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

CSS has a special calc() function for doing basic math. Here's an example:

/* 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.

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...

Footnote Characters
20.2.2020
They are special superset numbers that are sometimes perfect for footnotes. Here they are:
¹ ² ³ ⁴ ⁵ ⁶ ⁷ ⁸ ⁹
I generally prefer to superscript the number myself, like:
<pThis next word<sup1</suphas a footnote.</p
You'd probably add an anchor link around that as well to link to an...
Solving Sticky Hover States with @media (hover: hover)
18.2.2020
Mezo Istvan does a good job of covering the problem and a solution to it in a blog post on Medium¹.
If you tap on something that has a :hover state but you don't leave the page then, on a mobile device, there is a chance that :hover state "sticks." You'll see this with stuff like jump-links used...
Listen to your web pages
16.2.2020
A clever idea from Tom Hicks combining MutationObserver (which can "observe" changes to elements like when their attributes, text, or children change) and the Web Audio API for creating sounds. Plop this code into the console on a page where you'd like to listen to essentially any DOM change...
Toward Responsive Elements
12.2.2020
Hot news from Brian Kardell, regarding what we've been referring to as "container queries", the most hotly requested feature in CSS:
There does seem to be some general agreement on at least one part of what I am going to call instead "Responsive Design for Components" and that is that flipping...
The Hooks of React Router
12.2.2020
React Router 5 embraces the power of hooks and has introduced four different hooks to help with routing. You will find this article useful if you are looking for a quick primer on the new patterns of React Router. But before we look at hooks, we will start off with a new route rendering...
Select an Element with a Non-Empty Attribute
5.2.2020
Short answer:
[data-foo]:not([data-foo=""] {
Longer answer (same conclusion, just an explanation on why we might need this):
Say you have an element that you style with a special data-attribute:
<div data-highlight="product"</div
You want to target that element and do special things when...
Understanding Immutability in JavaScript
30.1.2020
If you haven’t worked with immutability in JavaScript before, you might find it easy to confuse it with assigning a variable to a new value, or reassignment. While it’s possible to reassign variables and values declared using let or var, you'll begin to run into issues when you try that with...
Resizing Values in Steps in CSS
30.1.2020
There actually is a steps() function in CSS, but it's only used for animation. You can't, for example, tell an element it's allowed to grow in height but only in steps of 10px. Maybe someday? I dunno. There would have to be some pretty clear use cases that something like background-repeat: space...
