Lazy Loaded Prefill Embeds
13.7.2020
Lemme sum this up:
CodePen has Embedded Pens. Build a Pen on CodePen, embed it on any other site.
We also offer Prefill Embeds, which remove that first step. With Prefill Embeds, the Pen doesn’t need to exist on CodePen at all. You pass in the code and settings you want to appear in...
Everything You Need to Know About FLIP Animations in React
16.6.2020
With a very recent Safari update, Web Animations API (WAAPI) is now supported without a flag in all modern browsers (except IE).  Here’s a handy Pen where you can check which features your browser supports. The WAAPI is a nice way to do animation (that needs to be done in JavaScript) because...
On fixed elements and backgrounds
3.6.2020
After just playing with apsect-ratio and being pleasantly surprised at how intuitive it is, here’s an example of CSS acting unintuitively:
If you have a fixed element on your page, which means it doesn’t move when you scroll, you might realise that it no longer acts fixed if you apply a...
A New Way to Delay Keyframes Animations
2.6.2020
If you’ve ever wanted to add a pause between each iteration of your CSS @keyframes animation, you’ve probably been frustrated to find there’s no built-in way to do it in CSS. Sure, we can delay the start of a set of @keyframes with animation-delay, but there’s no way to add time between...
Fake Code
21.4.2020
Here’s a fun little idea from Knut Synstad. You give it the URL of a GitHub Gist and it converts the Gist into grayscale rounded blobs (SVG) that sorta look like code if you squint. Maybe fun for interesting dynamic backgrounds or for whatever you might use code-looking stock art for.
It...
Can JavaScript Detect the Browser’s Zoom Level?
21.4.2020
No, not really.
My first guess was that this was intentionally not exposed in browsers because browsers intentionally don’t want us fighting it — or making well-intentioned but bad-outcome decisions based on that info. But I don’t see any evidence of that.

CSS Findings From The New Facebook Design
7.4.2020
Ahmad Shadeed digs around the new Facebook’s front-end code.
One that stood out to me:
.element {
inset: 4px 0;
/* Which is equivalent to: top: 4px, bottom: 4px, left: 0, right: 0 */
}
Whaaat? This is the first I’ve heard of the inset property. Ahmad said he saw it working...
CSS-Only Marquee Effect
5.4.2020
You make sure the text is more than twice the width of the screen, then use negative translate animations to do the marquee movement.
You’ll probably want to aria-hidden all but one of them if you need to duplicate the text. Or, you could use a very clever CSS trick...
How to use CSS Scroll Snap
27.3.2020
Nada Rifki demonstrates the scroll-snap-type and scroll-snap-alignCSS properties. I like that the demo shows that the items in the scrolling container can be different sizes. It is the edges of those children that matter, not some fixed snapping distance.
I like Max Kohler's coverage...
Shelter-in-Place for Cash? 2 Bills Submitted by US Congress Mention ‘Digital Dollars’
24.3.2020
During the last few days, members of the U.S. Congress have been trying to pen a stimulus plan to help the American economy. Since then, a few bills have been submitted by representatives and two particular proposals House democrats have tabled talk about a “digital dollar”...
A Few Background Patterns Sites
18.3.2020
If I need a quick background pattern to spruce something up, I often think of the CSS3 Patterns Gallery. Some of those are pretty intense but remember they are easily editable because they are just CSS. That means you could take these bold zags and chill them out.

Flexbox and absolute positioning
18.3.2020
Chen Hui Jing notes that when you absolutely position a flex item, it's no longer part of the flex layout. Except... it kinda is a little bit. If you make the child position: absolute; but don't apply any top/right/bottom/left properties, then flexbox alignment will still apply to it.
It's odd...
A Complete Guide to calc() in CSS
17.3.2020
CSS has a special calc() function for doing basic math. Here's an example:
.main-content {
/* Subtract 80px from 100vh */
height: calc(100vh - 80px);
}
In this guide, let's cover just about everything there is to know about this very useful function.
calc() is for values

Weaving a Line Through Text in CSS
26.2.2020
Earlier this year, I came across this demo by Florin Pop, which makes a line go either over or under the letters of a single line heading. I thought this was a cool idea, but there were a few little things about the implementation I felt I could simplify and improve at the same time.
First off,...
Get Moving (or not) with CSS Motion Path
3.2.2020
We just linked up the idea that offset-path can be cleverly used to set type on a path. Don't miss Michelle Barker's experimentation either, with drawing paths or animating text along a path.
Dan Wilson has also been following this tech for quite a while and points out why the sudden surge...
Use and Reuse Everything in SVG… Even Animations!
28.1.2020
If you are familiar with SVG and CSS animations and started to work with them often, here are some ideas you might want to keep in mind before jumping into the job. This article will be about learning how to build and optimize your code with <use> element, CSS Variables and...
The Modern Lovers
20.1.2020
I love stuff like this.
The Modern Lovers, a rock band in the 70's, play a show in Boston, probably having some poster of their own for the show.
Mike Joyce is inspired by the music and combines his love of it with the design style of Swiss Modernism to create a new poster for it.

Animate Text on Scroll
13.1.2020
We covered the idea of animating curved text not long ago when a fun New York Times article came out. All I did was peek into how they did it and extract the relevant parts to a more isolated demo.
That demo is here:

Water.css
11.1.2020
It's notable that Water.css was the #1 clicked thing from Louis Lazaris' Web Tools Weekly in 2019. It's from a 13-year old developer named Felix!
It's just a little bit of CSS you apply to class-free semantic HTML to give it nice basic responsive styles — the perfect kind of thing for a...
CSS-Only Carousel
10.1.2020
It's kind of amazing how far HTML and CSS will take you when building a carousel/slideshow.
Setting some boxes in a horizontal row with flexbox is easy.
Showing only one box at a time with overflow and making it swipable with -webkit-overflow-scrolling is easy.
You can make the "slides" line...
