Set Video Playback Speed with JavaScript
2.7.2019
I love that media has moved from custom plugins (Flash…gross) to basic HTML <video> and <audio> elements. Treating these media sources as just another element allows us to use CSS filters to adjust display, for example. The less we need to do with ffmpeg or plugins, the better. I’ve been...
Fix Touch Bar Volume Buttons
30.6.2019
The touch bar on MacBooks has been a source of controversy since the beginning. Many mourned the loss of the escape key, while others refused to buy a new laptop to avoid the touch bar completely. I’ve not had many issues with the touch bar but mostly because I don’t really use it. One necessary...
How to Debug Remote Browsers
27.6.2019
It’s super frustrating when bugs pop up only in a remote browser. Something about that user, that device, or that environment is different, but I don’t know what! And of course, I can’t recreate it on my local development machine. The team at TrackJS came up with a cool way...
CSS :focus-within
25.6.2019
Using :hover to display additional information or elements is a very useful technique but a big drawback to using the hover pseudo-class is that they are usually not accessibility-friendly. Not everyone uses a mouse and some users have visual impairments, so they rely on screen readers or...
Checkout the Last Public Revision with Mercurial
19.6.2019
I’ve always preferred git over Mercurial (hg) because the feature branch workflow makes organizing code and working off of master very easy. You don’t get that with vanilla mercurial — instead, commits can just sort of apply on top of each other, without much organization....
How to Detect Text in Images
11.6.2019
Images are a great way to communicate without text but oftentimes images are used/abused to spread text within social media and advertisements. Text in images also presents an accessibility issue. The truth is that it’s important, for any number of reasons, to be able to detect text in image...

Detect if Element is a Web Component
5.6.2019
I’ve advocated for web components since before they became a spec, mostly inspired by the Dojo Toolkit’s dijit framework. Empowering first class JavaScript widgets, as opposed to a mess of DIVs and templates, always made the most sense. Now that web components exist, and awesome...
IP Geolocation API
4.6.2019
Detecting geolocation information from your user provides you a massive advantage: improved conversion, better segmenting and analytics, and providing more relevant content. There are numerous paid services which will provide geolocation info but they’re oftentimes too costly or short...
A Practical Use Case for Vue Render Functions: Building a Design System Typography Grid
30.5.2019
This post covers how I built a typography grid for a design system using Vue render functions. Here’s the demo and the code. I used render functions because they allow you to create HTML with a greater level of control than regular Vue templates, yet surprisingly I couldn’t find very much when...

Resize Observer
21.5.2019
Creating websites that are reactive and responsive used to be considered advanced but responsiveness is a necessity for successful websites and apps. We’ve added media queries, matchMedia, and a host of other APIs to help developers make responsiveness easier and now we get a new one:...
AI-Backed Image Background Removal (Sponsored)
21.5.2019
I’ve worked on dozens of eCommerce sites in my career and many of them were hamstrung by the same pain points: tax collection, payment customization, and image optimization. While tax collection and payment customization were important, image optimization was always the hardest and most...
Recursive Array.flat
17.5.2019
There was much talk about Array.prototype.flat during its early stages, starting with the name alone. Many developers preferred the name flatten but the spec differed from MooTools’ implementation. MooTools would recursively flatten an array but the new, official flat implementation was only...
Using Array reduce
14.5.2019
Every developer who specializes in any programming language will tell you there’s a powerful tool the language provides that they rarely use and wish they knew more about. For me, it’s Array.prototype.reduce. I quite enjoy the other Array methods like map, filter, and find, but reduce...

A responsive grid layout with no media queries
9.5.2019
Andy Bell made a really cool demo that shows us how to create a responsive grid layout without any media queries at all. It happens to look like this when you change the size of the browser window:
I think this is a wonderful layout technique that’s just 6 lines (!) of CSS.
.auto-grid...
Type Conversion with JavaScript Arrays
7.5.2019
JavaScript’s loose nature allows developers to employ amazing tricks to do just about anything you’d like. I’ve detailed how you can filter falsy values in arrays using a filter(Boolean) trick, but reader David Hibshman shared another trick for typecasting array values the same...
How to Patch Retry System into Super Mario ROMs
6.5.2019
I find myself watching less TV lately and much more time enjoying gamers stream on Twitch. While I too much PUBG, and enjoy watching people like Shroud and ChocoTaco hit bangers, I get more enjoyment out of Grand Poo Bear, Barbarian, and others play ultra difficult Super Mario World ROM hacks....
