Bitcoin History Part 17: That Time Mt. Gox Destroyed 2,609 BTC
21.9.2019
Technically speaking, it’s impossible to destroy bitcoins. But it is possible to send coins to an unspendable address, rendering them redundant to all intents and purposes. In October 2011, that’s exactly what Mark Karpeles did when he consigned 2,609 BTC to eternal oblivion due to...
Table with Expando Rows
20.9.2019
"Expando Rows" is a concept where multiple related rows in a <table> are collapsed until you open them. You'd call that "progressive disclosure" in interaction design parlance.
After all these years on CSS-Tricks, I have a little better eye for what the accessibility concerns of...
Git Pathspecs and How to Use Them
19.9.2019
When I was looking through the documentation of git commands, I noticed that many of them had an option for <pathspec>. I initially thought that this was just a technical way to say “path,” and assumed that it could only accept directories and filenames. After diving into the rabbit hole...
Two Browsers Walked Into a Scrollbar
18.9.2019
Surprise: scrollbars are complicated, especially cross-browser and cross-platform.
Sometimes they take up space and sometimes they don't. Sometimes that is affected by a setting and sometimes it isn't. Sometimes you can see them and sometimes you can't unless you're actually scrolling. Styling...

While tax laws on cryptocurrency vary by jurisdiction, there are many useful tools to help you calculate crypto taxes, lower your tax liabilities, and simplify your filing — no matter where you are. Many of them work globally, supporting tax forms of multiple countries, and can import data...
A Color Picker for Product Images
17.9.2019
Sounds kind of like a hard problem doesn't it? We often don't have product shots in thousands of colors, such that we can flip out the <img src="product-red.jpg" alt="red product"> with <img src="product-blue.jpg" alt="blue product">. Nor do we typically have products in a vector...

There’s a small team of committed researchers and activists called the Ryver Bitcoin Cash group surveying Venezuelans, and giving them educational resources about the benefits of bitcoin cash. The Venezuelan country has been suffering from rapid inflation and many people distrust...
Logical Operations with CSS Variables
11.9.2019
Very often, while using switch variables (a variable that's either 0 or 1, a concept that's explained in a greater detail in in this post), I wish I could perform logical operations on them. We don't have functions like not(var(--i)) or and(var(--i), var(--k)) in CSS, but we can emulate these...
Some HTML is “Optional”
11.9.2019
There is a variety of HTML that you can just leave out of the source HTML and it's still valid markup.
Doesn't this look weird?
<p>Paragraph one.
<p>Paragraph two.
<p>Paragraph three.
It does to me, but the closing </p> tags are optional. The browser will detect...
Caniuse and MDN compatibility data collaboration
10.9.2019
Second only to "silly GIFs," I'd guess screenshots of caniuse are the most common slide graphic at web conferences. It's become the ultimate source for looking at web compatibility data in the hearts and minds of web developers.
Can I use CSS filter in Firefox? Yes. Can I use the filter() function?...
Hamburger Menu with a Side of React Hooks and Styled Components
10.9.2019
We all know what a hamburger menu is, right? When the pattern started making its way into web designs, it was both mocked and applauded for its minimalism that allows main menus to be tucked off screen, particularly on mobile where every pixel of space counts.
CSS-Tricks is all about double...
“Off The Main Thread”
10.9.2019
JavaScript is what they call "single-threaded." As Brian Barbour puts it:
This means it has one call stack and one memory heap.
We all feel a symptom of that regularly in the form of performance jank and non-interactivity on elements or entire sites. If we give JavaScript lots of jobs and it gets...
Capital Controls in Argentina Demonstrate Dangers of Government-Controlled Money
5.9.2019
The current financial system, with governments and central banks controlling the flow of money, creates impediments for people’s economic freedom. Among them is the danger that the ruling class will try to hide its mismanagement of the country’s affairs by preventing people from voting...
Working with Attributes on DOM Elements
30.8.2019
The DOM is just a little weird about some things, and the way you deal with attributes is no exception. There are a number of ways to deal with the attributes on elements. By attributes, I mean things like the id in <div id="cool"></div>. Sometimes you need to set them. Sometimes...
Crypto Lending Platforms Prepare to Assail the Banking System
30.8.2019
The battle lines have been drawn and the troops assembled. On the one side stands the combined might of the banking cartels, centuries of deeply entrenched financial infrastructure supporting them. And on the other side stands a handful of crypto companies armed with little more than a passionate...
Creating a Maintainable Icon System with Sass
28.8.2019
One of my favorite ways of adding icons to a site is by including them as data URL background images to pseudo-elements (e.g. ::after) in my CSS. This technique offers several advantages:
They don't require any additional HTTP requests other than the CSS file.
Using the background-size property...
Reverse Lookups with JavaScript
28.8.2019
I’ve always loved exploring regular expressions because they’re one of those skills that’s never taught in school — you need to pick them up on the fly, messing up and fixing them along the way. Regex’s are incredibly powerful, and one power they have are referred...
Switzerland Approves Bitcoin Banks – But With Strict Conditions Attached
27.8.2019
One of the major problems for businesses in the cryptocurrency industry is finding a bank that agrees to work with them and connect them to the traditional fiat financial system. The financial regulator in Switzerland has just made this easier by licensing two companies to serve as tailored banks...

Blocks have become an indispensable component for managing content in WordPress since the Gutenberg editor was officially released earlier this year. Not only does WordPress include some nifty blocks right out of the box, but we're starting to see plugin developers take advantage of them...
Smokescreens and Mirrors: How Does a Country Do an ICO? They Call It QE
22.8.2019
Financial regulators all around the world have been cracking down hard on ICOs for promising more than they can deliver. At the same time governments and central banks are pulling off far worse scams, such as QE, wiping out the savings of everyone that depends on them. To hide this fact they...
