Exciting Things on the Horizon For CSS Layout
8.5.2020
Michelle Barker notes that it’s been a heck of a week for us CSS layout nerds.
Firefox has long had the best DevTools for CSS Grid, but Chrome is about to catch up and go one bit better by visualizing grid line numbers and names.
Firefox supports gap for display: flex, which is great,...
How Does Halving Work: The Code Behind The Hype
7.5.2020
Did Satoshi Nakamoto make a mistake in the Halving code?
Creating an Accessible Range Slider with CSS
7.5.2020
The accessibility trick is using <input type="range"> and wrestling it into shape with CSS rather than giving up and re-building it with divs or whatever and later forget about accessibility.
The most clever example uses an angled linear-gradient background making the input look like...
Working With MDX Custom Elements and Shortcodes
7.5.2020
MDX is a killer feature for things like blogs, slide decks and component documentation. It allows you to write Markdown without worrying about HTML elements, their formatting and placement while sprinkling in the magic of custom React components when necessary.
Let’s harness that magic and look...
Static Hoisting
6.5.2020
The other day in “Static or not?” I said:
[…] serving HTML from a CDN is some feat.
What I meant is that serving resources like images, CSS, and JavaScript from a CDN is fairly straightforward. The industry at large has been doing that for many years. An asset with a URL can...
How to Fix ESLint Errors Upon Save in VS Code
6.5.2020
Two of the most prominent utilities in web development today are ESLint and Microsoft’s Visual Studio Code. I enjoy using both, and I love the integration between both tools, but warnings from ESLint inside Visual Studio Code aren’t fulfilling — I’d rather lint errors...
`lh` and `rlh` units
5.5.2020
There’s some new units I was totally unaware of from the Level 4 spec for CSS values! The lh unit is “equal to the computed value of line-height” and rlh is the same only of the root element (probably the <html> element) rather than the current element.
Why would that...
Playing With (Fake) Container Queries With watched-box & resizeasaurus
5.5.2020
Heydon’s <watched-box> is a damn fantastic tool. It’s a custom element that essentially does container queries by way of class names that get added to the box based on size breakpoints that are calculated with ResizeObserver. It’s like a cleaner version of what Philip...
No-Comma Color Functions in CSS
4.5.2020
There have been a couple of viral tweets about this lately, one from Adam Argyle and one from Mathias Bynes. This is a nice change that makes CSS a bit more clear. Before, every single color function actually needs two functions, one for transparency and one without, this eliminates that need...
Creating a Gauge in React
3.5.2020
You should really look at everything Amelia does, but I get extra excited about her interactive blog posts. Her latest about creating a gauge with SVG in React is unreal. Just the stuff about understanding viewBox is amazing and that’s like 10% of it.
Don’t miss her earlier posts like...
Blockfolio Quietly Patches Years-Old Security Hole That Exposed Source Code
1.5.2020
The security vulnerability, which appeared in older versions of its application, could have allowed a bad actor to steal closed source code and possibly inject their own code into Blockfolio’s Github repository and, from there, into the app itself
React Integration Testing: Greater Coverage, Fewer Tests
1.5.2020
Integration tests are a natural fit for interactive websites, like ones you might build with React. They validate how a user interacts with your app without the overhead of end-to-end testing. 
This article follows an exercise that starts with a simple website, validates behavior with unit...
Some Innocent Fun With HTML Video and Progress
30.4.2020
The idea came while watching a mandatory training video on bullying in the workplace. I can just hear High School Geoff LOL-ing about a wimp like me have to watch that thing.
But here we are.
The video UI was actually lovely, but it was the progress bar that really caught my attention – or rather...
Click Once, Select All; Click Again, Select Normally
29.4.2020
A bonafide CSS trick from Will Boyd!
Force all the content of an element to be selected when clicked with user-select: all;
If you click a second time, let the user select just parts of the text as normal.
Second click? Well, it’s a trick. You’re really using a time-delayed...
How to Redirect a Search Form to a Site-Scoped Google Search
29.4.2020
This is just a tiny little trick that might be helpful on a site where you don’t have the time or desire to build out a really good on-site search solution. Google.com itself can perform searches scoped to one particular site. The trick is getting people there using that special syntax...
@property
25.4.2020
The @property is totally new to me, but I see it’s headed to Chrome, so I suppose it’s good to know about!
There is a draft spec and an “intent to ship” document. The code from that document shows:
@property --my-property {
syntax: "<color";
initial-value: green;

SVG, Favicons, and All the Fun Things We Can Do With Them
24.4.2020
Favicons are the little icons you see in your browser tab. They help you understand which site is which when you’re scanning through your browser’s bookmarks and open tabs. They’re a neat part of internet history that are capable of performing some cool tricks.
One very new trick is the ability...
Different Approaches to Responsive CSS Motion Path
24.4.2020
As a follow-up to Jhey’s recent post on responsive motion paths, Michelle Barker notes that another approach could be to just transform: scale() the whole dang element.
The trade-off there is that you’re scaling both the path and the element on the path at the same time; Jhey’s...
Some Little Improvements to My VS Code Workflow (Workspaces, Icons, Tasks)
22.4.2020
I did a little thing the other day that I didn’t know was possible until then. I had a project folder open in VS Code like I always do, and I added another different root folder to the window. I always assumed when you had a project open, it was one top level root folder and that’s...
My Visual Studio Code Setup: Extensions and Themes
22.4.2020
Matthias Ott’s posted his VS Code setup. I find lists like this (I rounded up some recent updates of my own) irresistible, probably because, like y’all, I spend an awful lot of time in VS Code and wanna make sure I’m getting the most out of it.
Things from the list that stood...
