SVG has <line x1 y1 x2 y2>, so I figured it would be easy…

Using Your Own Design System with KendoReact Components

October 29th, 2020

Maybe you’ve already heard of (or even worked with!) KendoReact. It’s popped up in some of my day-to-day conversations, especially those about working with design systems and React. You could think of it as a component library like Bootstrap or Material Design, except the components in KendoReact are far more robust. These are interactive, state-driven…

More on content-visibility

October 28th, 2020

Back in August 2020, when the content-visiblity property in CSS trickled its way into Chrome browsers, Una Kravets and Vladimir Levin wrote about it and we covered it.

While an abundance of helpful articles may help wade through the (popular) options, they don’t magically make the decision easy. I’ve been on a quest to help make that decision easier. A colleague of mine built a static site…

October 27th, 2020

You would think that hiding content with CSS is a straightforward and solved problem, but there are multiple solutions, each one being unique. Developers most commonly use display: none to hide the content on the page. Unfortunately, this way of hiding content isn’t bulletproof because now that content is now “inaccessible” to screen readers. It’s…

Core Web Vital Tooling

October 26th, 2020

I still think the Google-devised Core Web Vitals are smart. When I first got into caring about performance, it was all: reduce requests! cache things! Make stuff smaller! And while those are all very related to web performance, they are abstractly related. Actual web performance to users are things like how long did I have…

Creating CSS Shapes with Emoji

October 23rd, 2020

CSS Shapes is a standard that lets us create geometric shapes over floated elements that cause the inline contents — usually text — around those elements to wrap along with the specified shapes. Such a shaped flow of text looks good in editorial designs or designs that work with text-heavy contents to add some visual…
