9.4.2020
XRP, the cryptoasset affiliated with California-based fintech company Ripple, appears to finally be catching up after heavy selling brought it down nearly 50% during the two darkest days of March.
The rise in the price of XRP over the past 4 weeks has now brought the price almost back up to levels...
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...
Wide Gamut Color in CSS with Display-P3
31.3.2020
Here’s something I’d never heard of before: Display-P3 support in CSS Color Module Level 4 spec. This is a new color profile supported by certain displays and it introduces a much wider range of colors that we can choose from.
Right now the syntax looks something like this in CSS:

Bitcoin Mining Roundup: BTC Regains 100 Exahash, Miners Close Shop, Pre-Halving Shake-Up
30.3.2020
In 44 days, BTC miners will face the third reward halving as the block subsidy will soon shrink from 12.5 to 6.25 coins per block. Following the market carnage in mid-March, BTC’s hashrate plummeted 44% to a 2020 low of 75 exahash per second (EH/s). Since then the hashrate has climbed back...
How They Fit Together: Transform, Translate, Rotate, Scale, and Offset
30.3.2020
Firefox 72 was first out of the gate with "independent transforms." That is, instead of having to combine transforms together, like:
.el {
transform: rotate(10deg) scale(0.95) translate(10px, 10px);
}
...we can do:
.el {
rotate: 10deg;
scale: 0.95;
translate: 10px 10px;
}
That's extremely...
Did You Know the Ordered List Element Has Start and Reversed Attributes?
24.3.2020
I sure didn't! Tomek Sułkowsi shows how we can reverse the numbering of ordered lists with a simple HTML attribute:
<ol reversed<liApple</li<liBanana</li<liPear</li</ol
CodePen Embed Fallback
And the start attribute can be added to begin the list at a number other...
CSS :nth-of-class selector
23.3.2020
That's not a thing.
But it kinda is!
Bram covers how frustrating .bar:nth-child(2) is. It's not "select the second element of class .bar." It's "select the second element if it also has the class .bar." The good news? There is a real selector that does the former:
:nth-child(2 of .bar) { }

CSS2JS
20.3.2020
To add inline styles on an element in JSX, you have to do it in this object syntax, like:
<div style={{
fontSize: 16,
marginBottom: "1rem"
}}Content
</div
That might look a little weird to us folks who are so used to the CSS syntax, where it is font-size (not fontSize), margin-bottom...
What Does `playsinline` Mean in Web Video?
18.3.2020
I got myself confused about this the other day, went around searching for an answer and came up empty on finding something clear. The answer actually is quite clear and I feel a little silly for not knowing it.
With it in place, like this:
<video src="..." controls playsinline</video

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

Pre-crash Data: Number of Addresses with 1 Bitcoin Hit All-Time High
12.3.2020
The Cryptoverse had welcomed another all-time high - that of, let's call them, wholecoinddresses (addresses with at least 1 bitcoin).
The number of investors holding 1 Bitcoin (BTC) or more, known as wholecoiners, seems to be on the rise recently. Though we can't be sure how many investors...
Sass !default and themeable design systems
11.3.2020
This is a great blog post from Brad Frost where he walks us through an interesting example. Let’s say we’re making a theme and we have some Sass like this:
.c-text-input {
background-color: $form-background-color;
padding: 10px
}
If the $form-background-color variable isn’t defined then...
Block Links Are a Pain (and Maybe Just a Bad Idea)
10.3.2020
As we noted in our complete guide, you can put an <a href=""> link around whatever chunks of HTML you like. Let's call that a "block link." Like you are wanting to link up an entire "Card" of content because it makes a big clickable target.
<a href="/article/"<!-- display: block;...
Adventures in CSS Semi-Transparency Land
9.3.2020
Recently, I was asked to make some tweaks to a landing page and, among the things I found in the code, there were two semitransparent overlays — both with the same RGB values for the background-color — on top of an image. Something like this:
<img src='myImage.jpg'/>
<div...
What to Use Instead of Number Inputs
6.3.2020
You might reach for <input type="number> when you're, you know, trying to collect a number in a form. But it's got all sorts of issues. For one, sometimes what you want kinda looks like a number, but isn't one (like how a credit card number has spaces), because it's really just a string...
Currying in CSS
6.3.2020
Funny timing on this I was just looking at the website for Utopia (which is a responsive type project which I hate to admit I don't fully understand) and I came across some CSS they show off that looked like this:
:root {
--fluid-max-negative: (1 / var(--fluid-max-ratio)...
Considerations for Creating a Card Component
2.3.2020
Here's a Card component in React:
const Card = props ={
return(
<div className="card"<h2{props.title}</h2<p{props.content}</p</div)
}
It might be pretty useful! If you end up using this thing hundreds of times, now you have the ability to refactor a little bit of HTML...
Selectors Explained
2.3.2020
Have you ever found yourself either writing a CSS selector that winds up looking confusing as heck, or seen one while reading through someone's code? That happened to me the other day.
Here's what I wrote:
.site-footer__nav a:hover svg ellipse:first-child { }
At the end of it, I honestly couldn't...
