Dealing With Stale Props and States in React’s Functional Components
12.5.2020
There’s one aspect of JavaScript that always has me pulling my hair: closures. I work with React a lot, and the overlap there is that they can sometimes be the cause of stale props and state. We’ll get into exactly what that means, but the trouble is that the data we use to build our UI can...
min(), max(), and clamp() are CSS magic!
12.5.2020
Nice video from Kevin Powell. Here are some notes, thoughts, and stuff I learned while watching it. Right when they came out, I was mostly obsessed with font-size usage, but they are just functions, so they can be used anywhere you’d use a number, like a length.
Sometimes pretty basic usage...
Turning a Fixed-Size Object into a Responsive Element
11.5.2020
I was in a situation recently where I wanted to show an iPhone on a website. I wanted users to be able to interact with an application demo on this “mock” phone, so it had to be rendered in CSS, not an image. I found a great library called marvelapp/devices.css. The library implemented the device...
Let’s Take a Deep Dive Into the CSS Contain Property
8.5.2020
Compared to the past, modern browsers have become really efficient at rendering the tangled web of HTML, CSS, and JavaScript code a typical webpage provides. It takes a mere milliseconds to render the code we give it into something people can use.
What could we, as front-end developers, do...
I’m getting back to making videos
8.5.2020
It’s probably one part coronavirus, one part new-fancy-video setup, and one part “hey this is good for CodePen too,” but I’ve been doing more videos lately. It’s nice to be back in the swing of that for a minute. There’s something fun about coming back to an...
US Central Bank Blamed for 2020 Financial Crash: ‘The Fed Is Lawless Economic Government Unto Itself’
6.5.2020
The last two months dealing with the coronavirus outbreak have been strange, to say the least, and as data rolls in more people are becoming aware that there was quite a bit of overreaction from politicians, the media, and medical professionals. A small number of people are starting to focus on...

`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...
The Anatomy of a Tablist Component in Vanilla JavaScript Versus React
5.5.2020
If you follow the undercurrent of the JavaScript community, there seems to be a divide as of late. It goes back over a decade. Really, this sort of strife has always been. Perhaps it is human nature.
Whenever a popular framework gains traction, you inevitably see people comparing it to rivals....
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...

A Book Apart Turning 10
30.4.2020
Early congratulations, A Book Apart! That’s a hell of a milestone. I’m quite sure I’ve read more A Book Apart books than any other tech book publisher.
Katel LeDu runs the ship over there, and she’s given me very special pack of discount codes that will get you my book...

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...
Using Formik to Handle Forms in React
28.4.2020
There is no doubt that web forms play an integral role in our web site or applications. By default, they provide a useful set of elements and features — from legends and fieldsets to native validation and states — but they only get us so far when we start to consider the peculiarities of using...
The Cost of Javascript Frameworks
26.4.2020
I expect this post from Tim Kadlec to be quoted in every performance conference talk for the next few years. There is a lot of data here, so please check it out for yourself, but the short story is that JavaScript-framework-powered sites are definitely heavier and more resource-intensive than...
@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;

How to Make a CSS-Only Carousel
24.4.2020
We mentioned a way to make a CSS-only carousel in a recent issue of the newsletter and I thought that a more detailed write up would be interesting and capture some of my thoughts on making one.
So, here’s what we’re making today:
There’s no JavaScript here, whatsoever! No jQuery plugins....
